->''"With dated [[TheSixties '60s]] references like these, we won't have much of a life in reruns!"''
-->-- '''[[HypocriticalHumor Babs Bunny]]''' imitating [[WesternAnimation/RockyAndBullwinkle Rocky Squirrel]], ''WesternAnimation/TinyToonAdventures''

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 [[PopularHistory 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 ''Series/BarneyMiller''. 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 there[[note]] The subject of the decision was police raids on gay bars, something whose legal ins and outs Captain Miller could reasonably be expected to know[[/note]]. 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.

NarrowParody 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it becomes more than a decade old due to the characters referencing old trends, wearing out of style fashions and using out of date technology, this trope only really applies to works that wear their dates so blatantly that a viewer can identify the era or even year it was made in as soon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 ''Series/{{Friends}}'' and ''Series/{{Frasier}}'' show their age in many respects, they don't wear TheNineties 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 - inverting DontExplainTheJoke 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 [[GeniusBonus read the joke and get a good laugh out of it still]] and these jokes can liven up an otherwise dullish history lesson, or a [[SmallReferencePools group of people knowledgeable of the era]], or catch your grandparent off guard "I haven't heard that joke for years!".

Subtropes include FashionDissonance (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|MarchesOn}} and [[SocietyMarchesOn Society Marching On]], AluminumChristmasTrees, and scenes that would resemble {{Mister Sandman Sequence}}s if they occurred in an ''actual'' period piece. Compare with TwoDecadesBehind, 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 ThisVeryWiki, [[DiscreditedTrope the very tropes in use]] may be recognisably of an era -- such as the NinetiesAntiHero.

Note that a work being a product of its time [[TropesAreNotBad doesn't necessarily mean it isn't relevant or entertaining to modern audiences]], even notwithstanding the kitsch or nostalgia factor ([[ValuesResonance as many of the examples below will demonstrate]]). If the work's severe datedness also makes it inaccessible to modern audiences, then you have ValuesDissonance. However, this trope can overlap with ValuesDissonance if an intellectual fashion was very short-lived. When a work's ''popularity'' can be specifically dated to a certain era, that makes it DeaderThanDisco. If a concept was new in its day but is now well-established and evolved beyond that, you're looking at SeinfeldIsUnfunny. Obviously films done in black and white, 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.

* Anything Creator/FScottFitzgerald ever wrote during the course of his career.
* For a specific example: In ''Literature/TheGreatGatsby'', Gatsby's life story- real or imagined- with references to World War 1 and bootlegging places the story firmly in the Prohibition era.
[[/folder]]

!! [[TheGreatDepression 1930s]]

[[folder:1930s Comics]]
* The first volumes of ''ComicBook/{{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 NoCelebritiesWereHarmed fashion). After WorldWarTwo many of these numbers were redrawn and rewritten.
[[/folder]]

[[folder:1930s Film]]
* ''Film/TheLittleRascals'', which today come off as quaint stories your grandparents might tell about being children at the time.
* Any given [[SilenceIsGolden 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.
** Ironically, in the 2011 film ''Film/TheArtist'', this could be an InvertedTrope, the film as a comment on the desperate employment and fiscal conditions many people faced during TheGreatDepression rings true to RealLife in the present time almost as ValuesResonance.
* ''Film/TheWizardOfOz'' averted this trope by cutting a [[CutSong musical number]] in which the Wicked Witch of the West sends "[[{{Jazz}} jitterbugs]]" to torment Dorothy and her friends, specifically to avoid dating the movie.
%%* ''Film/AngelsWithDirtyFaces'', due in part to its MisterSandmanSequence.
* ''Film/GoldDiggersOf1933'' evokes TheGreatDepression in both its story and its songs. [[JustifiedTrope 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 ''Film/ModernTimes'': 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 ''Film/AFreeSoul'', 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.[[/folder]]

[[folder:1930s Literature]]
* Most of the works of Creator/JohnSteinbeck. (Arguably a ''[[TropesAreNotBad good]]'' [[TropesAreNotBad thing]], since [[CrapsackWorld Steinbeck's protagonists don't tend to meet happy fates]].)
[[/folder]]

[[folder:1930s Theatre]]
* ''Theatre/TheWomen''. The author's 1960s SettingUpdate of her play has been generally ignored, and revivals tend to be based on GorgeousPeriodDress.
* A SettingUpdate of ''Theatre/OfTheeISing'' reached Broadway in 1952, and flopped. Later productions have reverted to the original 1931 version, in which [[TheGreatDepression "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 [[http://en.wikipedia.org/wiki/Hoover_Moratorium 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 UsefulNotes/NaziGermany 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.
* ''Theatre/MarginForError'', written in 1939, is tied to a rather specific point in the diplomatic history of UsefulNotes/NaziGermany. 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 UsefulNotes/WorldWarII, which forced the plot to be framed as a {{flashback}}.
[[/folder]]

[[folder:1930s WesternAnimation]]
* The cartoons of Creator/MaxAndDaveFleischer, especially when they'd have a MusicalEpisode featuring Music/CabCalloway or Music/LouisArmstrong. WesternAnimation/BettyBoop herself, a flapper, had already become dated by the end of the 1930s. ([[TheRoaringTwenties Twenties]] in this case).
* The WesternAnimation/PorkyPig 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.
* It's technically a film from the '40s (1941), but Disney's ''Disney/{{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 ''WesternAnimation/SouthPark'' episode that subtly parodied the phenomenon with a big fuss in the town over five identical Romanian girls.
[[/folder]]

!! [[WorldWarII 1940s]]

[[folder:1940s Film]]
%%* ''Film/AnchorsAweigh''
* ''Film/TheGreatDictator'' actually could be considered a couple of years ahead of its time, since back when America was neutral, the Nazis were rarely badmouthed in the media. But it is cemented as an early Forties film that could not have been made after UsefulNotes/WorldWarII because Creator/CharlieChaplin couldn't have known the full scale of the Holocaust at the time the film was made (the Nazis are shown bullying and harassing the Jews, but nothing much worse than that). Chaplin later said that if he'd known about the full scale of it at the time, he wouldn't have made the film.
* Likewise the award-winning ''Film/TheThreeStooges'' 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.
* "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 began to be viewed as possibly treasonous by 1942, when the US was at war with Nazi Germany
* ''Film/GentlemensAgreement'', a 1947 film about Anti-Semitism, references several 1940s politicians and scandals. At the time, its topicality made it AwardBait; today, these references would send a history professor running to TheOtherWiki.
* ''Film/KittyFoyle'' is soaked in 1940 sexism. 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 LoveTriangle that forms the plot, plays solitaire with her on their first "date" as a test to make sure she isn't a GoldDigger. When he sees Kitty's less attractive roommates, he says "I've seen better specimens in a glass jar."
[[/folder]]

[[folder:1940s Music]]
* "Route 66". The title route became a lot less relevant when the Interstate highway system was enacted in the 1950s, combined with the re-routing of US-66 to include freeway-grade bypasses of many major cities in the 50s and 60s. As Interstates became more prominent in the 60s and 70s, many of said bypasses, and even some portions of the "original" Route 66, were supplanted by the several freeways that ended up taking over US-66's original function over the next couple decades (mostly Interstates 40, 44, and 55). The number was finally decommissioned in 1985.
[[/folder]]

[[folder:1940s Theatre]]
* ''Theatre/OneTouchOfVenus'' has a few throwaway lines and walk-ons that betray the fact that it was written and produced during UsefulNotes/WorldWarII (which figures not at all into the plot).
[[/folder]]

[[folder:1940s WesternAnimation]]
* Any WartimeCartoon.
* ''WesternAnimation/LooneyTunes'' shorts tend to be full of the pop culture of the decade they were made, particularly those made in the 1930s and '40s. This could also be said of episodes of ''WesternAnimation/TomAndJerry'', ''WesternAnimation/WoodyWoodpecker'' or any number of cartoon shorts.
** Any short directed by Creator/TexAvery is especially full of dated and forgotten {{Memetic Mutation}}s of the day.
** The ''WesternAnimation/TomAndJerry'' short "The Zoot Cat" deserves special mention, not only for its 1940s FashionDissonance but because the slang and the dances featured in it place it firmly in the 1940s.
* The 1946 [[WesternAnimation/ClassicDisneyShorts Disney short]] "All the Cats Join In", with its jazz soundtrack produced by Music/BennyGoodman, features teens partying in a malt shop, doing swing dancing as a jukebox plays.
** Also the WesternAnimation/DonaldDuck cartoon "Wide Open Spaces" showed Donald refusing to pay the (at the time) expensive price of $16 to stay at a hotel. These days, it makes Donald look ''really'' cheap, which is actually almost funnier.
[[/folder]]

!! [[TheFifties 1950s]]

[[folder:1950s Film]]
* Hysterical RedScare films like ''I Married a Communist!'' date to a very specific point in time.
%%* ''Film/GuysAndDolls''.
* Downplayed but still present with TheMovie of ''Film/WestSideStory'', which was made (very early) in TheSixties 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.
* ''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.
* ''Film/TheSevenYearItch'' (1955) is a time capsule of the mid-1950s due to ValuesDissonance 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 CelebrityParadox: the characters going to a theater to see ''Film/CreatureFromTheBlackLagoon'', a pretty blatant parody of ''Film/FromHereToEternity'', etc. Perhaps most striking, however, is the characters' discussion of the [[Creator/MarilynMonroe 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.
* ''Film/AFaceInTheCrowd'' 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.
[[/folder]]

[[folder:1950s Literature]]
* A couple of Ian Fleming's ''Literature/JamesBond'' stories from ca. 1959 reference the anti-Batista forces in revolutionary Cuba with some sympathy, which wouldn't be the case a year or so later.
* Max Shulman's 1957 novel ''Rally Round the Flag, Boys!'' has suburban housewives organizing committees to welcome a [[http://en.wikipedia.org/wiki/Project_Nike Nike installation]], which leads to a fight between soldiers and GreaserDelinquents. Throwaway references include a HenpeckedHusband comparing trying to make a date with his wife with "like trying to get tickets to ''Theatre/MyFairLady''."
[[/folder]]

[[folder:1950s LiveActionTV]]
%%* ''Series/LeaveItToBeaver''.
%%* ''Series/ILoveLucy''
%%* ''Series/TheHoneymooners'', though the show was always slightly more realistic than other sitcoms around at the time.
%%* ''Series/FatherKnowsBest''.
* ''Series/TheTwilightZone''. 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 ColdWar and RedScare in many episodes. There is of course still some ValuesResonance to be found in some episodes though, so it varies from episode to episode.
* Creator/RogerEbert has written 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 - ''DavyCrockett'', ''Series/TheMickeyMouseClub'', ''Franchise/{{Zorro}}'' - not just to the mid-1950s, but to the exact year and sometimes to the exact month.
[[/folder]]

[[folder: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 Music/ChuckBerry 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....
** Later covers of the song avert this; you can change it to 1996 or 2006 and the song's no longer dated.
[[/folder]]

[[folder:1950s Theatre]]
* ''Theatre/BellsAreRinging'' 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 ListSong rattling off the names of 1950s celebrities (which, like a number of similar songs from Music/ColePorter musicals, had a few lines revised during the original Broadway run).
* ''Theatre/DamnYankees''. Most obviously, the protagonist roots for and then plays for the Washington Senators, which moved in 1960 to become the Minnesota Twins.
* ''Theatre/LilAbner'' 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.
* ''Theatre/TheMostHappyFella'', 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.

!! [[TheSixties 1960s]]

[[folder:1960s Film]]
%%* ''Film/{{Barbarella}}'': This film ''[[IAmTheTrope is]]'' [[IAmTheTrope 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.
* ''Film/MagicalMysteryTour'', 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.
%%* ''Film/MidnightCowboy''
* ''Film/{{Revolution 1968}}'': This {{Documentary}} captures the feeling of the 1960s, even though the topics in them might seem old-fashioned nowadays.
* ''Film/OneTwoThree'': This film ''literally'' became a period piece ''during'' shooting -- when the production started, the BerlinWall 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 JamesCagney's character and his companions and some East German policemen that continued over the border between East and West Berlin, EastGermany very unobligingly decided to put up the Wall. The film is written and performed as if still in the pre-wall period.
[[/folder]]

[[folder: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 forward to ''Literature/TheWarriors'', Sol Yurick notes that at the time the book was written, gangs had limited access to guns and cars.
[[/folder]]

[[folder:1960s LiveActionTV]]
* ''Series/TheBradyBunch'' bleeds its late 1960s/early 1970s origin, due to FashionDissonance 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.''
%%* ''Series/RowanAndMartinsLaughIn''.
* The ''Series/{{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 Warhol and Liechtenstein, 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.
%%* ''TheMonkees''.
* ''WesternAnimation/TheBananaSplits'', 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.
* ''Series/MissionImpossible'' 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, ''Series/StarTrekTheOriginalSeries'' has this going on alongside its {{Zeerust}}. Between the color palette, the miniskirts, the ColdWar 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.
* ''Series/ThePrisoner'', 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 Music/TheBeatles ("All You Need Is Love") and a character, thematically representing universal youth culture, calling everyone "dad" or "baby".
[[/folder]]

[[folder:1960s Music]]
* "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 Music/TheWho manages to still sound reasonably timeless until it betrays the fact that it was written before British currency was decimalised with "[[UsefulNotes/OldBritishMoney Thruppence and sixpence]] every day just to drive to my baby".
* Music/ElvisPresley 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.
* Music/TheBeatles' "Taxman" 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.
** "[[Music/SgtPeppersLonelyHeartsClubBand 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 TheSixties.)
** The song "Revolution" has the line "If you go carrying pictures of chairman [[UsefulNotes/MaoZedong 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.
* A lot of Music/FrankZappa's work are period pieces, most blatantly with ''Music/WereOnlyInItForTheMoney'', which satirizes the hippie movement.
* Scott [=McKenzie=]'s OneHitWonder "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 [[http://en.wikipedia.org/wiki/Summer_of_Love "Summer of Love"]].
* ''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 Music/TheBeatles' 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. Music/TheRollingStones' ''Music/TheirSatanicMajestiesRequest'' and Music/TheMoodyBlues' ''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 [[CaptainErsatz Pepper imitations]] which now sound like standard products of their own decade include Music/TheSmallFaces' ''Ogden's Gone Nut Flake'' and Music/PinkFloyd's ''Music/ThePiperAtTheGatesOfDawn''
* "Kay" by John Wesley Ryles, a 1968 country music song about a broken-hearted taxicab driver. Two of his customers are soldiers who say that they hate "that war in Vietnam".
[[/folder]]

[[folder:1960s Theatre]]
* ''Theatre/{{Hair}}'' focused heavily on TheSixties while they were still going on, but did so intentionally.
* ''Theatre/TheBoysInTheBand'' is ''very'' much a look at the [[{{Gayngst}} 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]]In real life, it didn't reach 1,000 for the first time until late 1972. The Dow was last under 1,000 back in 1982.[[/note]]
** Many jokes rely on the audience being familiar with Lane Bryant (a women's clothing store popular at that time) and ''Film/TheGraduate''.
** 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.
[[/folder]]

[[folder:1960s WesternAnimation]]
* ''Franchise/ScoobyDoo'', 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, ''WesternAnimation/RockyAndBullwinkle''. 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 (''WesternAnimation/TinyToonAdventures'' 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]]Owned by a joint partnership of [[Creator/DreamWorksAnimation DreamWorks Classics]] and the Jay Ward estate, syndication rights are owned by General Mills via The Program Exchange[[/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.
* ''WesternAnimation/TheFlintstones'' and ''WesternAnimation/TheJetsons'', despite taking place in the past and the future respectively, have enough 1960s pop culture references that they come off as "The 1960s [[RecycledInSpace With Cavemen]]" or "The 1960s [[RecycledInSpace With Flying Cars]]".
** The 1980s ''Jetsons'' revival is a weird double example, essentially being 1980s pop culture references in a [[ZeerustCanon 1960s-style future]].

[[folder:2010s Film]]
* One of [[http://io9.com/5719453/gullivers-travels-will-make-you-seasick-in-the-cineplex io9's chief criticisms]] of the 2010 movie adaptation of ''[[Film/GulliversTravels2010 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 ''[[http://www.imdb.com/title/tt1592531/ The Holy Roller]]'' has [[HarsherInHindsight sadly become this]], thanks to the Canterbury earthquakes of 2010 and 2011.
* The 2012 film version of ''Film/TheThreeStooges'' attempts to be an updating of the famous comedy team, yet also dates itself severely by including the cast of JerseyShore as themselves for much of the film.
* The EddieMurphy comedy film ''A Thousand Words'' was made in 2008 but released in 2012. It featured Flip Phone product placement, "The Shack" and Miley Cyrus were referred to as hot trends, and the protagonist was a wealthy literary agent who would not exist in an e-book era. Many critics used the phrase "Unintentional Period Piece" in their reviews.
* If the film is ever released, David O. Russell's BlackComedy ''Nailed'' would be one of these. 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 society marching on due to the Affordable Care Act, this premise is now considered dated and would severely limit its audience due to the irrelevance (another factor is that Russell refuses to finish the film due to fights with the film's producer).
* ''Vampires Suck'', as mentioned above, and ''Film/TheStarvingGames'' (the [[Music/{{PSY}} Gangnam Style]] "joke" ALONE arguably throws it into this category).
* ''WesternAnimation/TheNutJob'' 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).
* ''Film/TwentyOneJumpStreet'' relies on things that have changed among teenagers between the mid-2000s and early 2010s for much of its humor.
[[/folder]]

[[folder:2010s Live Action TV]]
* A funny one occurred on ''Series/NCISLosAngeles'' when the subject of one episode was Libyan government agents sent by Qaddaffi 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 2011) the rebels would be more properly called "The Libyan Government", having been recognized as such internationally in September 2011 with Qaddaffi the one on the run who should be wary of ambushes. The "Arab Spring" references also clearly date the show.
* ''Series/BreakingBad'' 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. However, the use of flip-phones by every character rather than smartphones baffles some viewers. On the other hand, smartphones do start to proliferate toward the end of the series.
** This is a case of ShownTheirWork for the main characters, as cheap, pre-paid cell phones are very commonly used by drug dealers because their low cost and lack of binding contracts makes them easy to dispose of and quickly replace as needed.
* Turn on almost any given episode of ''{{Series/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 ''KidsIncorporated'' in the 1980s and early '90s). Since the musical is essentially an old-fashioned genre, these shows often try to [[WereStillRelevantDammit 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.
* ''Series/HowIMetYourMother'' is starting to become this with frequent pop culture references to things like ''Film/{{Inception}}'', [[MemeticMutation memes]], and ''Literature/FiftyShadesOfGrey''. Possibly justified, as the {{Framing Device}} dates the show by the month/year. The references would be hip at the time of the episode.
* In ''Series/TheFosters''' fifth episode, the morning-after pill is kept behind the counter, available to over-16s only; the tenth features a fully legally sanctioned California same-sex wedding, placing them before and after the 2012-13 Supreme Court session, respectively.
[[/folder]]

[[folder:2010s Music]]
* The Music/RiseAgainst song "Make It Stop (September's Children)", which is about homophobic bullying and makes reference to a number of high-profile gay teen suicides.
* The Chainsmokers' song "#SELFIE" is definitely ingrained with the early 2010s, mentioning taking selfies with Instagram, [[Music/LanaDelRey "Summertime Sadness"]], and calling another girl "ratchet".
[[/folder]]

[[folder:2010s Web Original]]
* This trope is lampshaded by Matt and Pat of ''WebVideo/TwoBestFriendsPlay'' during their playthrough of ''VideoGame/ResidentEvil4''. Early on Matt talks about how early previews of ''VideoGame/TheEvilWithin'' 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 Wrestling/VinceMcMahon 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).

[[folder: 2010s Western Animation]]
* A few episodes of ''WesternAnimation/{{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 BarackObama 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 DVDCommentary.
* The ''WesternAnimation/SouthPark'' 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.

!!Special Cases (either multiple decades, or OlderThanRadio)

[[folder:Advertising]]
* 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 CharlieBrooker [[http://www.youtube.com/watch?v=WVj389dsd6o&feature=g-vrec explains]]:
-->"Old adverts are like little nostalgia bombs, really. Each one sums up the year in which it appeared in an instant. [[TheSixties '60s]] ads are cool and swinging, the [[TheSeventies '70s]] ads are sort of [[RealIsBrown brown and grotty]], whereas [[TheEighties the '80s]] were characterized by {{power ballad}}s and absolute swaggering fuckery like this." ... "[[TheNineties '90s]] ads were all huggy-wuggy and sophisticated, whereas [[TurnOfTheMillennium the noughties]] can't decide if they're all troubled and [[DadaAd 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 MisterSandmanSequence complete with [[Series/AdventureTime Finn and Jake]] and [[http://www.autoevolution.com/news-image/honda-promotes-2014-civic-coupe-with-love-today-ads-video-74379-1.html pictures of animals from memes]].
[[/folder]]

[[folder:Comic Books]]
* Look at any issue of ArchieComics. 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 "LoveTriangle"-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.
* ''[[ComicBook/TwoThousandAD 2000AD]]'' has an interesting relationship with this trope, being something of a LongRunner:
** [[TheSeventies Early]] ''Comicbook/JudgeDredd'' stories were often steeped in the ColdWar, 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 ''[[{{Savage}} Invasion!]]'' and especially ''ABCWarriors'' was an incredibly obvious Soviet stand-in, at least until they were retconned.
** During TheEighties, nearly every strip made some reference to MargaretThatcher or RonaldReagan.
** TheNineties featured strips such as the [[Music/SpiceGirls ''Space Girls'']] and [[TonyBlair ''BLAIR 1'']] (a parody of ''MACH 1'', an early strip from 1977) in order to stay relevant. These were not well-recieved.
* Many superheroes have dated origins, according to either comics canon or tradition. Bruce Wayne became Franchise/{{Batman}} after seeing his parents get shot outside a movie theater showing ''The Mark of Zorro'' (1940), while Bruce Banner became TheIncredibleHulk 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 [[{{Retcon}} altered by later stories]].
* Many of the early {{Avengers}} comics ended up becoming incredibly dated, not just due to the DirtyCommunist type villains common in that era, but also because of many pop culture references included in the stories.
[[/folder]]

[[folder:Film]]
* Porn films. Due to NoPlotNoProblem, most porn is set in the time it was filmed in, the performers wearing their streetclothes and current haircut. When released it looks "normal", but give it 10-20 years and it's a period piece. The video quality and [[BowChickaWowWow soundtrack]] can make it look even more dated.
* {{Exploitation film}}s have a strong tendency to fall into this, due to the way exploitation filmmaking works.
* ''Film/TheThreeStooges'' shorts, made from [[UsefulNotes/TheGoldenAgeOfHollywood the 1930s through the 1950s]], were always a product of their time.
* [[SilenceIsGolden Silent films]], except for the handful made in the 1930s by Creator/CharlieChaplin, will always be associated with [[SilentAgeOfHollywood the 1910s and 1920s]].
* Most of the ''Film/JamesBond'' films, with each version of Bond being this to (roughly) one particular decade. The Creator/SeanConnery films have their feet planted in TheSixties, Creator/RogerMoore's Bond is a product of TheSeventies, the Creator/TimothyDalton films are products of TheEighties, the Creator/PierceBrosnan films are filled with the [[TheGreatPoliticsMessUp post-Cold War]] vibe of TheNineties, and Creator/DanielCraig's DarkerAndEdgier Bond is a man of the TurnOfTheMillennium and TheWarOnTerror.
* ''Film/WestSideStory'' 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.
[[/folder]]

[[folder:Jokes]]
* This joke is funny, but the boy in the joke has to be from the 1970's-1990's to have a grandfather who in WorldWarII, 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."

[[folder:Literature]]
* Creator/JaneAusten's books, which define the Regency Romance subgenre.
** ''Literature/PrideAndPrejudice'' is used on the PeriodPiece page to illustrate a story whose crisis DoesNotCompute in a present-day 21st century setting.
** ''Literature/NorthangerAbbey'' 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 GothicHorror 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.
* Creator/StephenKing's works are [[ReferenceOverdosed chock full of pop-cultural references]] from whenever the book was written, to an almost ''WesternAnimation/FamilyGuy''-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.
* The ''Literature/SherlockHolmes'' stories, which practically ''define'' VictorianLondon to modern audiences. Part of Creator/StevenMoffat's motive in writing ''Series/{{Sherlock}}'' was that he felt the books' nature as Unintended Period Pieces was getting in the way of what Creator/ArthurConanDoyle ''intended'' them to be, which was crime thrillers.
** Well... it is a bit more complicated than that. Doyle kept writing Sherlock Holmes stories until 1927 but he never ''set'' any of them later than 1914 - and even that story ('The Last Bow') is far later than the others. Most Holmes stories written in the 1920s were set two decades (or more!) in the then past making them ''intentional'' period pieces.
* Vintage movie reviews often fall prey to this, usually because of a critic either [[ItWillNeverCatchOn panning a movie that goes on to become a cult classic]] or [[ThisIsGoingToBeHuge lavishly praising a movie that nobody likes years later]]. Most film critics are well aware of this fallacy and have learned to laugh at themselves because of it, but there are critics who take the tendency UpToEleven. Creator/RogerEbert, for example, has been known to pepper his reviews with TotallyRadical slang (perhaps to [[WereStillRelevantDammit stay relevant, dammit]]), mentioning "dig" (as in, "think something is cool") in his 1972 review of ''TheGodfather'' and "the max" (meaning "the greatest") in his 1985 review of ''WeirdScience''. [[https://twitter.com/ebertchicago/status/8092631309 Sometimes in parody]].
* Dan Simmons' ''Literature/HyperionCantos'' 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 ''Literature/JamesBond'' novels fall into this when it comes to fashions and [[ValuesDissonance 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 ColdWar culture in which he was writing.
* Creator/PGWodehouse's books took place in a kind of flexible ComicBookTime version of the GenteelInterbellumSetting 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 Literature/NancyDrew and Literature/TheHardyBoys 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 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 ''Series/GeneralHospital'' 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 Creator/BillBryson's travelogues; In ''The Lost Continent'' Bryson is startled to see how much America had changed since TheSixties. 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 [[TheYugoslavWars pre-Balkan war Yugoslavia]], pre-[[https://en.wikipedia.org/wiki/%C3%98resund_Bridge 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.
[[/folder]]

[[folder:Live Action TV]]
* Quite unavoidable with a LongRunner such as ''Series/DoctorWho'' -- 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 "[[Recap/DoctorWho2007CiNSTimeCrash Time Crash]]", which alternates between the grand orchestral score of the Tenth Doctor's era and the the [[{{Retraux}} 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 [[ImpossiblyTackyClothes incredibly awful even in-universe]], it's really only a mild exaggeration of [[IWasQuiteAFashionVictim hideous things people sincerely wore in the 80s]].
** Played with in the novelization of "[[Recap/DoctorWhoS17E6Shada Shada]]", which was a 1979 DevelopmentHell episode originally written by Creator/DouglasAdams, and eventually novelized by a writer on David Tennant/Matt Smith-era ''Doctor Who'' in 2012. As a result, the 1970s setting, which was LikeRealityUnlessNoted 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 Music/StatusQuo 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.
** In the episode "Rose", we know it was made in the early-to-mid 2000s because the Tylers still don't have internet access at home or even a computer, so Rose has to go over to her boyfriend's house just to look something up online.
* ''Series/SoulTrain'': Mainly for TheSeventies, but also for TheEighties and TheNineties.
* Thanks to the RippedFromTheHeadlines formula, ''LawAndOrder'', depending on the season, can seem quite dated. [[AvertedTrope On the other hand]], the fact that they just [[NoCelebritiesWereHarmed switch the names]] makes it so that the older episodes can still be enjoyed [[TropesAreNotBad on their own merit]].
* Episodes of ''Series/SaturdayNightLive'', thanks to its musical guests and its use of topical, current events humor (from [[http://en.wikipedia.org/wiki/General%C3%ADssimo_Francisco_Franco_is_still_dead "Generalíssimo Francisco Franco is still dead"]] to [[TinaFey "I can see]] [[SarahPalin Russia from]] [[MemeticMutation my house!"]]), can be dated almost to the year.[[note]]For those guessing, the Franco one is from 1975, ''SNL'''s first season.[[/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 GameShow 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 ''Series/WheelOfFortune'' was LIFE WITH BONNIE, a short-lived Creator/{{ABC}} sitcom that is barely a footnote in Bonnie Hunt's career.
** Commented on in ''Series/WhereInTheWorldIsCarmenSandiego''. 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 TheGreatPoliticsMessUp, TheYugoslavWars 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, ''Series/WhereInTimeIsCarmenSandiego'', 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.
* Happens a lot more in ''Series/StarTrek'' 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 [[TheEighties 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 TechnologyMarchesOn.
* Episodes of ''Series/ThePriceIsRight'' from the 20th century often included outdated technology such as [=VCR=]s 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).
* Long-running {{talk show}}s and {{panel show}}s in general, due to their reliance on topical guests and events for interviews, jokes, and musical performances.
* British panel show ''Series/NeverMindTheBuzzcocks'' 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 Wonder}}s. (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]]Not long afterwards, his reputation was destroyed by a pedophilia scandal[[/note]]
** A more recent example would be the times Simon Amstell [[HarsherInHindsight 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...
** ''Series/{{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 PsychedelicRock song in one ep of ReturnOfUltraman.
** The first five ''Franchise/KamenRider'' series (''Series/KamenRider'' through ''Series/KamenRiderStronger'') are essentially products of the 1970's, given the heroes' fashions.
*** ''Series/KamenRiderSuper1'' 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 ''Series/{{Chips}}''.
* The producers ''Series/FreaksAndGeeks'' 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 LiveAction/SaturdayNightLive, LiveAction/ChappellesShow, LiveAction/MadTV, and LiveAction/InLivingColor).
[[/folder]]

[[folder:Music]]
* 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 [[http://www.youtube.com/watch?v=i7iQbBbMAFE "Free Your Mind"]] and see whether it doesn't ''scream'' 1992 (A big hint is a [[FreezeFrameBonus "blink and you'll miss it"]] shot of one guy's shirt referencing the 1992 L.A. Riots).
** And a close second place behind goes to music videos filmed on location in urban landscapes - cars, architecture, fashions, advertising - you name it. Cases in point:
*** Any music video filmed during New York's [[TheBigRottenApple Big Rotten Apple]] phase, such as Music/GrandmasterFlashAndTheFuriousFive's "[[http://www.youtube.com/watch?v=O4o8TeqKhgY The Message]]".
*** The video for "[[http://www.nzonscreen.com/title/auckland-tonight-1981 Auckland Tonight]]" by UsefulNotes/NewZealand punk band The Androidss captured Auckland city nightlife as it appeared in 1981.
*** Music/PhilCollins travels round the world in the video for "[[https://www.youtube.com/watch?v=sRY1NG1P_kw Take Me Home]]". In particular, he's seen in UsefulNotes/{{London}}, UsefulNotes/{{Paris}}, UsefulNotes/NewYorkCity, UsefulNotes/{{Tokyo}}, [[UsefulNotes/{{Sweden}} Stockholm]], UsefulNotes/{{Moscow}}, UsefulNotes/{{Sydney}}, Memphis, UsefulNotes/LosAngeles, UsefulNotes/SanFrancisco, UsefulNotes/{{Chicago}}, [[EverythingIsBigInTexas Texas]], and [[UsefulNotes/StLouis St Louis]] -- as they all appeared in 1985.
* Many, but not all, [[ProtestSong political songs]] fall into this category. To name a few:
** Music/GilScottHeron's ''Music/TheRevolutionWillNotBeTelevised'' 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 [[Music/TheSpecials Special A.K.A.]] Just 6 years after the song was released, Mandela was released from prison.
** UsefulNotes/ElvisCostello's ''Oliver's Army'', which name-checked various places that were geo-political hot spots in the late 1970s.
** Just about any song about UsefulNotes/TheVietnamWar.
** Heaven 17's ''Fascist Groove Thang'' is firmly planted in the year 1980, due to mention of Ronald Reagan as 'President Elect'.
*** And, of course, the ColdWar. (''Enola Gay'', ''Dancing With Tears In My Eyes'', ''99 Luftballons'', ''[[Music/{{Genesis}} Land of Confusion]]'')
** Much of the references in political 1980s hardcore punk like Music/DeadKennedys ("Holiday in Cambodia") and Music/{{Minutemen}} ("Viet Nam", "West Germany").
*** Astoundingly, the Music/DeadKennedys' "California Uber Alles" was suddenly relevant again when UsefulNotes/JerryBrown 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 [[UsefulNotes/BarackObama 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.
* Music/WeirdAlYankovic:
** Each of Music/WeirdAlYankovic'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:
*** ''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 NewKidsOnTheBlock parodies symbolizing both the rise of grunge and 80's teen pop acts [[DeaderThanDisco 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.
*** ''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 AmericanIdol 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.
** Al is an odd case - he tended to parody songs that were popular ''two or three years before his album came out'', which means they're usually forgotten by the time his parodies are released. This is the inevitable result of recording times. This has become less of a problem in the modern day, with digital recording techniques and distribution promising a short turnaround -- his parody of LadyGaga's "Born This Way", "Perform This Way", 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 ''Series/{{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.
** "Headline News", from 1994, arguably takes this trope UpToEleven. Like "I Lost on Jeopardy", this was based on a year-old song ("Mmm Mmm Mmm Mmm" by Crash Test Dummies). Here, Weird Al riffed on it by using three then-current tabloid news stories (in song order): UsefulNotes/{{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... member with a knife.
** The song "Tacky", with its references to Instagram, Yelp, selfies, the YOLO (You Only Live Once) motto, and twerking, could almost be seen as "Early 2010s Pop Culture: The Song".
* 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 "[[Music/{{Eagles}} Hotel California]]" and "We Are the World", while his second parodied "[[Music/JohnnyCash 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 Music/EricChurch's "Creepin'" was parodied ''while it was still on the charts''.
** Another example is "Martie, Emily & Natalie", which was a timely takeoff of Music/BradPaisley's "Celebrity" that spoofed the Music/DixieChicks' [[CreatorKiller fall from grace]] in early 2003. The original had a reference to ''TheWeakestLink'' 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'' [[SarcasmMode in no way]] a period piece.
** Similarly, Creator/{{Disney}} put out a "Macarena" version of [[DisneyThemeParks the Tiki Room theme song]].
* Most of those CD compilation albums that are released every year, such as KidzBop 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 Music/TheBeatles 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 TheEighties (heck, ''especially'' TheEighties!) due to the way the technology has evolved.
** And on the subject of TheBeatles, whilst their ''appeal'' is certainly timeless, given they're one of the foremost bands to define TheSixties, they do after a fashion play this trope straight- [[TropesAreNotBad 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 GaitaZuliana group decides to tackle a current issue, it instantly dates itself. This is not only on political songs, but also with mundane themes. "[[http://miqueridagaita.blogspot.com/2010/11/la-parabolica.html 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 TheSixties through the TurnOfTheMillennium -- FolkRock, HeavyMetal, GlamRock, Funk, {{Krautrock}}, NewWaveMusic, Pop rock, HardRock, Electronica, Alt-Rock, with a few other styles thrown in for good measure -- just follow the bouncing [[Music/DavidBowie Bowie]], who helped define some of them in the first place.
* As a {{Long Runner|s}}, Music/RayStevens has done this many, many times in his career.
** 1970: "[[http://www.musicsonglyrics.com/america-communicate-with-me-lyrics-ray-stevens.html 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 UsefulNotes/JohnFKennedy, UsefulNotes/RobertFKennedy, and [[UsefulNotes/CivilRightsMovement 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 NakedPeopleAreFunny. Sure, some people still do it today, but the 1970s was its peak.
** 1986: "The People's Court", a five-minute parody of, well, ''Series/ThePeoplesCourt'' that name-drops original judge Joseph Wapner (who left the show in 1993).
** 1987: "Would Jesus Wear a Rolex" is a ReligionRantSong against the many controversies present in televangelism at the time. Of course, the "megachurch" movement in American Protestant Christianity is [[ValuesResonance 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.

[[folder: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 [[SevenYearRule 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 {{WWE}} (and, to a lesser extent, {{WCW}}) developed a ''WesternAnimation/SouthPark''-like fascination with "hip" topical humor, such as openly mocking the BillClinton/Monica Lewinsky scandal or airing a fake home movie called ''[[TheBlairWitchProject The Blonde Bytch Project]]''. Things have only gotten worse since then, with WWE whipping out the WereStillRelevantDammit card every chance they can get; the low point was probably Vickie Guerrero parodying Creator/ClintEastwood'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.
[[/folder]]

[[folder: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 TheGreatPoliticsMessUp, 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 ScienceMarchesOn, DatedHistory, and other things that can make the "correct" answer just plain wrong.
[[/folder]]

[[folder:Theme Parks]]
* The ''[[Franchise/{{Terminator}} T2 3-D: Battle Across Time]]'' performance at Ride/UniversalStudios 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 reason[[note]]Though the fact that Creator/ArnoldSchwarzenegger's years as the Governator had made him a very controversial figure in California also had something to do with it.[[/note]]; 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 ''Ride/JimmyNeutronsNicktoonBlast'' 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.
* ''Ride/ETAdventure'' is the oldest ride still remaining at [[Ride/UniversalStudios 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 [[DisneyThemeParks Disneyland]] got hit with this ''twice'' during its lifespan. The original park's RaygunGothic vision of the future became outdated within just a decade, causing them to start making updates to the park over the course of TheSeventies and TheEighties. "Flight to the Moon", for instance, became "Mission to Mars" after the Apollo landings. Of course, by TheNineties these visions of the future were also outdated.[[note]]Making matters worse, the Tomorrowland section of the park was plagued with petty crime and youth gangs (most notably the {{goth}} gang Disneyland Arcane Crew) during this period.[[/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 ScienceMarchesOn and TechnologyMarchesOn, 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 ''Film/CaptainEO'' was revived in 2010 due to popular demand, it served to prove that no matter what Music/MichaelJackson fans might think, EightiesHair, synthesizers, and neon-colored aliens and backup dancers are ''not'' timeless [[TropesAreNotBad (though certainly a lot of fun)]].
[[/folder]]

[[folder:Video Games]]
* Due to DevelopmentHell causing the game to be delayed continually since its inception 13 years prior to its release, ''VideoGame/DukeNukemForever'' (released in 2011) has the unintended disadvantage of playing like a game from the early 2000s, right down to its gameplay mechanics and humor. The game plays as though certain parts were only added in a certain decade, the humor is outdated by several years, the references to previous installments are years (and even decades) out of date and the gameplay (as a whole) is much slower than 2010-era FPS's. In additions, several of the "topical references" include an out-of-date reference to ''Franchise/{{Halo}}'' ("Power armor is for pussies!") and a near-exact replication of the infamous Creator/ChristianBale rant from the set of ''Film/TerminatorSalvation'' (which had already been out for several years by the time the game was released). Because of this effect, the mechanics that were added more recently (regenerating health, and Duke only being able to carry 2 weapons at once) stick out like a sore thumb instead of "making the game to today's players".
* ''LeagueOfLegends'' has a character skin dedicated to the GiantEnemyCrab, a meme from 2006. The game is still going strong eight years after the meme and at this rate looks like the last thing on earth that will recall the meme.
[[/folder]]

[[folder:Web Animation]]
* ''Machinima/TheGmodIdiotBox''. Thanks to the creator's tendency to put in references to popular games, memes, trends etc., some episodes of the show can often feel like products of that moment in internet and/or gaming culture:
** [[https://www.youtube.com/watch?v=t6Fpj-tmRiE Episode 8]][[note]]Which was released in Febuary of 2010, but made during late 2009[[/note]], where the entire intro skit is in reference to a Youtube Channel 2.0 layout change that users don't even have anymore. It also has references to 2girls1cup, Will it Blend?, and Fred.
** [[https://www.youtube.com/watch?v=8TqWC2fbG5I Episode 13]] has references to ''VideoGame/DarkSouls'', ''Series/BreakingBad'', and ''VideoGame/TheWalkingDead'' game.
[[/folder]]

[[folder:Web Comics]]
* [[TwoGamersOnACouch Gaming comics]] are like this almost by design, as they often reference then-current games.
[[/folder]]

[[folder:Western Animation]]
* ''WesternAnimation/TheSimpsons'' helped define TheNineties, and episodes from the 2000s are inevitably going to be pegged to future stereotypes given to that decade, too, and [[LongRunner however many more decades the show goes on for]]. FloatingTimeline saves the day again (though with continuity breaking results).
* ''WesternAnimation/SouthPark'' does this to a lesser extent beginning in Season 3, due to the short animation turnaround and their tendency to often use plots RippedFromTheHeadlines. Who even remembers ''spiderholes'' still?
* ''WesternAnimation/FamilyGuy'' 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 BandToon 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 ''Franchise/AlvinAndTheChipmunks'', it is the genre of their music that dates them (or the songs they do covers of).
* ''WesternAnimation/BeavisAndButthead'', in its original incarnation, epitomized TheNineties (back when [[NetworkDecay music videos still aired on MTV]]). With its [[{{revival}} triumphant return]] in 2011, and the focus on some of the shows MTV is now airing (including ''Series/JerseyShore'' and ''True Life'') in addition to music videos, it looks like it's going to try to capture the zeitgeist of TheNewTens as well.
* WesternAnimation/{{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 Literature/HarryPotter releases. Since they use expies, they're not as blatant.
[[/folder]]

[[folder:Other]]
* 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.
* ''Magazine/{{MAD}}'' does this so well that compilation books from each decade since it began in TheFifties 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 [[IstanbulNotConstantinople changing]] [[{{Egopolis}} their names]], things like TheGreatPoliticsMessUp, 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. Early freeways often tended to have very short, narrow, tight ramps not conducive to high-speed travel, and otherwise archaic designs (very few early interchanges provided complete access in all directions), while the 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. 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. 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 PeriodPiece; 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 Creator/OrsonScottCard, ''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 ''Literature/TheBookOfMormon'', 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 StandUpComedy 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 [[http://en.wikipedia.org/wiki/Contents_of_the_Voyager_Golden_Record 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 [[EightiesHair 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 is still under construction.
* [[http://img198.imageshack.us/img198/8480/playboy.jpg This]] (SFW) Brazilian ad for {{Magazine/Playboy}} contrasts 1975 and 2006.
* [[DrugsAreBad Anti-drug crusades]] are dated to particular eras due to the drugs MoralGuardians are worried about. In the '60s and '70s, it was marijuana and LSD. In the '80s, it was crack cocaine. From the 2000s, it's methamphetamine.
* 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.
* [[Wiki/TVTropes This very wiki]]. Given its reliance on informal writing style and pop culture references, it can be made very apparent when a certain entry or article was made ([[ExamplesAreNotRecent 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 ''LightNovel/HaruhiSuzumiya'' or ''Anime/TengenToppaGurrenLagann''.
** Other entries or even pages can be dated with changes in naming conventions (Administrivia/NoNewStockPhrases, tropes named after a character, etc.). While most have been renamed the [[Administrivia/RenamedTropes rename history]], and redirects still show the tendencies of the time.
* You can tell the decade by those recyclable black jokes about famine-struck areas. The same joke would be told in the 1960's about Biafrans, in the 1970's about Cambodians, and in the 1980's about Ethiopians - the words would be absolutely identical, only the location and nationality changed.
** Similarly, you could probably swap references to Darfur in the 2000's with Biafra in the 1960's, since both were breakaway regions beset by genocide.
