This entry is trivia, which is cool and all, but not a trope. On a work, it goes on the Trivia tab.

Unintentional Period Piece

"With dated '60s references like these, we won't have much of a life in reruns!"

A work set in the present day at the time of its creation, but is so full of the culture of the time it resembles a deliberate exaggeration of the era in a work made later.

To provide a concrete example, let's say you're changing channels, and come upon an episode of Barney Miller. You see two gay men go to the police station to talk to Barney about what a recent California court decision would mean for them if they moved therenote . Even if you don't look up the decision or when the episode aired from outside sources, you can tell it places the episode at least a few years post-Stonewall (in other words, after 1969); then, they get stuck there because the station is under quarantine because a prisoner who was being held there might have had smallpox, which also places the episode quite firmly in time (the last case of smallpox was diagnosed in 1978).

Thus, even without knowing anything about the show, you can immediately say "filmed in the mid-1970s" without question. And that's an Unintentional Period Piece; by being current at the time of production, it winds up feeling like a period piece when viewed later.

Narrow Parody is a subset of this trope. Zeerust is when a work's depiction of the future becomes dated, so all works with a far-future setting belong there, not here.

While just about every work becomes somewhat of a period piece after it becomes more than a decade old due to the characters referencing old trends, wearing out of style fashions and using out of date technology, this trope only really applies to works that wear their dates so blatantly that a viewer can identify the era or even year it was made in as soon as they begin to watch it. For example, while the 1990s sitcoms Friends and Frasier show their age in many respects, they don't wear The '90s so blatantly as to have this trope apply to them.

Some jokes fall victim to this, when a history lesson is essentially required to explain the joke to folks who weren't around at the time the joke was funny. While a joke about a president who is long remembered may have many years of life, a joke about a news story that isn't well remembered 20 years later except by the people who were alive at the time or paying attention, or based on a then-popular but now long-gone ad campaign, wouldn't - inverting Don't Explain the Joke because the explanation is necessary. As years pass, the number of people who get the joke or remember the reference shrinks until the joke becomes an artifact of the generation. Historians studying an era, however, read the joke and get a good laugh out of it still and these jokes can liven up an otherwise dullish history lesson, or amuse a group of people knowledgeable of the era, or catch your grandparent off guard: "I haven't heard that joke for years!"

Subtropes include Fashion Dissonance (when this is caused by clothing and hairstyles alone) and Zeerust (when it's just the technology that's outdated). Look for examples of Technology and Society Marching On, Aluminum Christmas Trees, and scenes that would resemble Mister Sandman Sequences if they occurred in an actual period piece. Compare with Two Decades Behind, which is when something inadvertently feels like a period piece despite having been made a good time after the period it seems to be based on. Sometimes, especially when the viewer has spent too long on This Very Wiki, the very tropes in use may be recognisably of an era — such as the Nineties Anti-Hero.

Note that a work being a product of its time doesn't necessarily mean it isn't relevant or entertaining to modern audiences, even notwithstanding the kitsch or nostalgia factor (as many of the examples below will demonstrate). If the work's severe datedness also makes it inaccessible to modern audiences, then you have Values Dissonance. However, this trope can overlap with Values Dissonance if an intellectual fashion was very short-lived. When a work's popularity can be specifically dated to a certain era, that makes it Deader Than Disco. If a concept was new in its day but is now well-established and evolved beyond that, you're looking at Seinfeld Is Unfunny. Obviously films and TV shows done in black and white, or non-high definition, as well as video games, will automatically be dated for technology reasons, but if we listed them all we'd be here all day. So it would be best to judge them more by content and plot.

Important Sidenote: To avoid questionable examples, do not add a work less than 10 years old unless the situation is especially unusual. (Being completely overtaken by events by time of airing, and being called "instantly dated" by the press, have both qualified in the past.) For most works, it won't be particularly clear which ones really do bleed their production date out of every pore until roughly a decade has passed.

However - also remember that while older references zing over the heads of younger consumers - newer references zing over the heads of older consumers, too. So references from modern times can sometimes be accurate, and TV Tropes does not know time.

Examples, organized by both decade and media:

    open/close all folders 


    1920s Film 
  • Any given silent movie tends to put a pretty narrow window on things, and limitations on the medium means that anything from the dawn of cinema until "talkies" is pretty doomed to be - it has been over a century, relatively few people are even alive to genuinely relate.

    1920s Literature 


    1930s Comics 
  • The first volumes of Tintin were serialized and published weekly in the youth supplement of Belgian newspaper Le Vingtième Siècle, and included constant references to world news and celebrities of the moment (either directly or in No Celebrities Were Harmed fashion). After World War II many of these numbers were redrawn and rewritten to erase them.

    1930s Film 
  • 1934 film Smarty is a pretty amazing unintentional period piece from a couple of perspectives. First of all, it is wall-to-wall sex talk, non-stop double entendres, Joan Blondell getting a dress ripped off to expose her body in a negligee—all the Fanservice stamps this film dramatically as a memento of The Pre Code Era, the 1930-34 time frame in which for a while Hollywood got very racy indeed. But beyond that, there's the central message of the film, best encapsulated in the line of dialogue "A good sock in the eye is something every woman needs at least once in her life." The movie suggests that women need to be kept in line with the occasional punch in the face. Blondell's character Vicki quite clearly likes getting punched in the face. At the end of the film, when her formerly wishy-washy husband finally hits her like he means it, her face lights up in joy. The final scene has Vicki on the couch, looking at her husband with bedroom eyes and saying "Tony—hit me again."
  • It's technically a film from the '40s (1941), but Disney's Dumbo has a very opaque '30s reference in its very first song, "Look Out for Mr. Stork." The singers casually mention "those quintuplets," which at the time would not have been necessary to explain because it is clearly a reference to the Dionne Quintuplets, five identical French-Canadian girls who became enormous celebrities during the Depression years simply by virtue of being quintuplets (and even that is dated, as quintuplets would hardly impress anyone today because octuplets have since been born). The North American media obsessively covered the Dionne story for years (partly because it gave them an excuse to avoid any controversial economic or political topics that might have offended people in what was at the time a fairly heated social climate), with the result that the girls' entire childhood and adolescence became world news. You probably only remember the Dionne Quintuplets today if you're a Thirties buff, or a student of old newsreels, or maybe if you saw that South Park episode that subtly parodied the phenomenon with a big fuss in the town over five identical Romanian girls. Also, during the song "When I See an Elephant Fly", one of the crows makes a reference to then-President Franklin D. Roosevelt's "fireside chats".
  • The Little Rascals, which today come off as quaint stories your grandparents might tell about being children at the time. Specifically, it's about children during The Great Depression.
  • The Wizard of Oz averted this trope by cutting a musical number in which the Wicked Witch of the West sends "jitterbugs" to torment Dorothy and her friends, specifically to avoid dating the movie.
  • Gold Diggers of 1933 evokes The Great Depression in both its story and its songs. Justified in that the movie is very much about the difficulties of life in the Depression years.
  • Classic Universal horror movies like Dracula or The Wolf Man play their supernatural menaces with a straight-faced sobriety that would never have survived an audience jaded by WWII.
  • Averted/inverted in Modern Times: As the film was actually a "talkie," Charlie Chaplin wanted to thumb his nose... at the new "talkies." Even more cutting since his career (like many silent film stars) was never the same, all dialogue and sounds are somehow obscured or distorted (a hammer dropped on a concrete floor makes a muted "thud" sound, for example).
  • In A Free Soul, Ace knows a terrible secret that he's blackmailing Jan with, demanding she marry him, a secret that Dwight thinks is serious enough to kill Ace over. The secret is—that Jan and Ace had sex without benefit of marriage.
  • Gabriel Over the White House could only have been made in the brief period between the Great Depression and the rise of Nazi Germany. It depicts a President who fixes America by abolishing the Constitution, creating a private police force, ascending as an absolute dictator, and forcing other nations into submission through a superior military. And all of this is treated as a good thing. Such a President then was viewed as a willful, active leader compared to the incompetent Herbert Hoover (and even Franklin D. Roosevelt voiced his support of the film). But after seeing the damage wreaked by totalitarian dictators leading to World War II, today there's no way any such President could be shown in film again without being depicted as a tyrant.
  • The same year (1933) saw Cecil B. DeMille's This Day and Age, which depicts a group of boys taking over a small town for a day. Innocuous enough, until a gangster murders their Jewish friend. Complaining that the law won't punish the criminal, they form a mob to capture him, even torturing him over a rat pit, an action the film endorses. Then they gather around a bonfire and sing patriotic songs. Thanks to its Unfortunate Implications, movie was banned in several European countries for "strong Fascist tendencies" and has become virtually impossible to see today. Besides the movie's fascist implications, its celebration of teenaged vigilantes also became Harsher in Hindsight after the Brooke Hart incident that same year, where a lynch mob made up mostly of college students stormed a jail where two murder suspects were held and hanged them.
  • Kitty Foyle (produced in 1940, but based on a 1939 novel) is soaked in 1930s sexism, which began to look extremely dated after America entered the war following Pearl Harbor. Kitty lives in an apartment building where men aren't even allowed to visit. Her co-workers yammer on about how all they want is a man. Her handsome doctor suitor, who is meant to be the more sympathetic choice in the Love Triangle that forms the plot, plays solitaire with her on their first "date" as a test to make sure she isn't a Gold Digger. When he sees Kitty's less attractive roommates, he says "I've seen better specimens in a glass jar."

    1930s Literature 
  • Most of the works of John Steinbeck are set in this era and refer to it.

    1930s Theatre 
  • The Children's Hour takes place in the 1930s (1960s in the film) and its plot could not occur much later than that. The concept of two teachers becoming social pariahs due to allegations of being in a same-gender relationship doesn't work in modern times, where LGBT people are much more accepted.
  • The Women. The author's 1960s Setting Update of her play has been generally ignored, and revivals tend to be based on Gorgeous Period Dress.
  • A Setting Update of Of Thee I Sing reached Broadway in 1952, and flopped. Later productions have reverted to the original 1931 version, in which "the country thinks it's got depression" but it turns out that posterity (not prosperity, as President Hoover said) is just around the corner. Even educated audience members may still wonder what moratorium the chorus of reporters didn't want to know about.
  • The plot of the 1938 musical Leave It to Me! relied on the facts that relations between the US and the USSR were relatively cordial, while their relations with Nazi Germany were not, and war in Europe, though seemingly imminent, was not yet a reality. Several of these facts changed irrevocably while the musical was in its post-Broadway tour.
  • Margin for Error, written in 1939, is tied to a rather specific point in the diplomatic history of Nazi Germany. The published script specifies the setting as "prior to September, 1939," though its action would have remained mostly plausible in November, when the play opened in New York. The Communist-Nazi alliance and invasion of Poland are brought up as predicted turns of events. The movie version was made after the U.S. entered World War II, which forced the plot to be framed as a flashback.
  • Face the Music (1932) begins on the joke that The Great Depression has reduced the rich and famous to eating at the Automat, with this scene leading into a Breakaway Pop Hit that includes Herbert Hoover among its optimistic references. The second act has a drinking song in ironic salute of the not-yet-repealed Eighteenth Amendment.

    1930s Western Animation 
  • The cartoons of Max and Dave Fleischer, especially when they'd have a Musical Episode featuring Cab Calloway or Louis Armstrong. Betty Boop herself, a flapper, had already become dated by the end of the 1930s. (Twenties in this case).
  • The Porky Pig cartoon "Porky's Super Service" (released in 1937) uses this trope when it shows the (at the time ridiculous) price for gas at Porky's station. A price that, today, just about everybody would kill for (ignoring inflation). Specifically, three cents per gallon before the various taxes and fees (some of which are added for comedic effect), forty-three cents per gallon after.note 


    1940s Film 
  • In some ways, The Great Dictator is actually quite ahead of its time in its satirical depiction of World War II, since it openly mocked the Nazis when the United States was still neutral. In other ways, though, it's clearly an early-1940's film, and its depiction of Nazi Germany can seem rather jarring to modern audiences. For one thing, Charlie Chaplin hadn't known the full scale of the Holocaust at the time the film was made (years later, he said if he had known, he wouldn't have made the movie at all), so he portrays the Nazis' domestic policies as much more mild than they really were, i.e. the Nazi stand-ins are shown bullying and harassing the Jews, but nothing much worse than that. For another thing, he focuses much of the plot on the rivalry between Hitler and Mussolini (er..."Hynkel" and "Benzino") over the occupation of Austria, and portrays Mussolini as a seriously intimidating rival to Hitler; the dispute over the occupation of Austria was big news in 1940, but it's only remembered as a minor historical footnote today, and Fascist Italy is only remembered as an ineffectual ally of Nazi Germany.
  • Likewise the award-winning The Three Stooges short You Naszty Spy was based on prewar conceptions of the fascists as little more than thuggish buffoons; The Stooges (who were all Jewish) were devastated when they discovered the horrifying reality underlying all of the Nazis' pompous posturing.
  • Even that era's more serious anti-Nazi films like Fritz Lang's Man Hunt took the same line. In that film, Hitler's described as a "strutting little Caesar" whose greatest named atrocity is reintroducing the death penalty to Germany, which must have seemed underwhelming to American audiences.
  • "Confessions of a Nazi Spy," filmed in 1939 and released in 1940, portrayed a United States when it was feasible enough for German immigrants and German-Americans to have enough of a dual loyalty to the United States and Germany that they could be seduced into spying on the former for the latter. Several of the spies in the film are members of the German-American Bund, an organization that was already under Congressional investigation by 1938, and was actually outlawed by 1942, when the US was at war with Nazi Germany.
  • Gentleman's Agreement, a 1947 film about Anti-Semitism, references several 1940s politicians and scandals. At the time, its topicality made it Award Bait; today, these references would send a history professor running to The Other Wiki.
  • Mission to Moscow . The North Star and Song Of Russia are the three primary examples of American pro-Soviet films. Their blind optimism about the nobility of Josef Stalin and advocacy for the US and USSR to remain steadfast allies stands in stark contrast to nearly every American film made during the Cold War, in which the Soviet Union was at worst a tyrannical empire, or at best simply the lesser evil compared to Nazi Germany. Then there's all the millions of executions and war crimes committed by Stalin that have been uncovered over the years. Needless to say, all of the films were products of the Hollywood war effort.

    1940s Music 
  • "Route 66". The title route became a lot less relevant when freeways became the next big thing in The Fifties. U.S. Highway 66 was upgraded to freeway bypasses of many metropolitan areas, and said bypasses were later assumed into the routes of the Interstate Highway System (mostly Interstates 40, 44, and 55). The number, by then assigned to a freeway routing that had almost no connection to the original Chicago-to-California route, was finally retired in 1985. However, many portions of the old routing are still present and contain signs or monuments honoring the route's legacy (parts of it are even signed with markers reading "Historic Route 66").
  • The song "Why Don't You Do Right" refers to the year 1922 as being "twenty years ago", mathematically placing the story in the early 1940s or so. The 1961 cover by Julie London updates the year to 1941. However, the usual approach for modern performances seems to be to embrace the period and dress up the singer as a 1940s siren.

    1940s Theatre 
  • One Touch of Venus has a few throwaway lines and walk-ons that betray the fact that it was written and produced during World War II (which figures not at all into the plot).

    1940s Western Animation 


    1950s Film 
  • Hysterical Red Scare films like I Married a Communist! date to a very specific point in time.
  • Downplayed but still present with The Movie of West Side Story, which was made (very early) in The '60s but is presumably set in 1957, which is when the play debuted. Admittedly, the Jets look and talk like a product of their time, but the much grittier Sharks look like they could be from two or three decades into the future. The dialogue, however, was fairly authentic teenage slang from the '50s—which of course makes it sound incredibly dated to modern viewers.
    • Stephen Sondheim has been quoted as saying that Arthur Laurents created original slang ("Cracko, jacko!") specifically to avoid this trope. Clearly, he failed.
  • Will Success Spoil Rock Hunter? takes place in an extremely played-up version of the period in which it was made – accurately predicting how people in the future would remember the fifties.
  • Rear Window: World-traveling photographer LB Jeffries is stuck in his apartment for weeks because of a broken leg. He can't take the boredom so he looks out his window to watch his neighbors across the courtyard. If it had been at least 5 years later he would have just watched television to pass the time, but TVs weren't in every home in 1954.
  • The Seven Year Itch (1955) is a time capsule of the mid-1950s due to Values Dissonance and other reasons. For starters, the entire plot is set in motion when the wives and children of New York City leave for New England to escape the summer heat, which would not be necessary just a few years later when air-conditioning became more prevalent and reliable. The female characters, almost without exception, are seen wearing the high-waisted, long-skirted "New Look" style of dress that was already starting to pass out of fashion when this movie was made. The script is littered with subtle and not-so-subtle references to the popular culture of the time period, some of them bordering on (and in one case even crossing) the Celebrity Paradox: the characters going to a theater to see Creature from the Black Lagoon, a pretty blatant parody of From Here to Eternity, etc. Perhaps most striking, however, is the characters' discussion of the Marilyn character wearing nothing but a bikini for a U.S. Camera photo shoot: we are told that police had to show up on the beach to keep the crowd under control, and until we actually see the photo, the way the characters refer to it leads us to believe that The Girl had actually been posing nude.
  • A Face in the Crowd is set in a time when rock-and-roll and television were obviously new national crazes, and when TV programming was mostly produced in New York and was dependably wholesome. Also features numerous cameos by television celebrities of the era.
  • White Christmas is set in an America where nightclubs are places where people dress up, dance formally, and hear live entertainers perform what are today called standards. Those entertainers gain stardom by appearing on regular radio shows and starring in Broadway revues (variety shows). They travel from Florida to Vermont, and thence to New York, by train; once in New York, they appear on prime-time, live-broadcast, black & white TV, and at home the whole family gathers around to watch. And the whole plot is centered around men doing things "for an old pal from the Army" — the bond created amongst a generation by World War II.

    1950s Literature 

    1950s Live Action TV 
  • The Twilight Zone. Though most of its seasons were aired in the early '60s, it still comes off as '50s for the most part, with a lot of commentary on the Cold War and Red Scare in many episodes. There is of course still some Values Resonance to be found in some episodes though, so it varies from episode to episode.
  • Roger Ebert wrote that starting in the 1950s, television made it possible for pop-cultural fads to spread like wildfire and then burn out just as quickly as other, "cooler" fads replaced them. He could swear to this since he was an adolescent during that decade and watched quite a lot of TV, and he could date his childhood pop-culture phenomena - Davy Crockett, The Mickey Mouse Club, Zorro - not just to the mid-1950s, but to the exact year and sometimes to the exact month.

    1950s Music 
  • The original version of "Santa Baby" as sung by Eartha Kitt refers to a "[19]'54 convertible", changed in some covers to "outer space convertible." Though it can be subverted, as 1950s cars are highly sought after nowadays. Maybe if you heard this song in the 1960s or 1970s, it'd be closer to this trope.
  • Many songs by Chuck Berry are simultaneously timeless yet also time capsules of the era, especially for automobile historians (see "Maybelline", "No Money Down", "Jaguar and Thunderbird", etc.).
  • In the Clovers' 1959 song "Love Potion Number Nine" the lyrics go: "I told her that I was a flop with chicks / I've been this way since 1956". Wow, that guy's been a flop with the girls for a looooong time....
    • The year stayed at 1956 in The Searchers cover in 1965 (which is the version often heard on oldies stations). Which turns a three year dry spell into a nine year "I'd better step back and take a hard look at what's wrong with my life" serious problem. If anything, it makes even more sense that the guy is desperate enough to hunt down a gypsy for a love potion.
    • Later covers of the song avert this; you can change it to 1996 or 2006 and the song's no longer dated... for a little while.

    1950s Theatre 
  • Bells Are Ringing necessarily takes place before the rise of answering machines, which had already begun in the 1960s. It has a subplot involving fake orders placed in bulk for recordings of classical music in "all three speeds" (78 RPM died out around 1958). There's also a List Song rattling off the names of 1950s celebrities (which, like a number of similar songs from Cole Porter musicals, had a few lines revised during the original Broadway run).
  • Damn Yankees. Most obviously, the protagonist roots for and then plays for the Washington Senators, which moved in 1960 to become the Minnesota Twins.
  • Flower Drum Song lays on the 1950s slang and fashions in music and dress a bit heavily. Immigration quotas complicate the love plot, which is resolved with the help of a TV western. The lyrics to "Chop Suey" are a laundry list of people and things popular in America at the time.
  • Li'l Abner is vintage 1950s satire about atomic bomb testing and scientific optimism. The song lyrics allude to a fair number of advertising slogans of the time; "Progress Is The Root Of All Evil," whose title is a cross between an old proverb and a General Electric slogan, is about 1950s trends and failing to keep up with them.
  • The Most Happy Fella, despite being set in the 1920s, is commonly supposed to take place in the 1950s, when it was written. This is largely because the musical deliberately dropped the contemporary political topics of the 1924 play on which it was based, including all references to Prohibition.
  • John Osborne's plays Look Back in Anger and The Entertainer were cutting edge in their coarse language and format, depiction of working class Englishmen and the seedier side of British culture, ushering in the "Angry Young Man" era in British literature. They have a much more mixed reputation today, partly through Seinfeld Is Unfunny but also their dated topicality. Particularly true of The Entertainer, whose plot focuses on the long-defunct music hall tradition and myriad references to the Suez Crisis of 1956.

    1950s Western Animation 
  • 1959's Merrie Melodies cartoon "The Mouse that Jack Built" is chock-full of late 50's references, but one that would go over the head of people who don't know one World War from the othernote  is when Jack is speaking to Ed, the vault guard, who has evidently been in there a long time by the 1959 date that is assumed. Jack assumes Ed means World War II (which had been over for 14 years by this time), but then Ed drops a reference from World War I.
    Ed: Halt! Who goes there?
    Jack: It's me, Ed.
    Ed: Oh, hello, Mr. Benny. How are things on the outside? We win the war yet?
    Jack: Oh, uh... yes. Yes, we did.
    Ed: That's good. What do you think they'll do with the Kaiser?


    1960s Comics 
  • Walter Melon was written in the '60s and finished in the '90s. The comic was mainly a gag-a-day strip with a main character that had an unclear mind and encyclopedic knowledge. Pretty much 90% of the jokes in those comics would barely even work well (unless you can still laugh with jokes about people that mock old cars that have cars themselves that scream the 1960's). The dialogue is also unbelievably dated, not helped by the fact that the comic used a complex vocabulary for its time (the Spanish translator of the comic had to come up with a new joke at one point because the original joke didn't translate well into Spanish) and a lot of neologisms that don't catch on with modern viewers.

    1960s Film 
  • Love With the Proper Stranger: Quite progressive and un-dated in many ways, but clearly made before abortion was legalised in New York state in 1970.
  • Magical Mystery Tour, and not just because it starred the Beatles. Pretty much everything about it, from the bus painted in the most psychedelic colors possible to the fashions to the "experimental" (in reality incomprehensible) plot, screams 1960s.
  • Revolution (1968): This Documentary captures the feeling of the 1960s, even though the topics in them might seem old-fashioned nowadays.
  • One, Two, Three: This film literally became a period piece during shooting — when the production started, the Berlin Wall had not been erected yet, and shooting could happen at the Brandenburg Gate. However, as filming continued, and they needed to film a chase between James Cagney's character and his companions and some East German policemen that continued over the border between East and West Berlin, East Germany very unobligingly decided to put up the Wall. The film is written and performed as if still in the pre-wall period.
  • Bullitt: The police department watches in dramatic, stony silence as game-changing evidence in the case is printed by the Xerox Magnafax Telecopier, a then-revolutionary fax machine that nevertheless took minutes to send a document. You would also not find an airport even two decades later with security as lax as in the film's climax, where a character is able to carry a gun in and out of an airplane and through an airport without anyone noticing.

    1960s Literature 
  • The White Album by Joan Didion, which is an intentional reflection on the period (that goes into the early 1970s as well).
  • In the foreword to The Warriors, Sol Yurick notes that at the time the book was written, gangs had limited access to guns and cars.

    1960s Live Action TV 
  • The Brady Bunch bleeds its late 1960s/early 1970s origin, due to Fashion Dissonance and being a touch too conservative for the '70s proper. This is lampshaded in the Brady Bunch movies, where they have this attitude in the 1990s.
  • The Batman live-action series, arguably intentionally. The creators of the series deliberately went for an over-the-top "pop" palette reminiscent of 1960s artists like Andy Warhol and Roy Lichtenstein, and much of the humor derived from Batman and Robin's "old-fashioned" values becoming outdated in a more permissive era. By the time the show ended, the counterculture and hippies had started to creep in.
  • The Banana Splits, especially during the song segments. For example, in the "San Francisco" version of Wait 'Till Tomorrow, as well as the "Pop Cop" segment (which doesn't feature the Splits), you can see various, then-current styles of cars from the time.
  • Mission: Impossible clearly dates itself by a combination of two factors: on the one hand, while the conflict with the Soviet Bloc could carry the stories into the 1980s, several episodes dealing with Nazis keep it from going later into the 1970s as concerns about Nazis plotting a fourth Reich faded from popular culture. Also, many episodes mention then-extravagant amounts of money that would be considered rather paltry in the 2010s thanks to fifty years of inflation.
  • Depending on the episode, Star Trek: The Original Series has this going on alongside its Zeerust. Between the color palette, the miniskirts, the Cold War Fed/Kling politics, the civil-rights-era Aesops and Chekhov's Monkees hair, it comes across as some kind of Neo-'60s even when they aren't confronted with space hippies.
  • The Prisoner, although how unintentional it was is debatable, and the series' influence is such that it probably shaped later perception of the '60s. Nonetheless, the show criticizes Cold War power structures (with the major implication that Number Six's captors may be his own "side" and his retirement from spy service as a "matter of conscience"), and has an overall tone that can only be described as 'psychedelic', features very 1960s fashions (most notably Number Six's jacket, the multicoloured capes seen on a few characters, and the prevalence of lava lamps). The finale includes (without giving away too much) the music of The Beatles ("All You Need Is Love") and a character, thematically representing universal youth culture, calling everyone "dad" or "baby". Not all episodes are period pieces, however: one in particular, "The General", turned out to be quite prophetic with regards to the rise of digital culture and the Internet; it just does so involving a computer the size of a room that spits out printouts.

    1960s Music 
  • The Fugs: They were once the most audacious rock band out there, because they were the first to openly sing about sex, drugs and politics. As a result a lot of their material is nowadays heavily dated, because so many imitators have come in that it lost all of what made it special in the first place. And, of course, there are the many references to the Vietnam War, Kennedy, Nixon, Communism,... and so on.
  • "Happy Together" by The Turtles includes the line "If I should call you up, invest a dime..." Telephone booths often cost 50 cents nowadays, and even they are becoming obsolete as cell phones are becoming more commonplace.
  • "Mustang Sally" sung by Wilson Pickett: "I bought you a brand new Mustang, 1965..."
  • "Magic Bus" by The Who manages to still sound reasonably timeless until it betrays the fact that it was written before British currency was decimalised with "Thruppence and sixpence every day just to drive to my baby".
  • Elvis Presley song "Return to Sender" has a lyric in which the singer gets the letter returned to him stamped "no such number/no such zone". The "zone" is a reference to postal zones, a way of routing letters in large cities that was introduced in 1943 and retired in the 1960s in favor of modern-day ZIP codes.
    • If you know that ZIP actually stands/stood for "Zone Improvement Program" (which is why it's "ZIP Code," not "Zip Code"), it's still pretty clear, but most people who know that are old enough to remember zones outright.
    • "Bossa Nova Baby" has the line "Loan me a dollar and I'll buy some gas." Nowadays, $1 worth of gas might get you around the block.
  • The Beatles' "Taxman" from Revolver refers to contemporary tax rates = "One for you, nineteen for me." (a 95% supertax on earnings for British subjects in the top income bracket) and contemporary politicians - "Mr. Wilson" and "Mr. Heath" refer to Harold Wilson and Edward Heath, who were the leaders of the Labour Party and the Conservative Party, respectively.
    • "Everyone you see is full of life/It's time for tea and "Meet the Wife"." ("Meet the Wife" was a popular BBC TV sitcom of The '60s.)
    • The song "Revolution" from The White Album has the line "If you go carrying pictures of chairman Mao you ain't gonna make it with anyone anyhow". Back in the 1960s and 1970s Maoism was a bit more popular and widespread among leftist youth than it is now.
  • Many believe that Phil Ochs has largely been swept under the rug due to his habit of lifting song ideas from newspaper headlines (for a great example of this, listen to "Outside of a Small Circle of Friends"). The result is that many of his references are lost in time to all but those who were alive back then (and paying close attention to the news) and young fans who are unusually savvy in regards to the events of the time. Unfortunately, the result is that Ochs remains relatively unappreciated as one of the true pioneers and innovators of the folk/protest music movement of the sixties.
  • A lot of Frank Zappa's work are period pieces, most blatantly with We're Only in It for the Money, which satirizes the hippie movement.
  • Scott McKenzie's One-Hit Wonder "San Francisco (Be Sure to Wear Flowers in Your Hair)", dates from a very specific time, namely the spring and summer of 1967 in San Francisco, popularly known as the "Summer of Love". Similar songs like "Let's Go To San Francisco" (The Flowerpot Men), "San Franciscan Nights" (The Animals), "California Dreamin'" (The Mamas & the Papas) have dated for the same reasons.
  • The Ventures' Christmas Album has holiday standards arranged around hooks from contemporary pop hits like "I Feel Fine", "She's Not There", and "When You Walk in the Room", making it unmistakably mid-1960s.
  • Whilst the The Beatles' original Sergeant Pepper's album (1967) is viewed today as a timeless classic, the many imitators that were rushed out by other record companies to cash in on its success have dated badly. The Rolling Stones' Their Satanic Majesties Request and The Moody Blues' In Search Of The Lost Chord - both intended to cash in on the mood and themes of Sergeant Pepper - today sound like pastiches of sixties' pop music with few memorable songs. Other Pepper imitations which now sound like standard products of their own decade include The Small Faces' Ogdens' Nut Gone Flake and Pink Floyd's The Piper at the Gates of Dawn.
  • "Kay" by John Wesley Ryles, a 1968 country music song about a broken-hearted taxicab driver. Two of his customers are soldiers who tell the protagonist "how they hate that war in Vietnam". When Daryle Singletary covered the song in 2002, he changed the line to "how they won that war in Afghanistan".
  • Motown band The Marvelettes had a hit in 1962 with "Beechwood 4-5789", however telephone exchange names (like the title is) were phased out later that same decade.
  • Jidousha Sho-ka (which translate to Automobile Show Song, with the Sho-ka doubling as a Fun with Homophones, as it also means "song") is a snapshot of the car culture of 60s Japan, as it lists off a bunch of automobile brands and companies that were known among the gerneral populace back then; many of which have since been either discontinued or have faded out entirely. Examples include Packardnote , Opelnote , and Bellettnote  Particular mention goes to the prominence of American brands and the comparative lack of German brands. This song shows just how American cars dominated the import car market of Japan Had this song been made today, there would be a lot more mention of German brands such as BMW and Porsche as they've overtaken The Big Three in terms of its popularity in Japan since the 70s.

    1960s Theatre 
  • Hair focused heavily on The '60s while they were still going on, but did so intentionally.
  • The Boys in the Band is very much a look at the self-loathing, dread and neurosis in a pre-Stonewall gay culture - especially since it hit the stage in 1968, one year before the Stonewall Rebellion. In fact, when William Friedkin adapted the play for the screen in 1970, right when gay liberation and pride were on the rise, he was excoriated for putting together a "throwback" to the days of gay shame.
  • The original version of the musical How Now, Dow Jones is filled with topical and cultural references highly specific to 1967. (These were extensively revised for the show's 2009 revival.)
    • The plot is driven around a young woman who's frustrated because her fiancé won't marry her until the Dow Jones Industrial Average rises above 1,000.note 
    • Many jokes rely on the audience being familiar with Lane Bryant (a women's clothing store popular at that time) and The Graduate.
    • One scene that requires a set, costumes, and actors that aren't used anywhere else in the production is a parody of a then-current Dreyfus Fund commercial featuring a lion emerging from the subway and moving along Wall Street.

    1960s Western Animation 
  • Scooby-Doo, thanks in no small part to the bubblegum pop background music during some chase scenes (starting with the second season in 1970 — which makes this show a good candidate for the 1970s entries as well!).
  • As noted in the page quote, Rocky and Bullwinkle. Ironically, Rocky and Bullwinkle has had a much longer life in reruns — appearing in syndication through the 1960s, '70s and '80s, on Nickelodeon in the early 1990s, and occasionally elsewhere since then — than the show poking fun at it in the page quote (Tiny Toon Adventures hadn't been seen much on TV since the late 1990s until The Hub brought it back in 2013). It helps that there are over 100 episodes and the rights aren't owned by any of the big networks note  (so it's easier to negotiate syndication rights from area to area), whereas Tiny Toons has only 98 and is owned by Warner Bros., which is co-owned with the Turner networks.
  • The Flintstones and The Jetsons, despite taking place in the past and the future respectively, have enough 1960s pop culture references that they come off as "The 1960s With Cavemen" or "The 1960s With Flying Cars".
    • The 1980s Jetsons revival is a weird double example, essentially being 1980s pop culture references in a 1960s-style future.
  • Fellow animated sitcom Top Cat falls under this too, from its sixties slang, to the running gag of Top Cat constantly using Officer Dibble's now obsolete police phone.
  • The 1967 Looney Tunes short Daffy's Diner has Daffy using DDT to give the rubber mice he cooks a more authentic flavor. DDT would be banned in the early-1970's.


    2010s Anime & Manga 
  • A flashback to Takeo and Suna as elementary schoolers in My Love Story!! has them playing with a Wii, which pins the manga as being from the early-to-mid 2010s as the characters are high schoolers present-time.
  • Osomatsu-san is filled to the brink with Shout Outs to 2010-2015 anime such as Attack on Titan and Haikyuu!!. It also has a lot of focus on mid-2010s Japanese culture.
  • The English dub of Prison School contains a reference to a certain mid-2010s Internet movement towards the tail-end of its (short) relevance. Even people in the movement were quick to criticize the joke as being instantly dated.
  • A freeze-frame shot in the first episode of Papa no Iukoto o Kikinasai! shows an escalator at a monorail station that is not being used with a sign that says the escalator is turned off to conserve energy, dating the show precisely to the immediate summer after the 3.11 earthquake and nuclear disaster which resulted in an energy crisis after all nuclear power plants were shut down.

     2010s Comic Books 
  • The 2015 IDW Jem and the Holograms comics are obviously set in the early to mid 2010s. Everything from their haircuts to phones and the references they make (such as how Roxy hates social media sites like Tumblr and Twitter or how Kimber loves the Superbowl sharks) date the comic. It could be intentional as the 1980s cartoon is the embodiment of everything 80s pop and thus the reboot should be just the same.
  • The very first issue of the 2015 Archie reboot has Archie playing a Wii U, dating it to between November 2012, when the console was released, and March 2017, when the Nintendo NX was released.

    2010s Film 
  • 21 Jump Street relies on things that have changed among teenagers between the mid-2000s and early 2010s for much of its humor.
    • The film itself became somewhat dated as hipsters, the "retro style" and dubstep were seen as little more than novelties back then, but became the mainstream by the time 22 Jump came out (also being heavily featured in it). Not to mention that the "late 70s-esque" outfits that were seen as "cool" in 2011 have been overshadowed by sharper clothes.
  • The Eddie Murphy comedy film A Thousand Words was made in 2008 but released in 2012. It featured Flip Phone product placement, the novel The Shack was referred to as a hot trend, and the protagonist was a wealthy literary agent whose job would not exist in an e-book era. Many critics used the phrase "Unintentional Period Piece" in their reviews.
  • An example that falls into both the '00s and the '10s: David O. Russell's now-disowned Black Comedy Accidental Love (originally known as Nailed) ultimately became this upon its release in early 2015, after nearly seven years on the shelf due to a Troubled Production. When it began filming in 2008, the premise of a waitress with a nail lodged in her skull fighting for health insurance was timely. Now with American society marching on due to the Affordable Care Act, this premise is now considerably dated.
  • The Bling Ring. Even discounting the fact that it's Based on a True Story, the film is very much a satire of the celebrity worship and youth culture of the late '00s and early '10s, complete with a cameo by Paris Hilton As Herself.
  • The zombie flick Cockneys vs. Zombies had prominent shots of a half-constructed Shard, putting the filming squarely around late 2010 or early 2011 even though the film wasn't released until mid-2012. What makes it worse that The Shard was not vital to the plot and was simply used to highlight the Scenery Gorn. They could have omitted it or included the finished building in post-prod and averted this trope.
  • The 2011 slasher parody Detention, which is crammed with jokes about Torture Porn films, fad diets, contemporary pop and indie rock, text-speak, and the wave of '90s nostalgia that was rising at the time. The opening scene is almost as much a "Mister Sandman" Sequence for 2011 as what we see later in the film for 1992, with the line "your lack of faith in the durability of Kesha is disturbing" ringing Hilarious in Hindsight given how quickly she vanished from pop culture (or a "Funny Aneurysm" Moment, given precisely how and why she vanished). One of the film's subplots also involves a millennial teenage girl and her Generation X mother undergoing a "Freaky Friday" Flip, with the resulting generation gap being Played for Laughs; one scene has the mother (in her daughter's body) remarking about how her generation never had any great crises or struggles, to which the teenagers around her (thinking that she's still her daughter) respond by bringing up 9/11, the war in Afghanistan, Hurricane Katrina, and the death of Heath Ledger — all historic touchstones of the millennial generation.
  • God Bless America, an example of the '00s hanging over into the early '10s. Among the (literal) targets of this pop culture satire are a Pompous Political Pundit in the vein of Bill O'Reilly, a Spoiled Brat featured on a My Super Sweet Sixteen-type show, a militant fundamentalist church in the vein of the Westboro Baptists, and everybody on the set of a reality singing competition based on American Idol.
  • One of io9's chief criticisms of the 2010 movie adaptation of Gulliver's Travels was that it was "immediately dated" to 2010. The review called it "a ferociously shameless time capsule of 2010 pop culture."
  • The New Zealand-made film The Holy Roller has sadly become this, thanks to the Canterbury earthquakes of 2010 and 2011.
  • 2011's Horrible Bosses was very much a product of its Great Recession-era time. One of the main reasons why the main characters can't quit their jobs (besides blackmail by their respective bosses) is because, in the current economy, they likely won't be able to find jobs as stable as what they have. To drive this point home, they run into a former friend of theirs who worked at Lehman Brothers and lost everything after that company collapsed (the incident that set off the economic crisis), and now works as a male prostitute.
  • One of the main characters in Iron Sky is a US President based on Sarah Palin, which manages to date it to the brief moment in the late '00s and early '10s when Palin was a major political figure. By the time the film was released in 2012, she was already at the tail end of her fame and was only taken seriously by her supporters; the entire joke was about how ridiculous the idea of Palin becoming President would be. Nowadays, she's barely a blip on the cultural and political radar, rendering the joke quite dated.
  • The 2015 Live-Action Adaptation of Jem and the Holograms, which updates the story to depict the protagonists' rise to fame as occurring chiefly through social media and YouTube. A common theme in many reviews was how "of the moment" the subject matter was in how it built itself entirely around its portrayal of New Media.
  • L.A. Slasher is a horror-comedy parodying the celebrity culture of the late '00s and early '10s, particularly Reality TV stars that the titular slasher killer views as having no talent or worth to society. What makes it particularly notable is the fact that, while it was shot in 2012, it was only released in 2015, by which time most of the targets of its satire (such as Teen Mom, Paris Hilton, and a young Justin Bieber) had long since ceased to be relevant.
  • The Nut Job also dated itself right out of the gate by using "Gangnam Style" (complete with an animated Psy in the credits!) nearly two years after the song's heyday (the movie came out in January 2014).
  • The 2015 remake of Poltergeist was immediately noted by many critics (such as Angry Joe) for its attempts to update the story of the original film to incorporate smartphones, computers, RC camera drones, ghost-hunting reality shows, and other elements of contemporary life and pop culture, many of which they felt would make it painfully stand out as a product of its time ten years down the road.
  • Scream 4. Just as the original films were a reaction to the slasher movies of the prior decade (see 1990s Film), so was this one a reaction to the remake and Torture Porn trends of the 2000s, with an appropriately updated set of "rules" for modern horror movies. And in keeping with the series' Post Modernism, it also happens In-Universe, with the Film Within a Film Stab 6 featuring Ghostface taunting two victims through Facebook; one of the people watching it remarks that it sounds like a stupid attempt by some hack writer to keep the series "hip", causing the other to reply "I guess now it would be Twitter."
  • As mentioned in 2000s Film, the Seltzer and Friedberg films Vampires Suck and The Starving Games (the latter's "Gangnam Style" "joke" alone arguably throws it into this category).
  • Spring Breakers, much like the aforementioned The Bling Ring, is a satirical take on the party-hard pop culture of the early '10s. James Franco's character in particular, a Pretty Fly for a White Guy rapper/drug dealer, is a distillation of every Glam Rap stereotype of the era.
  • The 2012 film version of The Three Stooges attempts to be an updating of the famous comedy team, yet also dates itself severely by including the cast of Jersey Shore as themselves for much of the film. Jersey Shore would be cancelled later that year.
  • Deadpool has a couple references to Twitter and Instagram, as well as memetic stuff like unicorns. However, most of the quotes and references made by Deadpool himself are about things dated to The '80s (Weird Science, RoboCop (1987), Say Anything......) and, in a couple cases, to The '90s (he mentions Limp Bizkit and compares Negasonic Teenage Warhead to "Ripley from Alien³").

    2010s Literature 
  • The book Alice in tumblr-Land, a modern retelling of fairy tales, which relies on the existence of Tumblr, OKCupid, Facebook, Instagram, Youtube, etc. for most of its humour. It's painfully dated to the mid-2010s and as such will fail to be relevant within a couple of years.
  • OMG Shakespeare! is a series of books that attempts to modernize the works of William Shakespeare by making everything into text. The constant use of slang and emoji will likely quickly date them to being released circa 2015.
  • The Origami Yoda series is full of early-mid 2010s pop-culture references and views. Examples include Ambiguously Gay Murky receiving homophobic bullying, the much-disliked FunTime program showing an educational parody of Gangnam Style (though to the book's credit, the characters do mention that the song came "a few years back"), and Professor FunTime's actor receiving a role in "the upcoming Star Wars movie" (meaning that the events in the book took place sometime before December 2015, when The Force Awakens came out).
  • Ben Aaronovitch has lamented that the London Metropolitan Police reinvents itself so often that the meticulously researched Rivers of London books can usually be dated precisely to the year before they were published.

    2010s Live Action TV 
  • A funny one occurred on NCIS: Los Angeles when the subject of one episode was Libyan government agents sent by Muammar Gaddafi killing a rebel propagandist and trying to use his identity to get the rebel leadership into an ambush. Obviously written and filmed when the Libyan Civil War seemed (from the outside) to be deadlocked, by the time the episode aired (October 11, 2011) the rebels would be more properly called "the Libyan government", having been recognized as such internationally in September 2011 with Gaddafi the one on the run who should be wary of ambushes. (Gaddafi would be captured and killed on October 20, just nine days after the episode aired.) The references to The Arab Spring also clearly date the episode.
  • Breaking Bad is a curious example, considering the first season aired in 2008. However, considering the timeline of the series only takes place over the course of a year, and in the final season a character makes a reference to "whacking Bin Laden", means the series takes place no earlier than mid 2011. The use of flip-phones by every character rather than smartphones baffles some viewers, but this is a case of Shown Their Work for the main characters, as Burner Phones are very commonly used by drug dealers and other criminals because their low cost and lack of binding contracts makes them easy to dispose of and quickly replace as needed. On the other hand, smartphones do start to proliferate toward the end of the series.
  • In The Fosters' fifth episode, the morning-after pill is kept behind the counter, available to over-16s only, while the tenth episode features a fully legally sanctioned California same-sex wedding. This places each episode before and after the 2012-13 Supreme Court session, respectively.
  • Turn on almost any given episode of Glee from the second season on, and you're likely to hear at least one song that was popular at the exact time the episode was made, not to mention the frequent references to current fads.
    • This tends to be true of any "let's-put-on-a-show" fictional musical series (another example being Disney's Kids Incorporated in the 1980s and early '90s). Since the musical is essentially an old-fashioned genre, these shows often try to come across as current as possible. You might remember that the major controversy on the very first episode of Glee was the club's decision to incorporate post-1960s rock and pop music (some of it very current) into their repertoire of old show tunes.
    • Not to mention the show's tendency to embrace the cultural norms of young people during a period of rapid social change. Even though the show is not that old, it is hard to not see its wide-eyed Progressivism as a bit quaint in the face of major Conservative backlash and a Trump candidacy.
  • Despite the series starting in 2013, House of Cards (US) politically sets itself in a pre-2010 mindset by having Francis Underwood be a "Blue Dog" Democratnote  from Georgia, and having his party initially require him to be whip for their majority status in the House of Representatives. The "wave" elections of 2010 and 2014 saw virtually all the Blue Dog Democrats swept from both chambers of Congress and replaced with Tea Party Republicans, and gerrymandering drawn up by Republicans has made the House virtually unobtainable for Democrats in the 2010s.
  • How I Met Your Mother, with its frequent pop culture references to things like Inception, memes, and Fifty Shades of Grey. Possibly justified, as the Framing Device dates the show by the month/year. The references would be hip at the time of the episode.
    • Aside from pop culture references, one plot point during the first season had Ted going to a dating agency, the kind that would get killed off by online dating websites and free dating/hook-up apps.
    • Also done in universe: after Lily and Marshall have an argument, he imagines what Lily from 2006 might say, leading to 2006 Lily quoting Borat and wondering how many MySpace friends she has by 2013.
  • In season 2 of The Middle, Frankie obsesses over the "Royal Wedding" of William and Kate, firmly fixing the episode in 2011.

    2010s Music 
  • The Rise Against song "Make It Stop (September's Children)", which is about homophobic bullying and makes reference to a number of high-profile gay teen suicides.
  • "#SELFIE" by The Chainsmokers is ingrained with early-mid 2010s culture, with lyrics about taking selfies with Instagram, "Summertime Sadness", and referring to another girl as "ratchet". Todd in the Shadows, when placing the song on his list of the worst songs of 2014, used this as his justification, saying that "there was nothing else as painfully 2014 in 2014".
  • "Wiggle" by Jason Derulo is another song which refers to Instagram in its lyrics.
  • Instagram is also mentioned in Rascal Flatts' "Payback". The original line was "Get some pictures on the Internet", but it was likely specified to avoid Unfortunate Implications.
  • Ronnie Dunn, formerly one-half of Brooks & Dunn, got hit with this on his 2011 single "Cost of Livin'". The song, about a hard-working man struggling to find a new job in a tough economic climate, already dates it to the fallout of the 2007-09 Recession. But it also has the line "Three dollars and change at the pump" (including a rarely-heard edit to "four dollars and change"), which has become dated with gas prices falling into the $2 range in much of the country as of late 2014-early 2015.
  • The Thousand Foot Krutch song "I Get Wicked" contains a line that will age it quickly.
    P.S: Don't play me like a 3DS.
  • "Gun Fight" by Sick Puppies references the American presidents President Bush and President Obama, which pins the song firmly from the late 2000s to late 2010s.
  • Maddie & Tae's 2014 debut single "Girl in a Country Song" lampoons the contemporary "bro-country" trend at the time (i.e., a glut of young male country artists singing songs about partying, drinking, and hot girls). The song was one of the biggest factors in "bro-country"'s subsequent decline, and its blatant references to contemporary songs (many hit songs from the past two years are name-dropped in the lyrics) and trends put the song squarely in 2014.

    2010s Video Games 
  • Forza Horizon, released in 2012, has a rather tragic example of this that happened right from the get-go. The soundtrack features two songs from Lostprophets, something that would be unthinkable just a few months later, where frontman Ian Watkins was arrested, charged and later sentenced to 35 years in prison for committing child molestation.
  • Kantai Collection has a few lines uttered by ship girls that make references to Japanese pop-culture of when it first came out (2013), instantly dating itself to the very year.
    • One of the character makes a vague reference of Waratte Iitomo, a popular TV show that aired at noon. Said show ended a year after the game was released. Oops.
    • This also counts as an Early Installment Weirdness, however, as subsequently added characters and additional lines to existing ones make little to no pop-culture references.
  • Downplayed with The Binding of Isaac. It was first released in 2011 and contains several examples of Rage Comics faces (which were at peak popularity around 2010 or so), such as the bombs with a Trollface on them, and a few other memes such as "Shoop Da Whoop". However, when their nature will eventually be forgotten, their bizarre appearances wouldn't look too out of place among the other grotesque and unsettling character designs.

    2010s Web Original 
  • This trope is lampshaded by Matt and Pat of Two Best Friends Play during their playthrough of Resident Evil 4. Early on Matt talks about how early previews of The Evil Within have been rather mixed during the PAX video game convention in spring 2014, and then says afterward "oh wow this is going to be weird to watch in a few years." Later when Matt brings up a then-current event of Vince McMahon having lost millions of dollars, Pat comments "wow you're really dating this video now." They even eventually make a comment on how the game manages to date itself with a line about how the word "terrorism" is "such a popular word these days" (Resident Evil 4 came out in 2005, when the War on Terror was still pretty relevant).
  • Kickassia features The Nostalgia Chick impersonating Sarah Palin in her role as Vice President of the titular microstate - which some critics derided as dated even when it was first released (in mid-2010).
  • Some Jerk with a Camera's "Sabrina Goes To Disney World" episode references specific ads that were commonly played during Fall 2013 to January 2014, such as "Towin' in a Winter Wonderland" and "Blue Shield Floating Latina Mom Head". Quite unfortunately for him, these ads were switched for new ones the same day that the episode was put up, dating it from the very start.
    • Many other of his episodes parody common aspects of the video hosting site Blip, such as the loading screen, its frequent Disneyland ads, etc, all of which are since defunct now that Blip has shut down.

     2010s Western Animation 
  • A few episodes of the Un-Cancelled Futurama falls into this:
    • "The Duh-Vinci Code" makes a crack at Leonardo being unable to determine the mass of the Higgs Boson. At the time of its production (July 2010), researchers at the Large Hadron Collider famously furiously attempted to discover it. It has since been discovered and documented in March 2013.
    • "That Darn Katz!" is made up largely of lolcat jokes at their peak of popularity. They are still reasonably popular now but have been slipping out of mainstream.
    • "Decision 3012" falls into this since it's a satire on all the Barack Obama conspiracies.
    • "A Farewell to Arms" can be seen as this since the plot is a parody of the supposed end of the world in 2012.
    • A precancellation episode "I Dated A Robot" involves celebrities' personalities being downloaded onto blank robots through a company called (Kid)Nappster. This is dated to the early 2000s when Napster was popular, and has since been shutdown. The writers acknowledge this on the DVD Commentary.
  • The South Park episode "A Scauze for Applause" ends with Jesus leading the townspeople in a "Free Pussy Riot" rally, which becomes this after the members of Pussy Riot were freed in 2013.
    • However, though South Park was certainly an Unintentional Period Piece of the 2000's, it's more than likely that these recent seasons have been intentionally dating themselves to the mid 2010's considering the direct and scathing satire directed at all of the current popular trends. In particular, plot elements have been literally coming straight from things that happen in the same week since 2011 or so.
  • The Gravity Falls episode "The Stanchurian Candidate" became an accidental victim of this. The plot about Grunkle Stan's mayoral campaign becoming unpopular with the public due to his "speeches" just being whatever insane rhetoric pops into his mind, came out around the time 2016 Presidential nominee Donald Trump was gaining infamy for doing just that. The A.V. Club took notice, saying that the satire would have been more relevant if Stan's campaign actually succeeded.
  • It's likely that We Bare Bears may suffer a great deal of this in about a decade's time, with its constant references to hipster culture, smartphones, and social media in general.
  • Mostly averted in My Little Pony: Friendship Is Magic with a few exceptions.
    • The Season 1 episode "Call of the Cutie" has Ponyville's teacher Cheerilee showing a picture of herself dressed in 1980s garb. This dates the episode to the period where the episode aired (early 2010s) since it reveals herself as middle-aged.
    • Season 5's "Crusaders of the Lost Mark" had an election theme and aired around the time Donald Trump was making his bid for the U.S. Presidency's Republican nomination.
    • The My Little Pony: Equestria Girls series is very likely to become dated faster than the show. Camera phones? Check. High School Musical-esque songs? Check. Social media? Check. Email? check.
  • The original The Powerpuff Girls had its period piece elements but they were more downplayed. The Powerpuff Girls (2016) is heavy on 2010s culture, similar to We Bare Bears, and it's likely the technology (such as the smartphones) will become dated a few years down the line. The "Painbow" episode alone features both twerking and mid-2010s internet slang, and another episode shows that Bubbles makes internet memes.

Special Cases (either works which span multiple decades, or are Older Than Radio)

  • Advertising in general has a tendency to be dated to whatever time period it came out, due to its constant attempt to capture the zeitgeist of whatever era it appeared in in order to better market products. As Charlie Brooker explains:
    "Old adverts are like little nostalgia bombs, really. Each one sums up the year in which it appeared in an instant. '60s ads are cool and swinging, the '70s ads are sort of brown and grotty, whereas the '80s were characterized by power ballads and absolute swaggering fuckery like this." ... "'90s ads were all huggy-wuggy and sophisticated, whereas the noughties can't decide if they're all troubled and weird, or inspirational like this bloke whose cycling glory has prompted an identity crisis."
  • Any ad that features a photorealistic drawing rather than an actual color photograph can't be any later than the 1960s (unless, of course, the advertiser is going for a Retraux effect).
  • Honda's "One More Thing To Love About Today" ad puts its subject in the inspo board for a mid-2010s "Mister Sandman" Sequence complete with Finn and Jake and pictures of animals from memes.
  • Watching an old videotape or a DVD becomes this when the Coming Attractions are showing trailers of films that have long since been out or even already forgotten, but are preceded by "now available on video" or "now in theaters".

    Comic Books 
  • Look at any issue of Archie Comics. Even back in the early '90s, they acknowledged this with their Americana Collections, showcasing the iconic strips of each individual decade. Usually they will feature one "Love Triangle"-themed story, then dozens of others about then-current fads, or parodies of then-popular movies. The fashions of most strips shown in the Digest format issues years later also date certain stories greatly.
  • 2000 AD has an interesting relationship with this trope, being something of a Long Runner:
    • Early Judge Dredd stories were often steeped in the Cold War, with the Soviet Union surviving into the 22nd century and being the main antagonists in quite a few stories, at least until East-Meg One got nuked to oblivion. The Volgan Empire in Invasion! and especially ABC Warriors was an incredibly obvious Soviet stand-in, at least until they were retconned.
    • During The '80s, nearly every strip made some reference to Margaret Thatcher or Ronald Reagan.
    • The '90s featured strips such as the ''Space Girls'' and ''BLAIR 1'' (a parody of MACH 1, an early strip from 1977) in order to stay relevant. These were not well-recieved.
    • And, of course, there's the title itself, which did a much better job of projecting a futuristic image when the 2000 AD was actually decades in the future.
  • Many superheroes have dated origins, according to either comics canon or tradition. Bruce Wayne became Batman after seeing his parents get shot outside a movie theater showing The Mark of Zorro (1940), while Bruce Banner became The Incredible Hulk in the early 1960s while trying to stop a beatnik-like teenager from wandering onto a nuclear testing site. Understandably, many of these details have been altered by later stories.
  • Many of the early The Avengers comics ended up becoming incredibly dated, not just due to the Dirty Communist type villains common in that era, but also because of many pop culture references included in the stories.

  • In general, a film shows its age if the credits are in the beginning. Most films nowadays put the credits after the movie nowadays, in two sets, a Creative Closing Credits followed by a much longer list. But in pre-80s films, the shorter credits list would be in the front of the film, or sometimes even the entire list. This is due to old Director's Guild guidelines, since the opening credits were viewed as important for displaying the big stars and crew members. In the case of George Lucas, he was kicked out of the Director's Guild after he insisted on starting The Empire Strikes Back without the opening credits (he got a pass for A New Hope because none of them thought it would succeed). After Lucas proceeded to become a powerful filmmakers without the aid of the Guild, the rules were softened to say the "big credits" could be put in the back instead before the main list of credits.
  • The Three Stooges shorts, made from the 1930s through the 1950s, were always a product of their time.
  • James Bond:
    • Most of the Bond films, with each version of Bond being this to (roughly) one particular decade. The Sean Connery films have their feet planted in The '60s, Roger Moore's Bond is a product of The '70s, the Timothy Dalton films are products of The '80s, the Pierce Brosnan films are filled with the post-Cold War vibe of The '90s, and Daniel Craig's Darker and Edgier Bond is a man of the Turn of the Millennium and The War on Terror. Sometimes the Bond Girls' fashion choices also make the films' decades clear as day.
    • An interesting case is the aborted 1991 film The Property Of A Lady. It would have revolved around the UK's relationship with China and the disputed sovereignty of Hong Kong. However, a legal battle with former producer Albert Broccoli left the film in Development Hell for a few years. By the time all that was cleared up, the two countries were in talks of returning Hong Kong to China, which would have made the plot outdated, necessitating several rewrites. These rewrites turned the movie into GoldenEye, which dealt with the fall-out of The Great Politics Mess-Up instead.
  • West Side Story is sort of an evolutionary missing link between the more violent films of the 1970's and the whimsy of musicals of the 60's—it's likely that only in that exact timespace could that movie have been made.

  • This joke is funny, but the boy in the joke has to be from the 1970's-1990's to have a grandfather who served in World War II, making it dated, sadly. Giving this background kills the surprise.
    A boy was upstairs playing on his computer when his grandad came in the room and sat down on the bed.
    "What are you doing?" asked the grandad. "You're 18 years old and wasting your life! When I was 18 I went to Paris, I went to the Moulin Rouge, drank all night, had my way with the dancers, pissed on the barman and left without paying! Now that is how to have a good time!"
    A week later, the grandfather comes to visit again. He finds the boy still in his room, but with a broken arm in plaster, 2 black eyes and missing all his front teeth.
    "What happened?" he asked.
    "Oh Grandfather!" replied the boy. "I did what you did! I went to Paris, went to the Moulin Rouge, drank all night, had my way with the dancers, pissed all over the barman, and he beat the crap out of me!"
    "Oh dear!" replied the grandad. "Who did you go with?"
    "Just some friends, why? Who did you go with?"
    "Oh!" replied the grandad. "The Third Panzer Division."
  • The schoolchild in the Soviet joke about a show-and-tell class might be even older: "I didn't know Grandpa had been a military electrician in the war until I found this helmet with two lightning bolts in the closet."
  • Q:How do we know Adam and Eve were computer nerds?
    A:God gave Eve an Apple and Adam a Wang
  • A joke that relies on a now over-100-year-old advertising slogan:
    A man went on a sea trip with his wife, but his wife died on the trip. The captain said they did not have the facitities on board to store a body for burial on shore, they would have to do a Burial at Sea. The husband knew his wife would never stand for it, but understood and allowed it anyway. That night, sleeping in his cabin, the man kept hearing a voice softly repeating "It floats... it floats... it floats". The next night he heard it again, and he knew it must be the ghost of his dead wife. The third night, exasperated, he finally responded to the voice "What floats? And the voice said "IVORY SOAP!"

  • Jane Austen's books, which define the Regency Romance subgenre.
    • Pride and Prejudice is used on the Period Piece page to illustrate a story whose crisis could not occur in a present-day 21st century setting.
    • Northanger Abbey was actually this at the time of publication, being an early work of Austen's only published later in her lifetime, and being a send-up of the Gothic Horror novels which were popular when it was written; however, tastes had since moved on. The author even issued an apology for this in the preface.
  • Stephen King's works are chock full of pop-cultural references from whenever the book was written, to an almost Family Guy-like extent. It helps that he tries to keep things timeless by heavily reference-mining 1950s and '60s pop culture, but that in itself evokes the poignant Baby Boomer nostalgia that was everywhere in the '80s when King wrote many of his most iconic novels.
  • Dan Simmons' Hyperion Cantos series (taking place some hundred years into the future) is filled to the bursting with reference to 20th century culture. There are a few older references and a few references to fictional future events, but the overwhelming majority of them are from Simmons' lifetime.
  • While the James Bond novels fall into this when it comes to fashions and attitudes, Ian Fleming went out of his way to avert this somewhat with the introduction of SPECTRE in the later books. By using a strictly apolitical organization to replace SMERSH as the main evil group, he intended for the books to avoid being too firmly entrenched in the Cold War culture in which he was writing.
  • P. G. Wodehouse's books took place in a kind of flexible Comic-Book Time version of the Genteel Interbellum Setting that he originally began writing them in, and he kept them coming until his death in the 1970s. In one interview, he noted with bemusement that he was was writing "historical novels".
  • The Nancy Drew and The Hardy Boys books, which have been written non-stop since the late 1920's, always give an interesting cross-section of culture at the time. The originals actually had to have their very 20's sensibilities modernized during the 60's, where it happened all again. It got worse after they switched publishers in 1979, since the new publishing house was a lot more prone to using much more topical themes. Two 80's spinoffs, The Nancy Drew Files and The Hardy Boys Casefiles, had stories taking place in very 80's settings, such as on a soap opera (at the peak of General Hospital supercouple Luke and Laura) or horror movies (back when Friday the 13th and Nightmare on Elm Street were churning out sequels left and right). Similarly, the most recent series, Nancy Drew: Girl Detective and Hardy Boys: Undercover Brothers, are even moreso, with stories about reality TV and cyberbullying.
  • Some of Bill Bryson's travelogues; In The Lost Continent Bryson is startled to see how much America had changed since The '60s. Reading it today is reveals how much the country has changed since 1987-88. It's certainly one of the last works to mention strip clubs in Times Square; similarly in Neither Here Nor There Bryson discovers how much Europe has moved on since he backpacked around as a student in the 1970s. Being written in 1990 it has a pre-single European currency Europe and a pre-Balkan war Yugoslavia, pre-Oresund Bridge Denmark, as well as relying on printed guidebooks for European train times; A Walk in the Woods the Gizmo-crazy hiker is kitted out with technology that was advanced in 1997 (GPS, self-pitching tent) but is fairly standard fare now; Notes from a Big Country mostly deals with a mid-90's world just before the internet and cellphones became ubiquitous - Bryson mentions the difficulty of finding change for a payphone at the airport, the amount of mail order catalogs he's sent, sending faxes to the UK, and renting movies on videotape.
  • In general, many encyclopaedias and other books of knowledge often end up quite dated as knowledge updates itself. Theories that were at one time new and controversial become commonplace and one-common knowledge becomes discredited, meaning any encyclopaedia more than about ten or twenty years old show their age.
    • As referenced in The Discworld Companion, Terry Pratchett believed that books a century old are useful as historical documents while textbooks a decade old are unreliable because you don't know what you're missing. In fact, The Discworld Companion itself also applies, with the original edition released in 1994, restricting it to barely half of the books in the series, and the most recent edition was released before the final two Discworld books were published.
  • An entire genre of books known back then (with only the Dutch term still surviving) as "De Karelroman" (Elegast being the most popular example). Part of their appeal was that medieval celebrities such as Charlemagne were in the main roles of a story that sounds pretty similar to the fairy tale. Add in such infamous morals such as that you must be loyal to your lord and you get an example of a trope that is Older Than Print.
  • Dracula has a bit of this as Mina scoffs at the whole fad of the "new woman" culture which was arising in London at the time focusing on women becoming more independent. Course Stoker is using it as an allegory to the subject including being more sexually forward which likewise ties to vampirism and it lack of morality as demonstrated by the count's vampire brides earlier in the story. Although this is often pegged as Hypocritical Humor; Mina is by far the most proactive and competent of the hunters and every time the party tries to restrict her to a traditionally feminine role it backfires horribly.
  • Harry Potter plays with this trope. The first four books were written between 1990-1997, while the last three books were written between 2000-2007. However, they are appropriately set in the 1990s (1991-1998, specifically), since that was the time Rowling did the most writings. In addition, the books proper generally avoid using references to the real-life pop culture of the 1990s. An In-Universe explanation is simple: The Wizarding World lives a different lifestyle from that of the Muggle world by using medieval technology, and most wizards don't understand Muggle culture and technology. Furthermore, the Wizarding World is too busy worried about Voldemort to name drop 1990s pop culture anyway.
    • A prominent exception to this is when Harry mentions to Sirius about how the former's cousin Dudley broke his Play Station in the fourth book (which was written in 2000). In real life, the PlayStation came out in Europe on September 9, 1995 - over a year after the events of the In-Universe correspondence (the summer of 1994). There are two possible explanations to this: Either the Dursleys bought an early version to appease their son's desires, or Harry might have confused it with a similar console.
  • In the mid-2000s, Hard Case Crime re-released some of the first novels that Michael Crichton had published under the pseudonym "John Lange" in the 1960s. In one case, they tried to get over Technology Marches On and Society Marches On by adding bookends with an elderly version of the main character telling the story to his grandson... who is filming him in DVD with a videocamera. As a result, the novel is now only unintentionally dated to the mid-2000s.

    Live Action TV 
  • Quite unavoidable with a Long Runner such as Doctor Who — the special effects and fashions give the production decades away within minutes. When the stories have been restored to DVD with new special effects, the Restoration Team have very deliberately shot many of the new effects in appropriate styles so they wouldn't clash with the source material. So the Five Doctors Special Edition has new and improved CGI effects that actually look like Eighties effects.
    • And once again used deliberately in "Time Crash", which alternates between the grand orchestral score of the Tenth Doctor's era and the the synthesized background music of the Fifth Doctor's era.
    • Watch's 50th Anniversary rundown of the Doctors pointed this out while discussing each Doctor - pointing out how each Doctor's personality, the personality of the threats they faced, and especially their personal appearance was informed by the era from which they came. For instance, the narrator suggested that the addition of Mel was inspired by the 1980s fitness craze, and most of the talking heads seemed to agree that, while Colin Baker's outfit was incredibly awful even in-universe, it's really only a mild exaggeration of hideous things people sincerely wore in the 80s.
    • Played with in the novelization of "Shada", which was a 1979 Development Hell episode originally written by Douglas Adams,note  and eventually novelized by a writer on David Tennant/Matt Smith-era Doctor Who in 2012. As a result, the 1970s setting, which was Like Reality Unless Noted for Adams, is deliberately played for kitschy absurdity - the male companion is specifically noted to have long, feathered hair and a taste for denim jackets (which would have been assumed default in the '70s), a very Douglas Adams joke about humanity's obsession with digital watches goes from being satirical (similar to a modern joke about fixation on smartphones) to being funny entirely because of the anachronism of it, and the band Status Quo show up at one point, for laughs. At the same time, the Time Lord tech is altered to be more like modern tech, with K-9 being given a battery charge indicator that works like one on a modern phone, and Chronotis's time telegraph having a touch screen and a 'Sent Mail' folder, and it's likely this was intended to look equally silly in the future.
    • The first revival season ends up falling into this thanks to hefty amounts of We're Still Relevant, Dammit, much of which relaxes once the series became a confirmed hit. The Tylers' (and a few other characters') Chavvy fashion style is significant, Rose has to visit her boyfriend's house to use the internet (which is a mixture of Timecube-esque personal sites and Livejournal) and uses a Nokia brick phone which is nevertheless talked up, homosexuality is discussed in slightly edgy pre-civil-partnership terms.

      The second story involves Britney Spears' "Toxic" as 'a traditional Earth ballad', the fourth is a Whole Plot Reference to 9/11 conspiracy theories and the 'sexed up' Iraq September Dossier, and the finale is about the Doctor (and the Daleks) getting trapped in Deadly Game versions of 2005 light entertainment shows, like The Weakest Link, Big Brother and What Not to Wear, complete with celebrity parodies immediately recognisable to the contemporary audience but rather dated now. (There was a certain Reality Subtext to this last part, as the main feeling in the television industry was that the Doctor Who revival was doomed as 'family television' didn't exist as a format any more except in the form of Soap Opera and reality or game shows.)
    • In "The Time Meddler", The Doctor discovers that The Meddling Monk is not from The Middle Ages (but from the distant future)... because he uses a record player to re-enact the sound effect of Monks praying.
    • Classic DVD releases all come with a little booklet which gives some details about the story in question. However, some of the "facts" within them are no longer true. The booklet for The Romans (Released 2009) talks about the current incarnation of the Doctor, a man who is now two Doctors ago. The Lost In Time set (Released 2004) claims there are 108 missing episodes, when actually there are now only 97. Arc of Infinity claims that Colin Baker is the only person to be in Doctor Who before being the Doctor, which Peter Capaldi may now disagree with.
  • Soul Train: Mainly for The '70s, but also for The '80s and The '90s.
  • Thanks to the Ripped from the Headlines formula, Law & Order, depending on the season, can seem quite dated. On the other hand, the fact that they just switch the names makes it so that the older episodes can still be enjoyed on their own merit.
  • Episodes of Saturday Night Live, thanks to its musical guests and its use of topical, current events humor (from "Generalíssimo Francisco Franco is still dead" to "I can see Russia from my house!"), can be dated almost to the year.note 
    • Parodied in the opening monologue of an episode hosted by John Goodman, with musical guest Tom Petty and The Heartbreakers, who both made most of their many appearances in the '90s.
    • The Franco one was called back when Chevy Chase hosted and appeared on Weekend Update along with then-host Kevin Nealon, using 1975 news-jokes who Nealon immediately complained about afterwards.
  • Pretty much every Game Show is dated to the year that it's produced, whether because of the products (four-figure Datsuns, anyone?) or the questions (which can fall prey to future updates).
    • Other times, they will have answers pertaining to then-current pop culture, which may or may not fall under this trope depending on how long-lasting that pop culture item becomes. For instance, an answer on a 2003 episode of Wheel of Fortune was LIFE WITH BONNIE, a short-lived ABC sitcom that is barely a footnote in Bonnie Hunt's career.
    • Commented on in Where In The World Is Carmen Sandiego. The Chief would always read a disclaimer at the end that all geographical information was current as of taping. Given that the show's run coincided with The Great Politics Mess-Up, The Yugoslav Wars and a number of other events, all of which meant that any given day an atlas may have become obsolete, it makes perfect sense. It's possible that the follow-up show, Where In Time Is Carmen Sandiego, switched its major topic from geography to history for that very reason, since history is, by definition, one of the few subjects that would be immune to change from current events.
    • Even Rockapella's theme song had to change with the times; After the '93 season, Carmen no longer traveled from Chicago to Czechoslovakia, but to Czech AND Slovakia. And back.
    • One episode of Britain's Strike It Lucky led with an admission that they were out of date; the answer to one of the questions had changed during the week it aired.
    • Invoked with The Challengers, which stated the airdate at the beginning of the episode, and taped a week of episodes on Friday to be aired over the following week, in order to use extremely contemporary material. However, the show only aired from 1990-91.
  • Happens a lot more in Star Trek than you would think at first glance. The more obvious examples are of how Kirk's Enterprise looked, essentially, like a 1950s-60s naval vessel in its design and style, and how Picard's Enterprise was comparatively bright and pastel, just like the decade in which it was envisioned, but more glaring is the almost total lack of anything resembling pop culture in the Star Trek universe from after the end of the second millennium. Everybody listens to jazz and classical music, reads classical works of literature or, at most, stuff like pulp or noir, enjoys classical plays, and the most popular games seem to be variants of ancient games such as chess or racquetball. Movies, television and video games are practically non-existent, the writers never saw the internet coming, and there are scant examples of any post-20th century media. It's as if human culture essentially stopped after a certain point, even as Technology Marches On.
  • Episodes of The Price Is Right from the 20th century often included outdated technology such as VCRs and phonographs, the vehicles offered during the 80s BLED then-contemporary structure and design, and showcases often included pop music from the 80s. At one point the Giant Price Tag was very, VERY 80s, featuring the show's logo on a Space/Futuristic background. As the contestants were always pulled directly from the audience, the fashions and cultures of the 70s and 80s were very prevalent.
    • Price actually stayed stuck in the 80s well into the early 2000s, given their insistence on using physical props instead of video monitors, a set that went mostly unchanged for 20 years, and of course, the prominent use of Edd Kalehoff's Moog synthesizer in their theme song (it's still there, by the way).
  • British panel show Never Mind the Buzzcocks falls into this, with many of the show's jokes referring to subjects topical at the time, many of the songs being referenced falling out of vogue a couple of years or so after the episode's original airing and having numerous guests who ended up becoming One Hit Wonders. (In the case of the latter, some of these guests had already become obscure by the time they appeared on the show.) As well as this, the theme song changed with the times, to an indie-style version of itself in 2006.
    • For example, the first episode (made in 1996) had the drummer from Dodgy as one of the guests (the band faded into obscurity in the late 90s) and one of the intros was "I Love, You Love, Me Love" by Gary Glitter who didn't have a joke made at his expense. note 
    • A more recent example would be the times Simon Amstell mocked Amy Winehouse's alcoholism.
  • Pick any long running Toku franchise, and you'll probably be able to guess the decade from the fashions alone. For example...
    • Ultraman is most definitely a product of the 60's, if only for tone. While it still had many of the super science trappings of the late 50's, its tone of hope for the future and building a better tomorrow are more in line for what 60's Toku was becoming.
    • For that matter, many of the Ultra series date themselves through aesthetics alone, with hippies showing up in both Ace and Jack, and an early seventies Psychedelic Rock song in one ep of Return of Ultraman.
    • The first five Kamen Rider series (Kamen Rider through Kamen Rider Stronger) are essentially products of the 1970's, given the heroes' fashions.
      • Kamen Rider Super-1 also manages to date itself through both clothing and background music, as well as the fact that Super 1's bike is a reference to Chips.
    • Super Sentai and by proxy Power Rangers have tendencies to appear dated to the year they came out depending on the season's clothing, hairstyles and technology; especially those used by the heroes.
  • The producers Freaks and Geeks avoided the tendency of teen shows to fall into this by making an intentional period piece, setting the show in 1980-81.
  • A lot of sketch comedy shows end up becoming this (examples include Saturday Night Live, Chappelle's Show, Mad TV, and In Living Color!).
  • The Inspector Morse episode "The Wench is Dead" can instantly be dated to the mid-1990s when Adele Cecil makes a telephone call from a public booth, using a prepaid card. A few years earlier, she'd have used cash; a few years later, and she'd have been carrying a mobile phone.

  • Music videos tend to date themselves very quickly, especially videos by female artists, since women's fashions change more quickly than men's. Go look at a video like En Vogue's "Free Your Mind" and see whether it doesn't scream 1992 (a big hint is a "blink and you'll miss it" shot of one guy's shirt referencing the 1992 L.A. Riots).
  • Many, but not all, political songs fall into this category. To name a few:
    • Gil Scott-Heron's The Revolution Will Not Be Televised ripped into many popular culture icons, advertising campaigns and public figures from 1971, when the song was released.
    • Songs about apartheid rule such as Free Nelson Mandela by Special A.K.A. Just 6 years after the song was released, Mandela was released from prison.
    • Elvis Costello's Oliver's Army, which name-checked various places that were geo-political hot spots in the late 1970s.
    • Just about any song about The Vietnam War.
    • Heaven 17's Fascist Groove Thang is firmly planted in the year 1980, due to mention of Ronald Reagan as 'President Elect'.
    • Much of the references in political 1980s hardcore punk like Dead Kennedys ("Holiday in Cambodia") and Minutemen ("Viet Nam", "West Germany").
      • Astoundingly, the Dead Kennedys' "California Uber Alles" was suddenly relevant again when Jerry Brown was re-elected California governor about 30 years after the song was recorded.
    • John Rich's "Shuttin' Detroit Down" protested the government bailouts of General Motors in 2008-09.
    • Darryl Worley's "Keep the Change", a 2010 song ranting against the second Obama administration.
  • It is the tradition in Trinidadian Calypso to sing about about current events such as politics, news stories, and other calypso singers who are popular at the time. As a result, old calypso is a great time capsule into whatever period it was recorded in.
  • Each of "Weird Al" Yankovic's albums is largely a product of the year it was recorded, as Al fills the albums with parodies of popular music at the time or older songs parodied in a way that references current pop culture:
    • His self-titled debut album from 1983, despite being a case of Early Installment Weirdness, is composed of power pop, bubblegum, heartland rock and early New Wave, also mentioning discotheques and 8-tracks which were fading at the time of its release.
    • In 3-D, Dare to Be Stupid and Polka Party from 1984/85/86 are composed mostly of New Wave, over-the-top electropop and bar rock.
    • Even Worse and UHF: Official Motion Picture Soundtrack and Some Other Stuff from 1988/89 are composed of arena-oriented dance pop, hair metal, hip hop and teen pop.
    • Off the Deep End and Alapaoolza from 1992/93 have heavy metal, hip hop, dance pop, jangle pop with single Nirvana and New Kids on the Block parodies symbolizing both the rise of grunge and 80's teen pop acts taking their dying gasp.
    • Bad Hair Day from 1996 is composed of hip hop, alternative rock, grunge, college rock and R&B.
    • Running With Scissors from 1999 is composed of hip hop, bubblegum pop, adult contemporary, alternative rock and country, with a parody of "Zoot Suit Riot" by the Cherry Poppin' Daddies symbolizing the era's neo-swing revival, and a parody of "American Pie" by Don McLean which recapped the then-new Star Wars film The Phantom Menace.
    • Poodle Hat and Straight Outta Lynwood from 2003 and 2006 are composed of hip-hop, ringtone rap, punk rock, emo rock and R&B, with some ribbing of popular American Idol launched acts thrown in.
    • 2011's Alpocalypse is composed of hip hop, dance pop and bubblegum teen pop. In addition, the album's title is in reference to the 2011 and 2012 doomsday predictions.
    • 2014's Mandatory Fun could almost be seen as Early 2010s Pop Culture: The Album. Noteworthy are the song "Tacky", with its references to Instagram, Yelp, selfies, the YOLO (You Only Live Once) motto, and twerking, and the fact that there's even a song on there entitled "First World Problems".
    • Pre-Mandatory Fun, Al was a bit of an odd case - he tended to parody songs that were popular two or three years before his album came out, which means they were usually forgotten by the time his parodies were released. This was the inevitable result of recording times, and is the chief reason Al will no longer record physical albums after the aforementioned Mandatory Fun. Instead, Al will turn to digital-only releases, with digital recording techniques and distribution speeding up the release process considerably. This was even seen as such with his parody of Lady Gaga's "Born This Way", "Perform This Way", which was released digitally only a couple of months after the original song.
      • The fact that his albums generally contain parodies of songs or pop-culture fads that are a year or two old by that time does help the age factor slightly, though. Years ahead people recognize his albums as summaries of the era they were made in instead of hits based off a specific year.
    • "I Lost on Jeopardy" is a double example. Besides relying on a song over a year old ("Jeopardy" by The Greg Kihn Band), the music video parodies the original 1964-1974 version of Jeopardy!, complete with cameos from original host Art Fleming and original announcer Don Pardo… all a mere three months before the current version of Jeopardy! (hosted by Alex Trebek and announced by Johnny Gilbert) debuted.
    • "Biggest Ball of Twine In Minnesota" could easily stand in for any time period for the whole song... until the single line "In our '53 Desoto". That car was aged but reasonable in the 1980's, but now you wonder why he'd be driving that ancient museum piece.
      • Similarly, the car that keeps getting impounded in "Stop Dragging My Car Around" is a '64 Plymouth, obviously Rule of Funny in 1983 but applies now since they don't make Plymouths anymore.
    • "Headline News", from 1994, arguably and intentionally takes this trope Up to Eleven. Like "I Lost on Jeopardy", this was based on a year-old song ("Mmm Mmm Mmm Mmm" by Crash Test Dummies), but here, Al replaced the three bizarre stories of the original with three (arguably equally-bizarre) tabloid news stories that were prominent that year. In song order: Singapore caning American delinquent Michael Fay, the attack on figure skater Nancy Kerrigan by associates of her rival Tonya Harding, and Lorena Bobbitt severing her husband's... weiner with a knife.
    • Al's polka medleys also fall under this. Each album (save for his debut and 1988's Even Worse) features one, and nearly all of them are a medleys of recent hit songs of their respective eras (his first, "Polkas on 45", also contained songs from the '60s and '70s mixed in with recent '80s hits). The lone aversion of this trope is "The Hot Rocks Polka", which is comprised entirely of The Rolling Stones songs (none of which are from the '80s; the latest two songs in the medley, "Miss You" and "Shattered", had been released in 1978).
  • Also true of other parody artists. For instance, Cledus T. Judd's first few albums usually parodied country songs from the past two years, sometimes going back even further (his first album in 1995 had spoofs of "Hotel California" and "We Are the World", while his second parodied "Jackson" and "The Devil Went Down to Georgia"). By 1999, his turnaround was a bit quicker, to the point that his fourth album spoofed "Livin' la Vida Loca" only five months after that song's release. Later albums zig-zagged this, with some parodies ranging from only a few months after the original's release to two or three years. But probably his quickest examples came on 2012's Parodyziac!!, where Little Big Town's "Pontoon" was parodied less than two months after it hit #1, and Eric Church's "Creepin'" was parodied while it was still on the charts.
    • Another example is "Martie, Emily & Natalie", which was a timely takeoff of Brad Paisley's "Celebrity" that spoofed the Dixie Chicks' fall from grace in early 2003. The original had a reference to The Weakest Link which was dated even then. But the whole song's datedness was only exacerbated when it made a repeat appearance on Bipolar and Proud a year later (likely because the original was on a limited-release EP).
  • In 1996, the GrooveGrass Boyz parodied the "Macarena" in country form. That's in no way a period piece.
  • Most of those CD compilation albums that are released every year, such as Kidz Bop or Now That's What I Call Music! become this within a few years of being released, because they are just compilations of the top hits of the year.
  • Obviously The Beatles have proven to be timeless, but the Moog synthesizer that shows up on a few Abbey Road songs is a little jarring (primarily on "Because" and "Maxwell's Silver Hammer"; it's slightly more subtle on "Here Comes the Sun" and used only to make noise for the crescendo of "I Want You (She's So Heavy)"). What was considered a cutting edge musical innovation in 1969 went on to become the definitive sound of 1970s cheesiness.
    • To be honest this is quite true of much music that makes a lot of use of synthesizers, up to at least The '80s (heck, especially The '80s!) due to the way the technology has evolved.
    • And on the subject of The Beatles, whilst their appeal is certainly timeless, given they're one of the foremost bands to define The '60s, they do after a fashion play this trope straight - albeit in a positive sense, rather than the negative "hasn't aged well" sense. Their songs themselves vary in this - some almost deliberately evoking a timeless feel, some very much of their time, in retrospect.
  • Whenever a Gaita Zuliana group decides to tackle a current issue, it instantly dates itself. This is not only on political songs, but also with mundane themes. "La Parabolica (The Parabolic Antenna)" for example, is still being played, despite being firmly root on its launching year of 1987, three full years before Cable TV arrived to Venezuela rendering most of its complains (like all the programming being on English or its enormous size) instantly obsolete.
  • If you want an earful and eyeful of most of the defining mainstream music trends from The '60s through the Turn of the MillenniumFolk Rock, Heavy Metal, Glam Rock, Funk, Krautrock, New Wave Music, Pop rock, Hard Rock, Electronica, Alt-Rock, with a few other styles thrown in for good measure — just follow the bouncing Bowie, who helped define some of them in the first place.
  • As a Long Runner, Ray Stevens has done this many, many times in his career.
    • 1970: "America, Communicate with Me". It's clearly a song bridging the gap between the '60s and '70s, as the line "Three small bullets took the leaders that could help us all unite" addresses the assassinations of John F. Kennedy, Robert F. Kennedy, and Martin Luther King Jr., and snippets from an interview with actual late '60s protesters are heard in the opening.
    • 1974: "The Streak", about the then-popular craze of streaking, because Naked People Are Funny. Sure, some people still do it today, but the 1970s was its peak.
    • 1974: "Moonlight Special", a five-minute parody of The Midnight Special, a very '70s variety show. His take on it includes parodies of Gladys Knight & the Pips, Alice Cooper, and Jerry Lee Lewis.
    • 1986: "The People's Court", a five-minute parody of, well, The People's Court that name-drops original judge Joseph Wapner (who left the show in 1993).
    • 1987: "Would Jesus Wear a Rolex" is a Religion Rant Song against the many controversies present in televangelism at the time. Of course, the "megachurch" movement in American Protestant Christianity is still relevant today, and arguably much more so. But it was an astonishingly new phenomenon in the '80s, whereas nowadays it's become such a commonplace element of America's religious culture that the media doesn't bother to cover it that much anymore.
    • 1991: "Workin' for the Japanese" is a (surprisingly vicious by his standards) mockery of the insurgence of Japanese products in the American market in the early 90s.
    • 2001: "Osama— Yo' Mama": A post-9/11 mockery of you-know-who.
  • Fearless Records' "Pop Goes Punk" albums use rock cover songs of pop songs that are popular in the year that the album was released. Not only do the songs differ, but so do the styles of the bands covering them. Earlier albums released in the early-mid 2000s have more pop-punk and emo-flavored bands while later albums from the late-2000s and early 2010s rely on metalcore and scenecore bands. Even if the albums focus on a specific style or period, such as the two "Pop Goes '90s" albums from 2006 and 2014 respectively, they're still in the style popular in the time those albums were released.
  • The Bellamy Brothers:
    • Their 1985 hit "Old Hippie" has the titular character turning 35 and disco and new wave leaving him cold in the first. A 1995 sequel, creatively titled "Old Hippie (The Sequel)", has him turning 45 and name-dropping Billy Ray Cyrus and Garth Brooks and mentioning President Bill Clinton as well as Woodstock '94. Subverted by the fact that fans of all ages (even those who turned 35 long before the hippie era or were born after it) completely identified with the song's central idea.
    • 1987's "Kids of the Baby Boom" centers itself on people of the same generation a bit more lightheartedly ("We all grew up on Mickey Mouse and hula hoops / Then we all bought BMW's and new pick-up trucks / And we watched John Kennedy die one afternoon... Kids of the Baby Boom").
    • 1994's "Not" uses the Not trope popularized by Wayne's World a few years prior.
    • And from 1999, "Don't Put Me in the Ex-Files", of course makes a pun on the title of the then very popular The X-Files.

    Newspaper Comics 
  • Averted for the most part in Calvin and Hobbes but a few 80s and 90s references have popped up. The strip has mentioned VCRs, records, New Wave fashion trends, Siskel & Ebert, the Cold War, and The Dark Age of Comic Books, making the strip appear somewhat dated.
    • Some of this was Enforced. Watterson noted that Calvin's household had a few appliances such as a rotary phone and a TV with dials rather than buttons which were considered outdated even back then, but he drew them anyway because he felt they had more personality.
    • One 1989 storyline had Calvin locking his babysitter, Rosalyn, out of the house at a time where virtually no teenagers carried cell phones with them. If the arc was published today, Rosalyn could call Calvin's parents and put a quick end to his night alone.
    • Several strips feature Calvin answering the home landline humorously. The phone is on a cord with no answering machine.
  • FoxTrot gets most of its humor from technology jokes and pop culture references, making much of its older strips very dated.
    • A 1990 Story Arc features the Fox family getting a compact Macintosh computer (while never explicitly stated as such, it appears to be a Macintosh Classic).
    • One comic has Jason dress up like an iMac for Halloween. When Peter asks why that would be scary, Jason replies "I have no floppy drive!", terrifying Peter. Most modern computers don't have a floppy drive, as floppy disks have been replaced by CDs, DVDs, and downloads.
    • In a January 1993 strip, Jason dreams that he found a Macintosh Quadra 950 with 64 megabytes of RAM and 230-megabyte hard drive as a Christmas present he forgot to open. A typical computer now has its memory measured in gigabytes, even terabytes.
    • The strips where Jason shows enthusiasm for The Phantom Menace, thanks to the severe Hype Backlash.
    • This strip has Jason dress up as George Lucas for Halloween, saying that it's horrifying that Lucas plans to release all the Star Wars films in ThreeD. Two years after the strip was made, Lucas sold the Star Wars franchise to Disney, who discontinued the project in favor of releasing new movies, such as The Force Awakens, leaving The Phantom Menace as the only one converted to 3-D.

    Professional Wrestling 
  • Pro wrestling has traditionally tried to avoid this, not because it would cause their matches to become dated (only since the age of television have the matches actually been recorded for posterity, the wrestling companies pride themselves on never showing reruns, and much of the match's story content is pretty interchangeable anyway), but because wrestling is supposed to exist in its own peculiar fantasy world of Kayfabe, and allowing too much of the real world to seep through would spoil this illusion. At least, that was the case until the late 1990s, when the WWF (and, to a lesser extent, WCW) developed a South Park-like fascination with "hip" topical humor, such as openly mocking the Bill Clinton/Monica Lewinsky scandal, or airing a fake home movie called The Blonde Bytch Project. Things have only gotten worse since then, with WWE whipping out the We're Still Relevant, Dammit card every chance they can get; the low point was probably Vickie Guerrero parodying Clint Eastwood's addressing of an empty chair at the 2012 Republican National Convention, which 20 years from now will make even less sense to kids than Nikita Khrushchev banging his shoe on a table.

    Tabletop Games 
  • A trivia game published in the 1980s with "West Germany" as an answer is moot because that country no longer exists by itself anymore, having reunited with East Germany.
    • Trivia games in general can fall into this. Aside from political changes like The Great Politics Mess-Up, many are pop culture based, or have pop culture categories, and make no sense to someone just a few years out of the original audience. Plus, what was obscure trivia when the game was published might be common knowledge a few years later (like the fate of Apollo 13 before and after the release of the movie). And that's ignoring cases of Science Marches On, Dated History, and other things that can make the "correct" answer just plain wrong.

    Theme Parks 
  • The Terminator 2 3-D: Battle Across Time performance at Universal Studios theme parks, specifically the pre-show, which talks about all of the fascinating new technologies that Cyberdyne is working on. Problem is, it first opened in 1996, and has not been updated in the intervening years. Most people watching this pre-show probably have smartphones in their pockets and purses, and various gadgets in their homes, that can put to shame the "advanced" computers and robotics on display. To say nothing of the cameo by Shaquille O'Neal. Universal eventually closed the attraction at the Hollywood park in 2012 partly for this reasonnote ; it's still open at the Orlando and Japan parks for anyone who wants to make like Kyle Reese and go back in time twenty years.
  • The now-closed Jimmy Neutron's Nicktoon Blast first opened in 2003, meaning that it represented the Nickelodeon of that time, with the likes of the Rugrats, Hey Arnold!, The Wild Thornberrys, and the classic Nickelodeon splat logo being in it. Therefore the ride started becoming this as early as 2006 and really became this in 2010.
  • E.T. Adventure is the oldest ride still remaining at Universal Studios Florida and for the most part is largely unchanged from what it was when it first opened. As a result, the ride definitely carries a serious "90's" feel to it, with its dated animatronics and effects.
  • Tomorrowland at Disneyland got hit with this twice during its lifespan. The original park's Raygun Gothic vision of the future became outdated within just a decade, causing them to start making updates to the park over the course of The '70s and The '80s. "Flight to the Moon", for instance, became "Mission to Mars" after the Apollo landings. Of course, by The '90s these visions of the future were also outdated.note  In 1998, the Disneyland designers finally threw up their hands and embraced Tomorrowland's Zeerust, redoing it as a retro-future area inspired by classic sci-fi and Eurodisney's Discoveryland.
    • They did get some things right, though. Most notably, the original 1955 imagining of the "future" of 1986 envisioned a no-nonsense, utilitarian design for spaceships and the like - and, come the actual 1986, that aesthetic was indeed popular for sci-fi, especially for children's toys. It certainly looked a lot more timeless than, say, 1970s predictions of what the future would look like (just try to imagine Tomorrowland if Disneyland had opened in 1974, and recoil in horror).
  • Because Science Marches On and Technology Marches On, virtually all of Future World at Epcot — which opened in 1982 and was devoted to predicting the 21st century — has been substantially updated and even replaced over the years. Much as nostalgic Disney park fans miss Horizons, World of Motion, CommuniCore, etc., it's telling that they were replaced with attractions that are easier to update and/or have more appeal to children. (An entire pavillion, Wonders of Life, was shut down because it just couldn't keep up with health and medicine marching on.) Attractions that haven't been overhauled in more than a decade (the Universe of Energy/Ellen's Energy Adventure show, for instance) get called out for falling into this trope. And when Captain EO was revived in 2010 due to popular demand, it served to prove that no matter what Michael Jackson fans might think, '80s Hair, synthesizers, and neon-colored aliens and backup dancers are not timeless (though certainly a lot of fun).

    Video Games 
  • Due to Development Hell causing the game to be delayed continually since its inception 13 years prior to its release, Duke Nukem Forever (released in 2011) has the unintended disadvantage of playing as though certain parts were only added in a certain year when they were the latest trend in gaming. The gameplay borders on Genre Roulette as it tries to mimic late-90s cornball camp shooters, early-2000s dark sci-fi shooters with frequent, lengthy turret sections, and late-2000s grim realistic shooters practically in sequence - Zero Punctuation noted that "you could practically cut it in half and see the entire fourteen years of shooter evolution it's tried to keep up with, like the rings in a tree stump" - the humor is outdated by several years, the references to previous installments are years (and even decades) out of date, and as a whole the game is much slower-paced than 2010-era FPS's. In addition, several of the "topical references" include Expies of the Olsen Twins (last relevant in 2004), an out-of-date Take That directed at Halo (height of the Master Chief's popularity was in 2007), a quickly-killed character named after Leeroy Jenkins (a resilient joke, to be sure, but one from 2005), and a near-exact replication of the infamous Christian Bale rant from the set of Terminator Salvation (already fading by late 2009). Because of this effect, the mechanics that were added more recently (Regenerating Health, Duke only being able to carry two weapons at once) stick out like a sore thumb instead of "making the game to today's players".
  • League of Legends has a character skin dedicated to the Giant Enemy Crab, a meme from 2006. The game is still going strong a full decade after the meme and at this rate looks like the last thing on earth that will recall the meme.
  • This also occurs with works that don't make real world references. In the Super Mario Bros. spin-offs of the early to mid 2000s, there would always be elements from the then-latest main game, Super Mario Sunshine, which were not retained in later Mario games. Notably, there was an undercurrent of the games being set in the tropics rather than in the Mushroom Kingdom, which was dropped in the Wii era with the release of Super Mario Galaxy.
  • The various games in the Grand Theft Auto series have had this happen to them. Vice City, San Andreas, and the Stories games, on the other hand, averted this by being intentional period pieces to the '80s and '90s.
    • Grand Theft Auto III is supposedly set in Autumn 2001, when many aspects of both the late '90s and the early '00s, such as the dot-com boom, massive SUVs, boy bands, the infancy of Reality TV, and the rise of the Cell Phone (the main character still uses a pager), were easy topics to explore and satirize. Although the game was released two months after 9/11, very little was changed to reflect thatnote , and as such, the atmosphere of the game is more grounded in the immediate pre-9/11 period of 2000-01 than later.
    • Grand Theft Auto IV is set squarely in then-contemporary (2008) New York, and when played in the current decade, becomes this to the mid-late 2000s. There's the obvious use of contemporary music and vehicles, but it also extends into the political and cultural satire. The economic crisis was just starting to sting (especially in the expansion pack The Ballad of Gay Tony), but the President was still the cowboy from Texas rather than the professor from Chicago, and much of the satire was directed at such targets as The War on Terror and the then-politically empowered Christian Right. Its portrayal of New York is less The Big Rotten Apple like in III and more a gentrified, nanny-state Theme Park Version of itself with a yawning gap between the rich and the poor, reflecting how stereotypes of the city had evolved during the mayorship of Michael Bloomberg. The shadow of 9/11 (or at least the GTA universe's fictional version of it) hangs heavily over the city; the bridges to Algonquin and Alderney are closed initially due to perceived terrorist threats (leading to hand-wringing from Weazel News when they're re-opened), the Patriot Act and the now-discontinued terror alert system come in for ribbing, and there's a massive construction site in lower Algonquin that's strongly implied to be where Liberty City's version of the World Trade Center had once stood.

      The technology present is also particularly dated. The protagonist Niko uses a big, chunky black cell phone with a monochrome screen for most of the game, with the color-screen camera phone he receives halfway through the game treated as a luxury item. (Smartphones are never even mentioned.)note  The in-game Internet is filled with parodies of MySpace, Yahoo!, Jamster, YouTube (back when they were first getting embroiled in DMCA takedown controversies), Napster, Second Life, World of Warcraft, and many, many Geocities lookalikes, and is most conveniently accessed by way of Internet cafés, which were already on the way out by the time the game was released.
    • And of course, there's Grand Theft Auto V, set in Southern California circa 2013. It's the height of the Great Recession; the first teaser for the game prominently showed a "foreclosure" sign being put up in front of a house, as well as homeless people living in tent cities under Los Santos' overpasses, and in the finished game, one can find a "dignity village" in the northern part of the map that contains a lot of imagery lifted from the Occupy movement. Simeon's business also exploits people who try to keep up with the Joneses by using cheap credit to live beyond their means, a clear reference to one of the main causes of the recession. The technology has advanced with the times; all of the main characters, even the white-trash Trevor and the gang banger Franklin, have smartphones with full internet access, and on that internet, one now finds parodies of Twitter, Tinder, Kickstarter, and most notably Facebook, whose CEO and headquarters actually show up in the game in a vicious Take That at contemporary Silicon Valley tech culture. (Fittingly, it has rendered the aforementioned MySpace parody Deader Than Disco.) Beyond that, the in-game media is filled with parodies of such early '10s touchstones as Fifty Shades of Grey, Call of Duty, the New Atheism movement, and the push for marijuana legalization.
  • Night Trap – a side-effect of having the footage shot in the eighties (it shows) and releasing it in the nineties after the hangover(s) from the previous decade have worn off.
  • Any racing or driving game that features real cars is doomed to finding itself dated by virtue of technology marching on. The cutoff date for the cars appearing in the game becomes more obvious the further the game falls into the past; the modern cars in some of the PS1 Need for Speed or Gran Turismo games are now almost old enough to be considered antiques. (And in some cases, they already are; the first Need for Speed had the very '80s Ferrari Testarossa, the third had the equally '80s Lamborghini Countach, and neither felt particularly out of place next to the other cars!) It makes for a great time capsule of what were considered Cool Cars in the time the game was released; if some of those cars have since fallen into obscurity, or (in the case of the concept cars that often featured) never even seen the light of day, all the better. Even games that use fictional vehicles (such as the Burnout, Grand Theft Auto, and Saints Row series) can fall into this trap if the cars in question are closely-enough based on contemporary cars and styles.
  • Sports games based on professional sports leagues are this by design, given that a huge chunk of the appeal is to lead real teams to victory against their rivals. Each year, when a new version of the game is released, one of the most important features is that the roster is updated to reflect the real players on the current teams. Needless to say, such games have a very short shelf life, often falling into the bargain bin the moment the latest edition hits shelves.
  • 3D graphics tend to age very poorly. What looks innovative and realistic at first often falls straight into the Uncanny Valley after a few years as graphics capabilities improve.
  • The Edutainment Game genre is full of games that have aged poorly due to facts being debunked, new facts being discovered, or history changing. Unless it's something that changes very slowly like math or grammar it's unlikely a game will be accurate within fifteen years.

    Web Animation 

    Web Comics 
  • Gaming comics are like this almost by design, as they often reference then-current games.

    Web Original 
  • Pretty much any YouTube video that pokes fun at, really, anything about the site itself, as it changes constantly and extensively. References to one-to-five-star ratings make no sense after the site switched to a simple like/dislike rating system. Any video asking you to subscribe and pointing out where the subscribe button is will invariably point in the wrong direction because, as soon as video creators start getting clever about that (or start thinking little enough of their viewers that they find it necessary, depending on your interpretation), it moves to a completely different spot. And so on.
  • Todd in the Shadows, in his One-Hit Wonderland review of "Ridin'" by Chamillionaire, cited this trope as the reason why he doesn't cover more recent one-hit wonders for the show, as there's always a chance, no matter how seemingly remote, that they can make a comeback and render the episode obsolete now that they have more than one hit under their belt. He used Mike Posner as Exhibit A for this, noting that, before 2016, it seemed like he would forever be remembered for his lone 2010 hit "Cooler Than Me" and that he was the absolute last person who'd ever make such a comeback, only for him to drop a smash hit out of nowhere with "I Took a Pill in Ibiza" (a song that's all about being a washed-up one-hit wonder, at that).

    Western Animation 
  • The Simpsons:
    • The '90s:
      • In "Stark Raving Dad" (1991), all of Springfield becomes obsessed with Michael Jackson, dating it to pre-summer 1993 and MJ's drop in popularity domestically after he chose to settle instead of fight a child molestation suit.
      • In "Mr. Lisa Goes to Washington" (1991), the family meets Barbara Bush, and President George H.W. Bush appears at the end).
      • Capital City in "Dancin' Homer" is a parody of America's big cities at the time (1990), being portrayed as dirty, dark and dangerous (at least at night). This is hardly the case anymore as New York and Boston have "gentrified", though Detroit and Pittsburgh are still on dire straits.
      • "Sideshow Bob Roberts" lampoons the popularity of conservative talk radio in the mid-90s. Conservatism's battles with the cultural liberalism of the time led to it slipping out of the mainstream for almost two decades.
      • The episode "Homerpalooza" focuses on the pop culture at the time, more precisely the early years of Lollapalooza. The hip kids Lisa makes friends with in "Summer of 4 Ft.2" likewise embody the "indie" atmosphere of the time.
      • In "Lard of the Dance", Lisa's new classmate has a cellphone. It was supposed to serve as an indicator of how mature and grown-up she is, or at least is attempting to act. Today, with cell phones being far more common (to the point that some kids her age may actually have one, whether or not it was at their parents' insistence), viewers these days are probably more likely to complain about how bulky and primitive 1990s cellphones looked instead of the idea of a ten-year-old actually having a cellphone in the first place.
      • "Itchy & Scratchy Land" (1994) has a joke where Marge notes the bartender at a '70s-style disco bar looks like John Travolta, and the bartender looks from side to side before responding "Yeah, looks like..", very neatly dating it to pre-1994 and Travolta's Career Resurrection with Pulp Fictionnote . It also at one point shows a cutaway to a completely empty Euro-Itchy & Scratchy Land, a reference to the very difficult time Euro-Disneynote  had establishing itself in France, a situation that is today somewhat rectified (it finally turned a profit in 1995 and is now one of France's most popular tourist attractions).
      • "Beyond Blunderdome" (1999): The episode is a Mel Gibson vehicle. Gibson complains that people love him too much and that violence is dead in cinema. He ruins his career by filming a hyper-violent adaptation of a classic story beloved by many. Millennials reading: this is not an ironic statement. Also, while in Hollywood, Marge sees Robert Downey, Jr. in a shootout with police and Bart replies that there are no cameras. This was a joke. Back in the day.
      • Bart in I Married Marge (1991) suggests to name the new baby Kool Moe Dee, who was a well known rapper in the early 1990s but is now virtually forgotten. Lisa also suggests the name Ariel, the then most current Disney Princess.
      • "The Itchy and Scratchy and Poochie Show" (1997) is a perfect encapsulation of the nineties' obsession with Totally Radical characters with attitude and the desperate (and usually failed) attempt by corporations to appeal to kids of the time with forced hipness.
      • Frequent appearances of George H.W. Bush and later Bill Clinton, described as "the President".
      • While the overall plot of "Two Bad Neighbors" note  isn't really this, the ending where Homer becomes friends with Gerald Ford became this when Ford died in 2006.
      • In "You Only Move Twice" (1996), one way that Cypress Creek Elementary School is shown to be incredibly advanced is that they have their own website. On the DVD commentary, the writers admit that this is one of the show's most-dated jokes, as anything and everything (legal or otherwise) has a website (or, at the very least, an account with a social media site, like Twitter or Facebook), and the novelty of advancement has worn off significantly.
    • Turn of the Millennium:
  • South Park does this to a lesser extent beginning in Season 3, due to the short animation turnaround and their tendency to often use plots Ripped from the Headlines. Who even remembers spiderholes still?
  • Family Guy is bound to become very outdated in the future, due to numerous shout-outs and references to pop culture that even to younger generations today can be quite obscure and incomprehensible, like TV commercials and cartoon shows no longer on the air.
  • Any Band Toon is linked to the period it was made in by default, since they are usually made at the height a band's fifteen minutes of fame. As for Band Toons featuring fictional bands such as Alvin and the Chipmunks, it is the genre of their music that dates them (or the songs they do covers of).
  • Beavis And Butthead, in its original incarnation, epitomized The '90s (back when music videos still aired on MTV). With its triumphant return in 2011, and the focus on some of the shows MTV is now airing (including Jersey Shore and True Life) in addition to music videos, it looks like it's going to try to capture the zeitgeist of The New Tens as well.
  • Arthur has this tendency as well, but it's not as obvious as some other shows. Technology of the era are shown. One episode has him watching an Expy of "The Magician's Secrets Revealed" or refer to Harry Potter releases. Since they use expies, they're not as blatant.
  • Edutainment Show's are prone to this due to Science Marches On and History Marches On.

  • The failure of MySpace was largely because the website didn't innovate in time. The design during its zenith (2005-2008) was largely what one could expect of most websites in the early 2000s. The problem was that the internet moved on from that. The bulky, cumbersome, and unintuitive design of flash over substance that MySpace reeked of was quickly supplanted by sites like Facebook, which went for quick, efficient access, and sleek design. MySpace often had an air of a very high-end GeoCities type of website. And that was further hurt by profile customization: Anyone with the power to create a MySpace profile had the power to show everyone just how terrible they were at web design. In the age of easy access with simplified layouts (which is especially a MUST for the mobile aspect of the internet, which was another failure on MySpace's behalf), MySpace clung to a bulky, unintuitive interface (that was still very buggy to boot) for too long. And once it stagnated as the once popular party that most people abandoned, it especially couldn't shake the stigma of being "so 2005".
  • Smartphones and mobile devices generally. It's forgotten how recently these were introduced from the time of writing (July 2014) and how much they have changed the way people behave. iPhones came out in 2007, iPads in 2010.
  • MAD does this so well that compilation books from each decade since it began in The Fifties have been made. What seemed popular enough to be spoofed on their cover at one time might even two or three years later be forgotten. Sometimes due to a delay in publishing what it parodies may already be old news by the time the issue comes out.
  • Any map, due to changing political borders, countries or cities changing their names, things like The Great Politics Mess-Up, etc.
    • Even just a road map of an individual city or state can become a period piece due to new roads being built, existing roads being realigned, highway numbers being decommissioned or moved to different routings, etc. This is especially noticeable in the 1960s and 1970s while the construction of new Interstates was at its peak — they were often built in segments, and many had significant gaps in their routing. (For instance, Interstate 75 in Michigan was first designated in 1958 over a freeway south of Detroit that previously bore another designation, but it had a gap in mid-Michigan that was not filled until 1973.)
  • Highway design as a whole. Freeways themselves were generally more linear. Over time, on- and off-ramps, as well as transition roads between freeways, generally became larger and more sweeping, and the main routings of the freeways became more curved — most often done to lessen the displacement of neighborhoods or landmarks. Also, ramps used to be designed much smaller and tighter, due to a combination of space limitations, lower speeds on the freeways proper (many exits were designed in an era when 55 was the fastest speed limit), and less concern for things such as traffic patterns. (Few early exits provided complete access in every direction, had little acceleration/deceleration room [to the point that some ramps had yield or stop signs where they met the freeway, making it more like a hard right turn than a merge], or had entering/exiting traffic crossing over very closely.) Notably, entrance and exit ramps from the left sides of freeways were used in the past, but are being replaced wherever space allows due to the dangerous mix of speedy "fast-lane" traffic and slower merging traffic. (Some exceptions include I-290 west of downtown Chicago, and I-244 in Tulsa.) Even the once-common "cloverleaf" exit is being phased out, due to a major design flaw where merging and exiting traffic are forced to cross over each other's paths at the center (made even worse by the fact that the inner ramps that cross over are often signed at 25 MPH or slower). It's often easy to gauge the approximate age of a freeway, particularly if it has not been extensively rebuilt. (Particularly in California, where many of the older freeways still feature ridiculously sharp exit ramps.)
    • The Arroyo Seco Parkway between Los Angeles and Pasadena is now an intentional Period Piece; as the first freeway in the region, it's a designated historic landmark and will likely never be updated.
  • Certain neighborhoods, often in smaller towns, tend to come off like for reasons similar to the above two examples. Architecture may remain from certain decades without being rebuilt, as with designs of certain houses, style of sidewalk (or the lack thereof), or something as seemingly trivial as the width of roads. With today's wider cars, it's not hard to guess which street was built when.
  • According to Orson Scott Card, all fiction is this way to one degree or another, bearing identifying characteristics of its writer(s)'s time and culture.
    • Backstory time: This assertion was made by Card in reference to The Book of Mormon, which Card declared could not have been a hoax written by Joseph Smith because the way it is written differs too greatly from contemporary writers of Smith's time. Those whose sympathies are not resolutely with the Church of Latter Day Saints may want to take this theory with a grain of salt.
      • That said, the changes in language over time and this trope are often quite usable to determine when a work was written—sometimes even to identify something as a forgery, as it simply isn't using the language and conventions of the period it allegedly was written in. Basically, while that specific claim is dubious because he's not qualified to make it, the general claim isn't.
  • Any Stand-Up Comedy special or album will have the comedian commenting on life and culture at the time the special was originally made.
  • While any extraterrestrial life that may find it certainly won't care, the images encoded on the Voyager Golden Record attached to both Voyager Space Probes certainly portrays the world in in 1970's.
    • Depiction of real-world space technology in media can cause this for those familiar with it — works where Mars rovers all look like Sojourner looked strange after Spirit and Opportunity landed and even more so after Curiosity. The space shuttle's 30 years of service are a bit of an exception. (Of course, other things like the hair of the people seen onboard said shuttle can make it pretty easy to tell the 1980s from the 2010s...)
  • Ever since the 9/11 attacks on the original World Trade Center, pretty much any work set in New York City created prior to September 2001 is going to date itself by depicting the Twin Towers in any way.
    • Subsequently, numerous films and TV shows set in New York City between 2002 and 2009 will not feature any or all of the current (rebuilt) World Trade Center which has since completed construction.
  • This (SFW) Brazilian ad for Playboy contrasts 1975 and 2006.
  • Anti-drug crusades are dated to particular eras due to the drugs Moral Guardians are worried about. In the '60s and '70s, it was marijuana and LSD. In the '80s, it was crack cocaine. In the '00s, it was methamphetamine. In The New Tens, the main worry is opiods (prescription painkillers and heroin), as well as research chemicals (particularly synthetic cannabinoids).
  • Most political jokes really date the work they are in. After a few years out of office, any jokes about President or Prime Minister (insert name here) aren't going to be relevant and have the added downside of showing what political biases the author had.
  • This very wiki. Given its reliance on informal writing style and pop culture references, it can be very apparent when a certain entry or article was made (even when there are efforts to minimize such datings). For example, something written in the mid-to-late 2000's containing plenty of references to Haruhi Suzumiya or Tengen Toppa Gurren Lagann, while something from 2010 on will instead repeatedly refer to Puella Magi Madoka Magica or My Little Pony: Friendship Is Magic. In a few years, even those entries will inevitably seem dated.
    • Other entries or even pages can be dated with changes in naming conventions (No New Stock Phrases, tropes named after a character, etc.). While most have been renamed, the rename history and redirects still show the tendencies of the time.
    • The page for Present Day Past has a description that treats 2004 as recent enough for the trope to take effect, suggesting that people may accidentally leave their 2010 cultural artifacts in a story set back then.
  • You can tell the decade by those recyclable jokes about famine-struck areas. The same joke would be told in the 1960's about Biafrans, in the 1970's about Cambodians, in the 1980's about Ethiopians, in the 1990's about Serbians, and in the 2000's about Darfurians - the words would be absolutely identical, only the location and nationality changed.
  • If a work deals with LGBT characters in any way, it can pretty quickly date itself if it uses the word "transsexual". Though that used to be a perfectly acceptable term for people experiencing gender dysphoria, "transgender" became the preferred term around The New Tens, thanks to changing ideas about the dissonance between sex and gender.
  • Gay marriage being a) an issue at all (well into the 20th century few people - not even LGBT advocates - thought of such a thing) b) not possible in the place the work is set in. All US states and most of Europe have now legalized gay marriage or civil unions that are marriage in all but name. Few countries have legalized gay sex and an attitude towards homosexuality open enough to make a work with openly gay characters yet have no gay marriage, so a plot dealing with the inability of a gay couple to get married or the political struggle behind it inevitably dates itself to a time period between - at the earliest - the 1970s and at the latest 2015. There are of course many countries still without gay marriage, but most of them have homophobia enshrined in society or even law to such a degree that that would be Played for Drama and not the ability to get married.
  • Fanvids are usually quite easy to date, especially anime/manga ones or video game ones. Contemporary songs and series are commonly used for periods of them before being replaced. It's also noticeable due to what episodes/chapters someone uses in their amvs, and to a lesser extent what techniques are used for the videos,
  • One might look at the bonus material included in the Platinum or Diamond Edition DVD's or Blu-Ray's of vintage films remastered and re-released out of the Disney Vault and find special "behind-the-scenes" features on the making of the films, and/ormusic videos of pop-styled covers of the musical numbers contained in the film. Very often, the young celebrities featured in the BTS features and/or music video are stars of whatever in-vogue Disney Channel series or Disney Channel Original Movie that might have been in production at the time the Blu-Ray/DVD was released. Promos or trailers of then-upcoming PIXAR productions may be added as well.
  • Most low-budget movie logos from the 1960's - 1980's use very cheap animation set to synthesizer sound and sometimes, if they were expensive enough, to small orchestras. While in their time most people saw them as futuristic, you would nowadays see a lot of people that find them legitimately scary, as NightmareFuel.Vanity Plate demonstrates.
  • Any work that references the copyright status of a certain birthday song since the Supreme Court declared the song to be in the public domain in 2015.
  • Any work that references five and dime stores will date itself to the early to mid-20th century. Said stores fell out of favor by The '70s with inflation not helping matters.
  • Any work revolving around the Mayan Doomsday is instantly dated to before December 21st, 2012.
  • Any work that references "Don't ask, don't tell" is instantly dated between 1994 at the earliest when the policy was first instituted to 2010 at the latest when the policy was repealed.
  • Any work that references or features video rental stores date themselves to the 1980s at the earliest to the Mid-2000s at the latest as the rise of online streaming services in the late-2000s and early-2010s caused many of these stores to go out of business.
