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 a show involving two men sitting at a bar in some tropical country. One in a military-looking uniform with a hammer-and-sickle badge on the side is whispering in heavily accented English about his worries that the Berlin Wall may not last. The other man, sporting a glorious mullet, clips his absolutely gigantic cell phone to his belt before putting his hand on the other man's shoulder reassuringly.

When viewed by someone with even a shaky grasp of history, the historical period is blindingly obvious. Such a scene would have been made at the time with the focus entirely on Cold War politics, but the first thing the modern audience notices are the clunky cell phone and the mullet.

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it becomes more than a decade old due to the characters referencing old trends, wearing out of style fashions and using out of date technology, this trope only really applies to works that wear their dates so blatantly that a viewer can identify the era or even year it was made in as soon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, and We're Still Relevant, Dammit, for when long-running series make blatant (and sometimes forced) references to modern culture in an attempt to seem up-to-date or to look more "hip", often resulting in one of these. 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 '90s 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. If, somehow, the work manages to feel just as relevant today as it did than, if not more so, it's an example of Values Resonance, not this trope. 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. In more than a few episodes, the children wonder where their next meal is coming from.
  • 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.
  • Angels with Dirty Faces, due in part to its "Mister Sandman" Sequence.
  • 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 
  • Anchors Aweigh
  • 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.
  • Guys and Dolls.
  • 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 
  • Leave It to Beaver.
  • I Love Lucy
  • The Honeymooners, though the show was always slightly more realistic than other sitcoms around at the time.
  • Father Knows Best.
  • 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 original Washington Senators, which moved after 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 
  • Barbarella is the '60s.
  • 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.
  • Midnight Cowboy
  • Revolution (1968) captures the feeling of the 1960s, even though the topics in the documentary might seem old-fashioned nowadays.
  • One, Two, Three 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.
  • Rowan and Martin's Laugh-In.
  • 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 Monkees.
  • 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.
  • Walt Disney attempted to avert this with The Jungle Book, specifically the vultures. Hence, the vultures talk like The Beatles but don't sing like them, as Walt felt that a bunch of Beatles expies would date the film. Instead they sing like a barbershop quartet. Suffice it to say that a Beatles-style number would have aged far better, but considering that barbershop dates back to the early 1880s while the Beatles were still a fairly new fad, how was Walt to know that?


    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.
  • 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").
  • 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.

    2010s Literature 
  • Kire tries it's best to be cool and hip, to the point of almost misogonic to not fall under Girl Show Ghetto from being written by a woman. The main character has a Darth Vader(Even though not unusual does it give him a 90s kids vibe) alarm clock and quite a bit of "Justin Bieber is just so lame!" comments.
  • 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 South Carolina, 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.
  • It's inevitable that Empire—a show about the hip-hop industry and featuring the decade's music styles, fashion trends, and real-world controversies—will be laughably dated by the 2020's. Hakeem in particular is practically the poster boy for New Tens' music, clothing, and technology.

    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 (namely, "Bring 'Em Down" and "We Bring an Arsenal"), something that would be unthinkable just a few months later, where frontman Ian Watkins was arrested, charged, and sentenced to 35 years in prison for child molestation. On a lighter note, the DJ on the rock station makes a crack about the Mayan Doomsday when discussing Darius Flynt's success in the competition, firmly pegging the game to the early '10s when that was the subject of a great deal of media attention.
  • 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.
  • Marvel: Avengers Alliance will be very dated in the near future, due to Spec Ops that tied in to Marvel comics and movies of its time and were only available for a limited time. Never mind that it was only playable from March 1, 2012 to September 30, 2016.

    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. However, later episodes are starting to fall into this with growing references to mid-2010s pop culture and memes.
    • 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. Later on, the series made another jab at Trump's anti-Muslim rhetoric with "The Times They Are a Changeling" in which Spike befriends a creature of a feared race in Equestria.
    • The Season 6 finale in which Starlight Glimmer assembles an "unlikely team of heroes" is very much inspired by the mega blockbuster hit Suicide Squad (2016) and will premiere mere months after the release of said movie.
    • 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.
