Shows set in the future will often have many things we have never imagined, but writers can't resist throwing in contemporary references, or at least references the viewers will understand. How do they accomplish this? Have one of the characters be a self-proclaimed expert of the past, e.g. 20th-century Earth. (Or, for newer shows, 21st-century Earth.)

A common variation (usually played for comedy) is to have [[FutureImperfect the so-called "expert" be completely wrong about some major aspect of his subject-matter.]] This works particularly well when the subject is contemporary society, something that everybody living today knows about.

Contrast with DiscoDan, except these people know they are not actually in the past. Compare with BornInTheWrongCentury, FantasticAnthropologist.

[[folder:Anime]]
* ''Manga/GalaxyExpress999'' episode 28: Tetsuro, a poor kid who's previously shown no signs of knowing any history, meets a man who is trying to grow his beard long and points out that a long time ago, Earth used to have the Guinness Book of World Records.
* This is the ''major motivation'' of the BigBad of ''Anime/{{Moldiver}}''. Professor Machinegal is already rich, famous and respected in his civilian identity; his heists aim to steal "antique" technology, and his favorite part of history is the 1980s (when the series was made).
* Clain from ''Anime/{{Fractale}}'' is obsessed with antiques from before the creation of the Fractale System.
* In ''Anime/CowboyBebop'' much of the information about the past has been destroyed from a gate accident. Still they have one of these in Doohan. He likes to maintain older models of starships and also has in his possession the space shuttle Columbia.
[[/folder]]

[[folder:Comics]]
* Non-futuristic example: In the 1980s, when [[ContinuityPorn Roy Thomas]] was in charge of all the Earth-2 books for DC Comics (most of which were set in the Golden Age), several of the characters in ''InfinityInc'', the book set in present day, were Fans Of The Past. This came in handy when ''Infinity, Inc.'' crossed over with ''ComicBook/AllStarSquadron'', which was set in the 1940s.
* ComicBook/BoosterGold majored in the Age of Superheros in College.
* One subsection of the alien race called the Skrulls in Creator/MarvelComics fell in love with the American style of the 1920s and 30s. Their planet was redecorated to follow this style, and even the Skrulls (shapeshifters that they are) stay in human form most of the time. When the ComicBook/FantasticFour first encountered them, this was the cause of some truly epic CognitiveDissonance.
* The premise for the third continuity of ''ComicBook/LegionOfSuperHeroes'': the entire team was like this.
* A dark version of this trope occurred in the ''ComicBook/RogueTrooper'' story "Fort Neuro". Rogue arrived at the titular fort, hoping to find shelter and some time to let the biochips calm down. However, the stress of holding off a Nort siege for years coupled with isolation due to their sanity slipping, causing the four garrisons to degenerate into {{parodies}} of Napoleonic France, a 50s British seaside resort, a group of disco freaks, and wannabe supermodels. Rogue and the robots eventually managed to knock some sense into them.
* Creator/AlanMoore's ''ComicBook/TomorrowStories'' features the First American and U.S.Angel facing off against Dozier D. Daze and his retro-ray. Daze is obsessed with long-gone pop culture and memorabilia to the point that it's all that gets him hot and bothered. That's right, the man is a latent retrosexual. The First American and U.S.Angel grow increasingly uncomfortable with him turning them into denizens of eras past.
[[/folder]]

[[folder:Films -- Animated]]
* In ''WesternAnimation/TitanAE'', one of the main characters and several minor ones either collect relics of the [[EarthShatteringKaboom destroyed]] Earth, or continue Earth traditions, like football (soccer to Americans).
[[/folder]]

[[folder:Films -- Live-Action]]
* In ''Film/DemolitionMan'', the most popular form of music is 20th-century advertising jingles. Also, Lenina Huxley had such a large interest in the era that her superior referred to it as an addiction.
* Del Spooner in ''Film/IRobot'', though this is mainly an excuse for some crashingly unsubtle ProductPlacement.
* Non-futuristic example: Doc Brown from ''Film/BackToTheFuture'' was always a fan of the [[TheWildWest Old West]] and sometimes felt that he was born in the wrong era; in the third film, he gets to live his fantasy. He nearly gets killed in the process.
* ''Film/MissionToMars'' had a scene early on where a character drove up in a muscle car and was mocked by his electric-car owning colleagues for his antiquated tastes. He defends the internal combustion engine with the air of a modern-day vinyl fan talking to iPod owners.
* An early scene in the 2009 ''Film/StarTrek'' movie shows a young Kirk joyriding in a 20th-century convertible, which his stepfather had apparently refurbished.
* In ''Film/OverdrawnAtTheMemoryBank'' Aram Fingal is a big fan of old pop culture, most notably ''{{Casablanca}}''. This is what gets him into so much trouble.
* In the movie version of Creator/MichaelCrichton's ''Film/{{Timeline}}'', most of the main characters are historians of the medieval era. One of them is a lifelong enthusiast who's trained himself in period-era blacksmithing and swordplay. Early on in the film, he describes the life of a knight and concludes with the mildly {{Narm}}y "The past is ''where it's at!"''
[[/folder]]

[[folder:Literature]]
* Bethany Lindquist of the ''Literature/{{Antares}}'' novels is a historian, and therefore makes frequent references to Earth history. In fact, finding historical parallels to contemporary situations is supposed to be her ''job''.
* The ''Literature/HonorHarrington'' novels have entire ''planets'' whose [[PlanetOfHats entire populations are utterly dedicated to recreating some late-1700s-to-early-1800s Earth society]]. Talk about TheThemeParkVersion, these are theme park ''cultures'', without the tourist industry to justify it. This is what happens when a planetary autocrat decides he's the reincarnation of Frederick the Great. Other than the crazy, he was apparently quite a good ruler - he took his role model seriously. Harrington herself is also a big fan of 20th century naval warfare, and the Havenites Kevin Usher and Victor Cachat are fans of 20th century movies.
** The ancient and honorable art of Grayson swordfighting is ostensibly based on ''The Seven Samurai'' - the founder of the colony was a fan. Naturally, they've filled in some of the blanks over the centuries.
* In the novel ''The Shadow Runners,'' the characters are in Australia, now a prison area in 2176. Rich young scions thrown into Australia are pretty much running the joint, while on loads and loads of drugs. They call themselves "Parliament" and are running around in waistcoats, calling themselves Lord Whatever, and pretending it's VictorianBritain.
* Asimov tends to subvert this by having most of Earth's history long lost in the past in most of his novels. Characters have been known to [[FutureImperfect lump unicorns, orcs and tigers into the same fantasy grouping]]. Nonetheless, there are a few odd examples of fairly accurate history that pops up in unexpected places.
** In ''Literature/TheRobotsOfDawn'' there are a references to some of the robot stories (most notably ''Literature/TheBicentennialMan''), although they're tossed aside as myths.
** In ''Literature/TheCavesOfSteel'', this is called Medievalism, and takes various forms. At one point, protagonist Baley muses that most Earthmen are Medievalists in one form or another. However, some take it much further than others, and Medievalist riots form a major aspect of the plot.
** In ''Literature/TheNakedSun'' there is a Solarian "sociologist" who is incredibly backwards, not even recognizing that mathematics can be used in sociology, who nonetheless knows about Greek history, despite it being more or less forgotten on Earth.
** Perhaps the biggest subversion, though, is in ''Literature/{{Foundation}} and Earth'', where a archaeologist is seeking to find the mythical origin planet, Earth, and ends up following absurd myths about a planet with a massive moon, in a solar system with a planet with a massive ring system, and so on. The bizarre part is that, despite continually going on about how much these things get exaggerated and altered over the years, the actual source material they're working from seems more or less correct, even when it shouldn't be, and they still don't believe it.
* Jherek Carnelian of the ''[[Creator/MichaelMoorcock Dancers at the End of Time]]'' series is his society's foremost expert on the 19th century, [[FutureImperfect which depresses a time traveler he encounters.]] He believes that "19th century" is one language with several dialects, though he does, at least, sort of grasp the concept of trains.
* The protagonist of ''Literature/IAmLegend'', particularly with regards to music. Since the story was set twenty years in the future, it prevents any inaccurate predictions, since the protagonist is the only person left.
* Acts as a ChekhovsGun in the ''Literature/CouncilWars'' series. The re-enactors who're so very interested in the medieval era? Rachel's father, whom she mocks for his unusually ''intense'' interest (though not to his face)? [[spoiler: They keep the world from sliding into complete barbarism, and have the tools - and skills - needed to keep the refugees from starving and succumbing to the elements, and later the skills needed to keep TheDragon from making things even worse.]] For extra points, Rachel's father? [[spoiler: He's actually Charles the Great - a ''legendary'' hero who brought peace to Anarchia for ten years and then vanished, using the name of his brother, Edmund, as an alias.]]
* The obsession with ''Earth's'' past is something of a big deal for the people in the titular world of ''Literature/{{Tranquilium}}''. It doesn't help that Palladia is basically the Russian Empire [-[[RecycledInSPACE On Some Islands!!!]]-], while Merryland, the other big power, is a mix of VictorianBritain and 19th century America.
* Literature/TimeScout: History tourism is a thing. Time guides are basically incredibly competent tour guides who also have Ph.D.s. Time scouts are all IndianaJones.
* Professor Bernice Summerfield from the ''Literature/BerniceSummerfield'' novels is an archaeologist from the future whose specialist historical period is the 20th century.
* In ''Liferature/ReadyPlayerOne'', pop culture of TheEighties comes back into popularity in the [=2040s=], after a game designer wills his vast fortune to anyone who can solve an intricate puzzle revolving around all the things he was interested in when he was growing up back then. People who try to solve the puzzle wind up becoming fans of the past by necessity.
* The gangster Seraffimo Spang in ''Literature/DiamondsAreForever'' is a fan of TheWildWest, and has refurbished a train and an entire town from that era. He is also wearing a cowboy attire when Literature/JamesBond comes face to face with him.
[[/folder]]

[[folder:Live Action TV]]
* Seamus Harper in ''Series/{{Andromeda}}''; he often references culture from our time that confuses everyone else, as he is the only main character from Earth. Examples include comic book references, a desire to learn Gaelic, and surfing (although that seems to still be popular all across the galaxy.)
* Michael Garibaldi of ''Series/BabylonFive'' wasn't obsessed with the 20th century, but he had a great love of 20th century cartoons and motorcycles.
** And also occasionally carries a .38 "slugthrower" which was a gift from his Boston cop grandma.
* ''Series/DoctorWho'' can't avoid this. In the second episode of the series revival of 2005 for example, they go 5 billion years into the future to witness the party that is thrown over the destruction of the planet Earth. And despite the fact that humans have apparently only recently become extinct, somehow the artifacts of remembrance from Earth brought by "the last human" tend to have a suspiciously highly recognizability by someone from the 20th and 21st century (the viewers): the last ostrich egg, an animal that only evolved into existence a few million years ago as of today but apparently is also only recently extinct in 5 billion years, and a 20th century jukebox which plays 20th century music [[FutureImperfect that the last human fallaciously refers to as an "IPod"]]. No artifacts or mentions of technology or animals 10 thousand or 10 million or a billion years in our future, just cultural references designed to be funny to the viewers.
* ''Series/BlakesSeven''. In the episode "Bounty", former President Sarkoff is a student of 'natural history', which has come to mean the study of things that no longer exist. Thus he has 20th Century artefacts mounted on his wall like heirlooms, including gasmasks and cutlery.
* Half of the jokes in ''Series/BuckRogersInTheTwentyFifthCentury'' were based on misinterpreting items from the 20th Century.
* Initially averted in ''Series/RedDwarf'', where the only references Lister made were originally to futuristic sports (like players for various Zero-G Football teams) and television shows (Mugs Murphy), but eventually just gave up and made jokes referencing pop-culture concepts people actually understood. From the beginning though, Rimmer has been a fan of the Napoleonic Age of War.
** Although a lot of the jokes already feel rather dated 10-20 years on.
* ''Series/SpaceAboveAndBeyond'' had a Marine who developed an interest in 20th century rock & roll after studying it in school. The lessons apparently didn't stick, however; he tells his squad that ''[[Music/TheRamones Blitzkrieg Bop]]'' was recorded by Music/PinkFloyd.
* This trope seems to be standard issue on ''Franchise/StarTrek'':
** Tom Paris in ''[[Series/StarTrekVoyager Voyager]]'', though he likes things slightly older than modern day (like '''Captain Proton!''', based on {{Pulp Magazine}}s and serials like BuckRogers and [[Film/FlashGordonSerial Flash Gordon]]). And fixing cars.
** ''[[Series/StarTrekDeepSpaceNine Deep Space Nine]]'' has Sisko and baseball.
*** Odo and O'Brien both enjoy twentieth-century detective novels.
*** Dr. Bashir and Chief O'Brien were re-fighting the Alamo and playing fighter pilots in the Battle of Britain. The station's counselor started to get concerned after a while--other than the battle of Britain, all of their scenarios were unwinnable last stands.
** ''Series/StarTrekTheNextGeneration'' has Picard and the detective program.
*** Not to mention wine making (or at least such is the case with his brother, though considering how steeped in tradition wine making is this may be {{justified|Trope}}.)
*** Data and [=LaForge=] with their Franchise/SherlockHolmes programs.
*** When Worf, Alexander, and Troi go into a holodeck program simulating a town in the "Wild West" of the 1800s, Troi says that she's always been a fan of the (American) Ancient West as her father used to tell her stories about it as a little girl. Her resulting [[GenreSavvy genre savviness]] comes in handy.
*** Another example: when Data is in the holodeck trying to learn how to be comedic, he asks the computer to name the funniest comedians in history. It is revealed that the funniest comedian was a man from the 23rd century whose jokes were based in quantum physics.
** In ''[[Series/StarTrekEnterprise Enterprise]]'', Trip was an old movie buff, and T'Pol knew [[FridgeLogic way more than made]] sense about her great-grandmother's trip to Earth in the 20th century.
** Kirk in [[Series/StarTrekTheOriginalSeries the original series]]
*** In one of the early Star Trek movies, Kirk receives a pair of "antique" eyeglasses as a birthday present (the explanation is he's allergic to some drug that 24th-century people use to treat bad vision -- funny in hindsight since before the end of the 20th century, we were using [[TechnologyMarchesOn laser microsurgery]] to fix eye problems).
*** Marla [=McGivers=] from "[[Recap/StarTrekS1E22SpaceSeed Space Seed]]". Completely justified in [=McGivers=]' case, because she is a historian by profession. Kirk even remarks sardonically upon the discovery of Khan's ship, the ''Botany Bay'', that this will finally give her something to do.
*** Two more examples: During Sam Cogley's closing arguments in "[[Recap/StarTrekS1E20CourtMartial Court Martial]]", he refers to fundamental declarations of rights made in the Magna Carta, the US Constitution, a Declaration of Rights from the Martian Colonies, and the Statutes of Alpha III. Also, references are periodically made to Colonel Green (a dictator from the 21st century) and World War III, as well as the fact that mankind avoided an all-out nuclear war.
*** There are also some examples from the new series, such as a reference to the (future) reunification of Ireland as a result of terrorism.
** Zefram Cochrane from ''[[Film/StarTrekFirstContact First Contact]]'' loves early rock-and-roll. Somewhat justified, as his time period is shortly AfterTheEnd.
** Sulu was suddenly revealed to be a masterful expert on 20th century aircraft in order to {{handwave}} how he could so expertly pilot a 20th century aircraft in [[Film/StarTrekIVTheVoyageHome the fourth movie]].
*** One episode of TOS established that he collected 20th century fire-arms, so an interest in 20th century technology in general is not inconceivable. Also, he was a starship pilot for his entire career, and had pretty much retired by the time of the fourth movie. Maybe he took up flying old-fashioned aeroplanes as a hobby to pass the time?
*** He also showed knowledge of fencing, and while hallucinating from a contagious GRatedDrug called a seeming opponent "Cardinal Richelieu", so clearly ''Literature/TheThreeMusketeers'' (or European history, as the fictional Richelieu was based on a real person) was an influence as well.
*** Young Sulu's knowledge of fencing comes in handier than you might expect in the latest ''Film/StarTrek'' movie ...
** Averted in ''Film/{{Star Trek IV|The Voyage Home}}'', when the 20th-century marine biologist correctly points out that there's at least one thing -- humpback whales -- which no one in Kirk's time will be an expert on.
** Also averted in the second pilot "Where No Man Has Gone Before", where Dr. Dehner reads a poem to Gary Mitchell written on the "Canopius Planet"...[[TwentyMinutesIntoTheFuture in 1996]].
** The strangest thing is that these history fans almost never talk about anything that hasn't already happened. Given, this has made them look silly in the past, but it gets to the point where you feel that no great works of art, philosophy or religion was accomplished after the 20th Century. A rather strange state of affairs, considering that's when we achieve world peace and space travel.
*** They also consider everything before first contact 'ancient' history on several occasions, Voyager especially being prone to this.
*** There are actually several examples in the original series where historical figures, literature, and events are created. Just as one example, in the episode "The City on the Edge of Forever," Kirk talks about a book 100 years to come (relative to 1930) that puts forth the idea that "let me help" is stronger than "I love you."
** The franchise has at least one deliberate attempt at averting this by replacing the expression "third wheel" with "third (warp) nacelle". You can imagine for yourself how silly that sounds, showing once again how TropesAreNotBad.
[[/folder]]

[[folder:Music]]
* The {{Music/TISM}} song "Garbage" is a {{take that}} against the tendency of teenagers to be this for music.
-->Now I know that we should separate our garbage\\
The environment will give us thanks\\
It's going too far when teenagers recycle\\
Their parents' [[{{Wangst}} adolescent angst]].
[[/folder]]

[[folder:Professional Wrestling]]
* Little Jeanne collects tapes from wrestling's past, and like many an old timey wrestler, dislikes jujitsu(though never mentioned Brazilian specifically)
* Old School Oliver John is a fan of old school wrestling, obviously. Specifically, the methodically drawn out flair seen more often in the territorial days.
* The Mississippi Queen Christie Ricci, which is probably a result of her mentor Lelani Kai's influence.
* The New Age Of Old School, Damian Lavaye.[[/folder]]

[[folder:Tabletop Games]]
* Taken to ridiculous levels in ''TabletopGame/{{Traveller}}: The New Era'' (set in the 57th century, referencing 20th century history and popular culture left, right and centre), but justified in that WordOfGod has it that what we're reading is a CulturalTranslation of the 57th-century stuff that's really being referenced.
* A ''TabletopGame/BattleTech'' book of rumors [[LampshadeHanging hung out a lampshade]] on this trope, asking why there were so many references to things 1000 years in the past, and so few from just 200-300 years ago.
* In ''TabletopGame/{{Paranoia}}'', the Romantics are an entire secret society of Fans of the Past. Of course, this being ''Paranoia'', their historical records are [[FutureImperfect badly mixed up]].
* Considered to be a niche market by the crosstime tourist company Time Tours, Ltd., in the world of ''TabletopGame/{{GURPS}} Infinite Worlds.'' "The past, for better or worse, is a specialty interest; the market for The Way Things Should Have Been is limitless."
[[/folder]]

[[folder:Video Games]]
* ''VideoGame/{{Fallout 3}}'' has the "capital preservation society," a museum in Rivet City that displays objects from American history. The curator is enthusiastic, if [[FutureImperfect slightly inaccurate on history]].
* Arthur, a strong Artificial Intelligence whose systems are the basis of the futuristic "biochip" computers in ''VideoGame/TheJourneymanProject'' is described by his creator as having an unfortunate fixation with twentieth century pop culture.
* Inverted in ''VideoGame/MetalGearSolid3'', which takes place in the 1960s, where there are several dialogs with Paramedic in which she comments on the "latest" movies, inventions, and discoveries. Among her claims are that VHS will take off and that scientists have found out that smoking is likely to cause lung cancer. [[ItWillNeverCatchOn Which Naked Snake seriously doubts.]]
--> '''Major Zero:''' "007 is the biggest thing to come out of England since the Mayflower. I wouldn't be surprised if they made 20 more of those movies."
[[/folder]]

[[folder:Webcomics]]
* Memnon Vanderbeam of ''WebComic/StarslipCrisis'' has a particular predilection for the early 21st century: some of the exhibits in the ''Fuseli'' include a copy of ''VideoGame/WorldOfWarcraft'' and the only remaining print of the ''Film/{{Catwoman}}'' movie.
* Tigerlilly Jones from ''WebComic/SkinHorse'' is basically walking personification of TheSeventies, displaying nearly every seventies trope at some point or another, but is disqualified from being a DiscoDan because she was, technically speaking, born in the 1980s. Of course, she ''is'' also certified insane.
* ''WebComic/{{XKCD}}'' has at least [[http://xkcd.com/239/ one]] of these.
[[/folder]]

[[folder:Web Original]]
* The ''Literature/ChakonaSpace'' shared universe is a huge offender in this respect (though some characters ''do'' have good reason to appreciate older music, such as one man who is revealed to be several hundred years old).
[[/folder]]

[[folder:Western Animation]]
* Bouncing Boy in the ''WesternAnimation/LegionOfSuperHeroes'' cartoon was a fan of 20th-century movies. This lets the cast watch a parody of ''Film/{{Alien}}''.
** Earlier continuities had the Legion's financier, R. J. Brande, inspired by 20th century heroes like Superboy ([[FutureImperfect whether or not he actually existed]]). Of course, in some versions of the story, he actually ''lived'' in the 20th century.
** And the post-''ComicBook/ZeroHour'' comics sometimes cast Cosmic Boy as that team's Fan of The Past (and of Superboy).
* In ''WesternAnimation/{{Futurama}}'', Philip J. Fry ''is'' from the 20th century - so, quite naturally, he'll make a lot of reference to the time period he came from.
** He also subverts this on occasion: due to being an idiot, he ''often'' gets things from ''his own century'' wrong (to the point that he fails a 20th century history class). One of the most blatant examples being his total lack of reaction to the idea of traveling in a cruise spaceship called ''the '''Titanic'''''
** The 20th century is more than once referred to as 'the stupid ages' by the cast. In one scene Fry questions their criticism of the 20th century claiming it gave the world the light bulb and the steam engine amongst other inventions. It is duly pointed out to him that those inventions all came from the 19th century.
** Subverted further in "I Dated a Robot" when Fry refers to his time as "boring".
---> '''Professor Farnsworth''': "Boring? Wasn't that the time when they cracked the human genome, and boy bands roamed the earth?"
* Finn, one of the Dark Hand's {{Mooks}} from ''JackieChanAdventures,'' dresses like it's still the 1970's. At one point he actually travels through time [=TO=] the 70's. When it's time to go home he has to be dragged away screaming that he doesn't want to leave.
* Played with in ''WesternAnimation/TimeSquad'' the characters are a million years ahead of us with Larry and Tuddrussel often making references to 20th century pop culture and enjoying soap operas from the 1980's. With Otto it's only natural for him to reference it seeing that he was from the turn of the 21st century. But he's really more interested in the past far from his own, because he's a history wiz.
[[/folder]]

[[folder:Real Life]]
* Lots of people could, if they wanted to, list off enough facts about a past decade or century to fit this trope. Fans of classical music or literature in particular would seem to fit.
* This is at least part of the reason SteamPunk and AlternateHistory exist.
* It's a lot less common for a person to give references on a daily basis to popular culture from what's roughly a three decade period several centuries in the past. "You sing like an early Florence Foster Jenkins."
* Cinephiles. A lot of hardcore film fans will typically have a favorite decade of films that actually shapes their opinions on what they look for in movies.
* [[http://en.wikipedia.org/wiki/Retrocomputing Retrocomputing]]. Huge communities of fans keep maintaining and developing new hardware and software for their [[UsefulNotes/{{AppleII}} Apple IIs]], [[UsefulNotes/{{Commodore64}} Commodores]], UsefulNotes/{{MSX}}s, [[UsefulNotes/ColorComputer CoCos]], [[UsefulNotes/{{TI99}} TI-99/4As]] etc etc etc like there's no tomorrow. Or, rather, like there's no today.
