->''"You could say that any Batman fan writing a Batman comic is writing fan fiction."''
-->-- '''Creator/NeilGaiman'''

When a franchise expands into a {{Long Runner|s}}, themes, ideas, and interpretations will inevitably start being [[AscendedFanon lifted from the fanbase]]. And when a fictional franchise has lasted long enough to [[PromotedFanboy induct its fandom into the ranks of its professional creators]], the same [[{{Fanboy}} devotion]] that produces FanFic will inevitably emerge in the "{{canon}}" material.

Basically, the "inmates" take over the asylum. Sometimes this leads to good things and produces some damned good stories, but other times, the same kinds of motivations and factors that lead to the creation of bad fanfic come into play, to the detriment of the series in general. Sometimes some editors are on hand to curb the worst of it, but other times, things just go OffTheRails.

Note that [[TropesAreTools Tropes Are Not Bad]] still applies here, even though it's trivia.

Not to be confused with the Creator/EdgarAllanPoe short story "The System of [[{{Pun}} Dr. Tarr and Professor Fether]]" or the video game ''VideoGame/BatmanArkhamAsylum'', in which the inmates really do run the asylum. Or with Creator/TheAsylum, a film studio specializing in [[TheMockbuster Mockbusters]].



[[folder:Anime and Manga]]
* The ''Franchise/{{Gundam}}'' franchise is older than many of its present writers, who often grew up surrounded by Gunpla models, and it's started to show. ''Anime/MobileSuitGundamUnicorn'' is a standout example - it's so full of ContinuityPorn that it hardly counts as a standalone series, and it also provides a platform for its writers to [[ArmedWithCanon throw the Federation's morals into question and reinterpret a secondary motivation of a villain from another series]].

[[folder:Comic Books]]
* This happens so often in superhero comics that both Franchise/TheDCU and Creator/{{Marvel|Comics}} [[DorkAge/TheDCU have their]] [[DorkAge/{{Marvel}} own sections]] on the DorkAge page.
* The DCU has been a prime example since the 1980s, at least, when Roy Thomas got handed an entire ''Earth'' of his own, to play around with all of the familiar tropes of FanFic.
** Even before then, Creator/JimShooter began submitting his own layouts and scripts for DC's ''Adventure Comics'' in 1966 at the age of thirteen, writing stories for the Legion of Super-Heroes, of which he was a fan.
** Volume 4 ''ComicBook/{{Legion Of Super-Heroes}}'' comics was infamous for this. Many consider Volume 4 to be the worst, with elements like Element Lad's girlfriend becoming a stalker with a [[GenderBender sex change]] (some fans considered him to be gay), Lightning Lad and TeamPet Proty that revived him 25 years before, and the [[SpinoffBabies teenage clones]] [[TomatoInTheMirror that might not have been clones...]] The next group of writers to take over considered themselves forced to perform the first complete ContinuityReboot of the Legion ever (not even ''Comicbook/CrisisOnInfiniteEarths'' could do that), wiping out all previous history and fan elements. And just to show how much of a BrokenBase the fandom is, the people who liked Volume 4 accused that next group of being the ones doing this.
** Who exactly is Batman's one and only true love? Depends on the author's favorite. Talia al'Ghul is either a near-lunatic woman who raped Batman, a criminal mastermind who happens to have a thing for him and a child by him, or his one and only love who happens to be the daughter of one of his greatest enemies. Comicbook/{{Catwoman}} has nearly the same spectrum, from pure enemy to ally when convenient to true love.
* Several of the primary architects of the Modern DCU are fans of the Silver and Bronze Ages and slowly brought aspects of those eras back into the zeitgeist, retconning just about everything that happened in the DCU since ''Comicbook/CrisisOnInfiniteEarths''. This includes:
** Bringing back the Multiverse with ''Comicbook/InfiniteCrisis'' and ''Comicbook/FiftyTwo''.
** Returning Kryptonite to its multiple colored forms and the various effects it has on Franchise/{{Superman}}.
** Bringing back the original Comicbook/{{Supergirl}}.
** Returning ComicBook/PowerGirl to being Kara Zor-L from Earth-2 instead of an Atlantean.
** Giving Franchise/WonderWoman the Diana Prince secret identity again as a secret agent based in Washington DC (much like the 1970's TV series) and restoring the Amazons to a monarchy under a revived Queen Hippolyta.
** Retconning ''Emerald Twilight'' with ''Franchise/GreenLantern: Rebirth'', reviving Hal Jordan and revealing that Sinestro and amcosmic entity were responsible for Hal becoming Parallax. Of course, even the writer of ''Emerald Twilight'' admitted this was a good move...
** Reviving Franchise/TheFlash Barry Allen in ''Comicbook/FinalCrisis''.
** While not related to ''Crisis'', Creator/GeoffJohns also retconned ComicBook/{{Superboy}} into becoming the clone of Superman and Comicbook/LexLuthor in Franchise/TeenTitans -- which was foreshadowed by a fan letter sent into Superboy's old book... by one "Geoffrey Johns".
** Restoring Barbara Gordon to being Comicbook/{{Batgirl}} and reverting her to her Pre-Crisis backstory (Commissioner Gordon's biological daughter, rather than his adopted niece).
* There is a joke amongst comics forums (and this wiki) that someday fans, unsatisfied with the re-emergence of Silver Age aspects, will become DC writers and set things "right" by "putting things back the way they used to be before all this Asylum Running", which basically translates to "Someday new writers will run the asylum so that instead of the Silver Age, it will be the Dark Age instead."
* From the way he writes [[UltimateShowdownOfUltimateDestiny ultimate showdowns of ultimate destiny]], it's apparent that Creator/FrankMiller likes Franchise/{{Batman}} but not any of DC Comics' other heroes. Still, he is quite aware of the PowerPerversionPotential of certain superheroes and CrouchingMoronHiddenBadass characteristics of characters like Franchise/TheFlash and Comicbook/PlasticMan, and plays those up when he gets the chance to write them (not to mention the PhysicalGod aspects of someone with a Franchise/GreenLantern Ring). The only one he really seems to hate (and whom constantly gets the [[TheWorfEffect short end of the stick]]) is Franchise/{{Superman}}.
* A particularly divisive example of this is ''Comicbook/CrisisOnInfiniteEarths'' itself. Some years after everything went down, it came to light that Marv Wolfman, the man who'd come up with the idea (which the DC execs then signed off on), had been fomenting the essential idea behind ''Crisis'' for a long time... that is to say, ever since he was '''ten years old'''. This has sparked all ''kinds'' of accusations, most of them concerning the idea that the entire DC Universe was allowed to be the plaything of one man's childhood fantasies. This revelation (and the ''incredible'' bad blood it sparked between Wolfman and Thomas, whose own "playground" was removed from existence and relevance utterly) is what essentially sparked the "my continuity is best" attitude at DC, which is still felt to this day.
* Creator/MarvelComics got into this a bit slower (they started five years later), but it's definitely there. Stuff like ''ComicBook/AvengersForever'' is sometimes referred to as "ContinuityPorn".
** ''ComicBook/OneMoreDay'' is a particularly loathed example of Running the Asylum, with editor in chief Creator/JoeQuesada being 24 when Franchise/SpiderMan got married and [[TheyChangedItNowItSucks hating that Spidey got changed from when he was a kid]]. Apparently everyone else who has read and enjoyed Spider-Man within the past twenty years [[NoTrueScotsman don't count as real fans]], since they want the case to be "Spidey grows old and dies off". That was a direct quote from Quesada.
** Quesada also ordered Comicbook/JeanGrey KilledOffForReal and prevents writers from bringing her back. And from some of his own words, including his thoughts that she didn't do anything of merit since saving the universe, Comicbook/{{Cyclops}} is "more interesting" without her.
** Hank Pym (ComicBook/AntMan) was made into a widower after the death of [[ComicBook/TheWasp his wife]], and Quesada claimed he's ''also'' "more interesting" without her. This backfired though, as the Wasp came back and Pym was stripped of the Ant-Man identity in favor of Scott Lang, who is the Ant-Man that stars in [[Film/AntMan the movie]] (though Pym is still present as the inventor of Lang's gear).
** Quesada seems to have some major issues with wives, but not with [[EvenBadMenLoveTheirMamas moms]]; this is why [[Comicbook/FantasticFour the Invisible Woman]] and Comicbook/JessicaJones are spared (the ''ComicBook/SpiderGirl'' continuity's version of Mary Jane used to be on the same boat until [[spoiler:Peter was killed off in ComicBook/SpiderVerse, leaving her a widow]]).
* The famous "Comicbook/TheNightGwenStacyDied" is often accused of being a vehicle for Gerry Conway to [[DieForOurShip kill Gwen so that Peter could hook up with Conway's preferred girlfriend, Mary Jane]]. In reality, a graphic novel compilation of the original Clone Saga says the idea of killing Gwen Stacy was already bandied about when he became the writer, and he was simply the guy who executed it. He admits that he thought Mary Jane was a better love interest for Peter, but more the point, felt that the death of beloved Gwen Stacy would be another defining moment for a character defined by tragedy. As he says, "tragedy and pathos are meat and potatoes to a guy like me."
* ComicBook/{{Cyclops}} is often a victim of this trope too. While he's never been the most popular X-Man (he's always had at least a decently large fandom, but he has an even larger {{hatedom}}... and used to also have a lot of readers just bored by him, but thanks to this trope he's more divisive than ever), the main reason for those who dislike him stems from the way [[TheBusCameBack he was written back into the comics]] after leaving to be with his new wife and son. Because of a writer who was a fan of the original five, Cyclops and Jean were returned and reunited, but while it wasn't NEARLY as cut and dry as many remember it, it basically involved Scott leaving and through a series of convoluted events was unable to find his wife and son, believed them dead, and so resumed a relationship with Jean. Because of THAT, there's many people who now hate him, and it affected how he was written. Some writers deliberately write him as unlikable because they dislike him, and because of others reading him like that, it caused his character to be degenerated quite a bit by some writers.
* While we're at it, let's consider ComicBook/{{Wolverine}}'s ridiculous PowerCreepPowerSeep over the years--his HealingFactor going from a simple neck wound being potentially lethal to coming back [[FromASingleCell from being burned down to his adamantium bones]]--and consider that this is what happens [[PopularityPower when childhood fans join up and power-boost their favorite character]].
* For both DC Comics and Marvel Comics, you can identify the age of many writers by checking what characters are their favorites, assuming they were last famous when the writers were between 12 and 16, and doing the math.
** Brad Meltzer: Comicbook/{{Vixen}}, ComicBook/RedTornado, Dr. Light.
** Robert Kirkman: Onslaught, Comicbook/{{Cable}}, Stryfe. ''Anime/DragonballZ'' also has a distinct influence on ''Comicbook/{{Invincible}}''.
** Creator/GeoffJohns: mid-1980's Roy Thomas and Alan Moore work for DC.
** Ed Brubaker has said many times in interviews that the first two comics he bought with his own money were [[Comicbook/ImmortalIronFist Iron Fist]] and an issue of Comicbook/CaptainAmerica featuring the Evil '50s Cap as a villain; in his later career, he revived Iron Fist in a new solo title and, while writing Comicbook/CaptainAmerica's solo title, brought back Evil '50s Cap. Both these runs are widely acclaimed, [[TropesAreNotBad so this is one of the good examples]]. He also has said that one of the few issues he still has from his youth is one of Steranko's, when Cap "died" for the first time. Not only has he based his entire 50+ issue run on the three Steranko issues, he also "killed" off Cap--to much critical and fan acclaim.
* Creator/JephLoeb has been pretty apparent for this with his ''Comicbook/SupermanBatman'' series and the "Hush" arc of Batman (putting characters in with no explanation).
* ''Comicbook/SonicTheHedgehog''[='s=] head writer as of this writing (December 2016) is Ian "The Potto" Flynn, a [[BigNameFan somewhat well known fan of the series]], who was even writing his own Sonic fan comic ("Other M") prior to being picked up by Archie. This was met with a mixed reception that largely depends on where on the Internet you go; of course, this ''is'' [[BrokenBase the Sonic fandom]]. Some complaints include ignorance of canon and derailing several characters, some of which were to preserve certain relationships (namely Sonic and Sally's). Some things he's gotten a more positive response for, however, have been [[AndThereWasMuchRejoicing his killing off very unpopular characters]], rewriting bad stories, cleaning up unresolved plot points, and offering other related fanservice to the fanbase. One of his most notable contributions has been citing a lot of Sonic Internet memes and other memorable lines from various Sonic media. It helps that his writing and understanding of the characters and source material has improved a ''lot'' since he started out with the gig, and the post-''Worlds Collide'' timeline reset cleaning up much of the messy comics-only material and moving it the comics closer in line with the games, due to the legal mess surrounding Ken Penders.
* Speaking of Ian Flynn, he also wrote the ''Comicbook/MegaMan'' comic (until the indefinite hiatus) to incredible acclaim with an impressive AdaptationExpansion (including quite a few original characters who are mostly loved by fans), displaying an incredible understanding of the source material. It's not hard to find people who can remark that the Mega Man comics are some of the best-written comics they've ever read in recent years. Unfortunately, Archie's financial troubles mean that we won't see more of this anytime soon, as far as we know.
* ''Franchise/{{Transformers}}'' comics suffered from this during their revival by the now-defunct [[ComicBook/TransformersGenerationOne Dreamwave Comics]]. Under Dreamwave, plots tended to be either simple or vague while the authors took time to work in [[FanWank explanations for the toys with rub signs]] and rampant {{Easter Egg}}s that contributed nothing to the story. It didn't help that they essentially just built off the old kid's cartoon from the '80s.
** On the other hand, fans have had no problem with Nick Roche and James Roberts, who made a short ContinuityPorn story that [[AuthorsSavingThrow uses elements]] [[ArcWelding of McCarthy's run]] to turn Prowl into a bona-fide MagnificentBastard, and created new, likable personalities for a half-dozen characters in ''ComicBook/TheTransformersLastStandOfTheWreckers''. Roberts continued the process in ''ComicBook/TheTransformersMoreThanMeetsTheEye'', giving major screentime and development the fans enjoy to even more characters who previously had little to no exposure.
* Creator/ReginaldHudlin is a fan of ComicBook/BlackPanther. After he started to write his adventures, T'Challa was turned into a GodModeSue, Wakanda into MarySuetopia, and ComicBook/{{Storm}} from ''X-Men'' [[TokenRomance married BP]]. Afterwards, wherever the two go, everyone else immediately gets hit with {{Idiot Ball}}s.
* In ''ComicBook/{{Daredevil}}'''s case, it seems like all the best writers that get their hands on him (including Creator/AnnNocenti, Creator/KevinSmith, Creator/BrianMichaelBendis and Creator/EdBrubaker) are fans of Creator/FrankMiller's run and, just like him, are trying to make Matt's life [[TheWoobie as miserable as possible]]. The Punisher is ''supposed'' to be a dark and brooding character, [[TropesAreNotBad so fans don't mind]]. Tellingly it became divisive when Mark Waid [[LighterAndSofter wrote stories whose endings didn't drive him to drink from despair]], though Waid still has fans for the run.
* Artist example: ask Lenili Yu to draw a scene with multiple superheroes, or large battle with them. The odds of finding his favorite character, Comicbook/HowardTheDuck, in it, even if he wasn't mentioned on the character list, are equal to or greater than 100%.
* ''Comicbook/ElfQuest'' became almost entirely run by fans after the first few storylines, and the original creators (Wendy and Richard Pini) never seemed to particularly care about the quality of the new art or writing - but still declared all of it canon. Some of the fan-made comics are seriously great. Most of them are not. Examples:
** Kahvi is Two-Spear's daughter, and magically got amnesia after she fell into a magic pool, and all of the Go-Backs are "cleansed" Wolfriders who apparently forgot to tell Kahvi or their own children or anyone at all about their heritage. Kahvi learns about this from Egg, who was rescued by Two-Edge, and Egg gets a snake for a bracelet. Also, Kahvi desires Cutter to an unhealthy level, so she tries to kidnap him and almost succeeds because all of the elves are suddenly on the wrong continent for no apparent reason. And Tyldak does slapstick.
** When he was a kid, Cutter was a slave for the trolls for a full year, and yet he doesn't know what the caverns he lived in looked like. The reason? They made him wear a blindfold.
** When he was a kid, Skywise met Timmain...and then he forgot about it again.
** There's this really tall white-haired elf in the future named Jinx who has a lot of sex with humans and talks to reptilian aliens and can teleport.
* In an interview with Comic Heroes, a British comics industry magazine, Creator/AlanMoore essentially said he despised this trope and blamed it for many of the reasons comics have the reputation they do today. He also said he may retire from the industry due to this trope, but it doesn't seem to have occurred yet. Given that nearly all of his best-known works, including ''League'', are based on someone else's creations, there is some small hint of irony in his comments.
* This is true of ''Comicbook/TheBeano'' and ''ComicBook/TheDandy'', with many of those working on the comic having read the comic as children. Seeing as the comic started in the 1930s, this was true even in the early days, with one of the co-creators of ComicStrip/DennisTheMenaceUK having even read ''Comicbook/TheBeano'' [[http://www.guardian.co.uk/news/2007/sep/20/guardianobituaries.pressandpublishing as a child]].
* The writer of ''Amazing Franchise/SpiderMan'', Dan Slott, has been a rather [[BrokenBase contentious]] example of this. Being a [[AscendedFanboy self-professed Spider-Man fanboy]], his run post-BND brought critical acclaim to the series, shooting the franchise up the sales charts and [[ComicBook/JMSSpiderMan mirroring the success of JMS's previous run.]] With that said, Slott ''also'' [[TrollingCreator developed quite the reputation with his detractors]], [[DearNegativeReader arguing with his critics on message boards]] and even going as far as [[TakeThatAudience making jabs in the comic itself.]]
* ''ComicBook/MyLittlePonyFriendshipIsMagicIDW'': Both Andy Price and Katie Cook had plenty of G4 fanart on their Website/DeviantArt pages before the series was announced, and Katie has said she was a fan of the original G1 series. This leads to such things as Derpy being featured prominently and being fond of muffins, “flank” being used as a synonym for “butt,” etc. Amy Mebberson, Heather Nuhfer, and Heather Breckel were also all big fans before working on the comic. Pretty much everyone involved is a brony/pegasister!
* The unusually violent and over-dramatic "Home Schooling" arc of ''ComicBook/{{Runaways}}'', in which Old Lace [[spoiler:appears to die]], Klara Prast is transformed from a relatively inoffensive CousinOliver into an annoying brat with uncontrolled powers that threaten to destroy the team, and Gertrude Yorkes suddenly reappears out of nowhere, starts to make sense in some sick way when you read series editor Nick Lowe's comments announcing the run, where he promotes the arc as being the best one since the one where Gertrude Yorkes died. One might surmise that Lowe was one of those fans who subscribed to the theory that Klara was a ReplacementScrappy for Gert. Unfortunately for all ''Runaways'' fans, Marvel apparently realized that the inmates had taken over the asylum and decided to shut it down more or less permanently in 2009.
* Both Ed Brubaker and Rick Remender have done this towards ComicBook/CaptainAmerica's sidekicks. Both [[ComicBook/TheWinterSoldier Bucky Barnes]] and ComicBook/TheFalcon, respectively, have had their lackluster CListFodder status upended (both the fact that Bucky WAS C-List and Falcon's UnfortunateImplications-laden retconned past) and were both turned into Captain America at some point or another, with positive results.

* ''Franchise/StarWars'' as well; a lot of ExpandedUniverse writers started turning their favorite characters into {{Mary Sue}}s or TheWoobie, or otherwise derailing characters to fit their own fantasies. Popular targets in ''Franchise/StarWars'' include Luke, Mara, Boba Fett, and [[BadassNormal Talon Karrde]].
** Dr. Curtis Saxton became a technical adviser for the prequels and wrote the ''Incredible Cross-Sections'' supplemental books for Episodes II and III entirely because of the impressive detail of his website, "The Star Wars Technical Commentaries". Of course, it probably helps that he not only has a [=PhD=] in astrophysics, but also that his doctorate thesis paper was essentially Version 1.0 of his website. However, he has received criticism that his works on the ''Incredible Cross Sections'' don't really match up what we see on-screen, and in fact overshoot them by several orders of magnitude. His more visceral critics flat out accuse him of [[ArmedWithCanon trying to rewrite canon to win a fan debate]].
* The ''Film/ResidentEvil'' movies have canon characters that appear ending up playing second fiddle to the film's protagonist, played by the writer-director's girlfriend/wife. A blink-and-miss newspaper clip of an "Officer Kennedy" being shot and killed, in any other series, would be a joke, but it just ends up infuriating when it's clear it was done from keeping any ''canon'' character from stealing the CreatorsPet's spotlight.
** Since the series is up to its sixth entry, it's confirmed that the ''only'' canon R.E. character to get any real dignity next to Alice is Albert Wesker, the BigBad of the series. Contemporary entries into the games also affect the movies as well, such as the Plagas and elements from ''Resident Evil 5'' being introduced in a setting that ''never brought them up''. Any canon character who is lucky enough to come back after the film they were introduced in still finds themselves without a point, even the games' most popular character Leon S. Kennedy, who somehow must have survived that fatal shooting...
* The timeframe is relatively small, but the ''Film/DeathNote'' movies fell victim to this. In the film universe, the fan favorite L has a much firmer grip on the plot and greater impact on the ending. Then there's the entire original sequel in which L acts out various scenarios which seem to exist solely to fit the format "wouldn't it be awesome if L saved/met/ate/rode around in a _____?"
* ''Film/SupermanReturns'' is a textbook example. Creator/BryanSinger, who at that point had turned the [[KudzuPlot extremely convoluted]], SpaceOpera-esque ''Comicbook/XMen'' universe into two down-to-earth, accessible and critically acclaimed hits (''Film/XMen1'' and ''Film/X2XMenUnited''), was hired on the assumption that he'd do the same with Superman. The important difference was that Singer was initially not an ''X-Men'' fan at all, and thus understood what other non-fans (i.e. millions of movie-goers) would find compelling about the source material and made the movies around that stuff. ''Film/SupermanTheMovie'', on the other hand, was one of his favorite films, and thus the franchise-making blockbuster he was entrusted to deliver wound up as some sort of vague sequel to films that came out 30 years earlier, PACKED with [[ContinuityPorn dozens of quotes and forced homages]] to said films in lieu of new material, and a bizarre plot featuring [[spoiler:Superman as the absentee father of a maybe-half-Kryptonian child which Lois might not remember conceiving depending on whether or not he erased her memory of their affair from either version of ''Film/SupermanII'', prior to the events this film, which they don't explain]]. It did not go over well, and a [[Film/ManOfSteel reboot]] began just seven years after ''Returns'' came out.
* Whit Anderson, the writer for the ''Film/BuffyTheVampireSlayer'' ContinuityReboot, is a fan of the Creator/JossWhedon [[Series/BuffyTheVampireSlayer series]]. He was the same age as Buffy when the show was first running.
* When Nicholas Meyer heard that Sulu's first name in the ''Franchise/StarTrek'' books was given as "Hikaru," he liked it so much he had Sulu use it in his Captain's Log for the USS Excelsior in ''Film/StarTrekVITheUndiscoveredCountry'', thus cementing it as part of the Star Trek Universe.
** This later happened to Uhura, whose first name was never given in canon until [[Film/StarTrek the 2009 movie]] revisited her character. "Nyota" was chosen out of several competing names from the ExpandedUniverse. "Nyota" being the preference of Creator/NichelleNichols pretty much sealed the deal.
* ''Film/KingKong2005'', like ''Film/SupermanReturns'', is a prime example. While Creator/PeterJackson was a fan of ''Film/TheLordOfTheRings'', and still managed to turn them into humongous hits, the [[Film/KingKong1933 original 1933 version]] of ''Film/KingKong'' is his all-time favorite film. He had wanted to remake it as a young boy, and even planned on doing it before adapting the LOTR films (it took the latter becoming the mega blockbusters that they are to finally convince the studio to fund it). Needless to say, the film ended up being packed with loads of plot points, MythologyGags, and character quotes that only people who were familiar with the original would pick up on; the film also ended with a running time of ''three and a half hours''. While the film isn't seen as ''bad'' and it wasn't even a failure at the box office, it didn't become a mega-success like the LOTR trilogy, and some blame Jackson's closeness to the original as one of the reasons it failed to match the quality of his previous work.

* Since at least the fourth book, Piers Anthony's ''Literature/{{Xanth}}'' series now consists almost entirely of puns and {{plot coupon}}s taken from reader fan mail--and there are ''over 30 books''. The further into the series you go, the more reliant the books get on reader-submitted puns. He even gives credits in his Author's Note at the end of each book for each reader suggestion he decided to use. It's a shame, as Anthony has demonstrated his writing skills in numerous other series, but it may say something about the potential audience that the ''Xanth'' books have always been his most popular.
** The frustrating part is that Anthony tried GrowingTheBeard with the ''Xanth'' books around the mid-teens, and it worked for a few books. Then around book 20, he seemed to give up trying to write stories, and just strung the thousands of puns he's sent together and called them books. It's likely he realized that coming up with some characters and a plot outline and having the characters 1) meet someone new every chapter, 2) do a full round of introductions and a story recap to that new person, and 3) just wandering from reader-submitted pun to reader-submitted pun in between was a much easier way to meet his word count and get his paycheck than bothering to write a story.
* Creator/HPLovecraft went off and encouraged fans of his work to do this. In fact, he read most of his fanfiction, and on a few occasions even ''expanded'' off his fanfiction. Note, though, that this was around eighty years ago and his fanbase was relatively small, so most of his fanfiction came from respectable authors.
** This is basically how the Literature/CthulhuMythos works. The original circle of writers is long-dead, and so the fans of each successive generation of contributors start contributing stories to the mythos, thus becoming the new generation of writers. In fact, much of Lovecraft's work is derived from other authors, such as Ambrose Bierce, meaning that the Lovecraft circle ''themselves'' were a case of this trope.
* The Apocryphal Books of the Bible (Ezra 2, 3 and 4 and Isaiah 2 and others) read much like fan-fiction. Instead of the structures found in the originals, such as common poetic forms and language (which is often repetitive and dry), these books constantly reference the more 'exciting moments' from those books. Lengthy depictions of giant apocalyptic battles between good and evil are extremely common. They are often excluded from many Biblical Canons for this reason.


[[folder:Live-Action TV]]
* ''Series/DoctorWho'':
** In the Classic series: Creator/MatthewWaterhouse, a literal card-carrying fan (he belonged to the Doctor Who Appreciation Society, the biggest ''Who'' fan club in the world), was cast as TheScrappy, Adric. Around the same time another fan, Andrew Smith, had a script accepted. A few years later the überfan Ian Levine co-wrote a (poorly-received) script for "Attack of the Cybermen" (as well as writing the music for ''K-9 Company'', a OneEpisodeWonder SpinOff). In the late '80s came Andrew Cartmel, a young and inexperienced--if wry--writer who got the gig of Script Editor just by applying. The result was three years of {{retcon}}s, postmodern commentary both on the show itself and its fanbase, and the most convoluted storylines ever. Opinions are deeply divided on this era. To some extent, though, it's never really gone away. Technically, Cartmel had more of an interest in ComicBooks, particularly the work of Creator/AlanMoore, than in ''Series/DoctorWho''; however, two of his writers, Marc Platt and Ben Aaronovitch, ''did'' consider themselves fans (only because Ben didn't really know what a "fan" was), the former having contributed articles to the fanzines of the day and the latter contributing two very "fannish" stories. Behind the scenes, the three of them also came up with the "Cartmel Masterplan", a secret {{backstory}} {{retcon}} of the Doctor's history, which never quite found its way to the screen.
** In the 1980s, a then-unknown Creator/NicholasBriggs and some other fans created an audio series called the ''AudioPlay/DoctorWhoAudioVisuals''. They eventually went pro, founded the official audio series AudioPlay/BigFinishDoctorWho, and adapted many of their old FanFic stories into proper audio episodes, which are ''still ongoing'' with Briggs as the ShowRunner. Creator/NicholasBriggs also managed to cast many of the Doctors and their companions in his unrelated TV and film works, and currently voices the Daleks and the Cybermen in the TV show.
** The revival series had this from the get-go; Creator/RussellTDavies, naturally, was a huge fan. Current showrunner Creator/StevenMoffat is also an überfan. The Tenth Doctor, David Tennant, has even stated in interviews that wanting to play the Doctor is what led to his choice of acting when he was young. Creator/PeterCapaldi is also a huge fan, and upon taking the role of the twelfth regeneration of The Doctor, he almost immediately argued with Moffat over problems with the scripts.
** Going by the Appreciation Index for certain episodes from both writers, [[TropesAreNotBad this may not have been bad]] for the new series. Moreso when you remember the 1999 Children In Need Special (fanfiction if anything is), starring Rowan Atkinson and Hugh Grant as The Doctor, was written by that same Steven Moffat.
** As ''Series/DoctorWho'' has been on the air more or less continuously for half a century and has been one of the consistently most popular shows in Britain for that entire time (minus a decade or so), pretty much the only way to avoid having fans running the show is to deliberately select people who hate the show. Or who have spent the last fifty years in a barn.
* Creator/StevenMoffat and Creator/MarkGatiss of ''Series/{{Sherlock}}'' describe themselves as Arthur Conan Doyle fanboys and it shows. The duo's talent made the series an aversion as it was critically acclaimed and beloved by book fans and newcomers for its {{in joke}}s and {{Shout Out}}s [[MythologyGag to the original stories]], fascinating explorations of Sherlock's mind, and [[ShipTease teasing]] [[FanPreferredCouple Johnlock]] so directly that actually happening seemed possible. But with the beginning of series three, the very same elements became so overplayed that it ruined the show. [[MythologyGag References]] became more integral to the plot, applied to fanon as well, and were tweaked to throw book fans off the mystery, ruining the fun in catching the reference and mostly confusing the plot. Mysteries became overly complicated, ended with nonsensical twists, and were excessively bleak and over dramatic. Exploring Sherlock's mental state was made so important that the mysteries and even antagonists would eventually revolve around him. The writers began to resent the fans paying Johnlock so much attention and began to openly mock them for it, driving away even hardcore shippers. That so many of these criticisms also apply to Moffat's run on Doctor Who has only exacerbated complaints.
* ''Franchise/StarTrek''
** Creator/{{CBS}} and Pocket Books encourage fan-fic writers to aim for more legit careers with the annual ''Strange New Worlds'' short story competition.
** Season 4 of ''Series/StarTrekEnterprise'' merits special mention here. The producers of every modern Trek show (and some actors, most notably Tim Russ and Jolene Blalock) have been ''fans'', but S4 showrunner Manny Coto was a ''fanboy'', and the season he created was the sort of ContinuityPorn you either love or hate. In fact, ''Enterprise'' in general deliberately harks back to ''The Original Series'' (both in time frame and in the less than ensemble cast), alienating fans who started watching during ''The Next Generation''.
** In ''Series/StarTrekTheNextGeneration'', Ronald D. Moore became a promoted fanboy entirely by chance when his then-girlfriend (who also happened to be a set dresser for the show) gave him a tour of the studio and he had an opportunity to present the producers a fanscript he had written. Not only did the fanscript become an actual episode, "The Bonding," but Moore became one of the largest contributing writers of both ''The Next Generation'' and ''Deep Space Nine'' and wrote many of the best episodes of both series (often collaborating with other talented writers who had different styles, such as the MindScrew-loving Brannon Braga and "anti-fanboy" Ira Steven Behr). Moore later created a series of his own: ''Series/{{Battlestar Galactica|2003}}''. Needless to say, he seems to be an especially talented PromotedFanboy.
** [[AvertedTrope Apparently]], J.J. Abrams was chosen to be the creator of [[Film/StarTrek the new movie]] because he was only a ''casual'' fan of the series. (While Abrams was admittedly a casual fan, his colleagues and screenwriters Alex Kurtzman and Roberto Orci are themselves admitted fanboys.)
** Gene Roddenberry is said to have encouraged ''Next Generation'' writers ''[[HalfRememberedHomage not]]'' [[HalfRememberedHomage to catch up on the original series]]; he didn't want the new show trying to imitate the old.
** [[http://stardestroyer.net/Empire/Essays/BrainBugs.html This admittedly pro-Star Wars fan]] illustrates a theory of how this might have happened to Star Trek canon. And in case anyone still thinks "Asylum" is too strong a word, this article exposes a downright schizoid trend of growing [[EpilepticTrees strange stuff]] out of initially innocuous details.
** Even ''Series/StarTrekTheOriginalSeries'' had some of this. Although Roddenberry initially hired professional science fiction authors to write a lot of the early stories, several fan scripts were accepted and produced in the second and third seasons, among them "The Trouble with Tribbles", "The Empath" and "The Lights of Zetar". "Who Will Guide the Blind" by Judy Burns and "Remote Control" by Jacqueline Lichtenberg are well-known fan scripts which their authors would have submitted for a fourth season if there had been one.
* ''Franchise/PowerRangers'' has fans, too. The tenth anniversary season, ''Series/PowerRangersWildForce'', promoted long-time fan Amit Bhaumik to head writer status. Reactions are split: the season itself is considered abysmal, but that has just as much to do with Disney's buyout of the franchise and the cast and showrunner Jonathan Tzachor as the writing staff or anything else. On the other hand, there are the two (completely original) [[ReunionShow team-up specials]]. The traditional previous/current season cross is considered one of the best the franchise has to offer, as not only does it bring back a very popular cast, it also provides closure for the season's villains, manages to integrate the two teams almost seamlessly, and even provides some ShipTease: not only can [[ActionGirl Jen]] and Wes have a happier ending than previously thought, but so can ''TF's'' [[SixthRanger Eric]] and ''WF's'' Taylor. Meanwhile, the tenth anniversary special, despite being a banned topic on many message boards and ripping open plot hole upon plot hole, is still plenty entertaining, between the various {{continuity nod}}s and well-choreographed fight scenes. Notably, it also features a reference to a fan hoax known as "Scorpion Rain," which Bhaumik helped perpetuate; he noted that he wrote "Forever Red" as if "Scorpion Rain" was in continuity. See the {{fanon}} page for details.
** Tzachor is also an example of this, because he's a fan of...Franchise/SuperSentai, which led to him making the seasons he directed [[ShotForShotRemake cleave as closely to their source material as possible]]. This attitude of course clashes with directors who want to write original stories that respect Super Sentai without slavishly imitating it; the disagreement over these attitudes led to previous head writer Judd Lynn quitting at the end of ''Series/PowerRangersTimeForce''.
* The whole ''Franchise/{{Stargate|Verse}}'' franchise, sort of. Some of the people working on it apparently hung out on fan forums and possibly got a lot of ideas there. There are even episodes with alternate universes or time lines in order to throw in some popular relationships or events that don't fit into the normal storyline (most of the characters in SG-1 are in the Air Force and so can't have romantic relationships). Fans pointing out mistakes also caused things to get changed, such as the steps of the gate room in Atlantis, which displayed Ancient writing with some lines out of order and upside down. It turns out they had already been fixed, but were "fixed" again in response to forum threads and ended up having to be rearranged some more. Who knows if they ever got it right. But after the fans started figuring out how to read the alien text, the art people started hiding messages. This may be more like PanderingToTheBase, except that they were in direct contact with the fan community.
* Several episodes of the 6th season of ''Series/XenaWarriorPrincess'' were written by a (critically acclaimed) fanfic writer who was approached by the creators of the show and asked to write a bunch of episodes.

[[folder:Newspaper Comics]]
* A rare example from the funny papers. Jeff [=MacNelly=] originally drew and wrote ''ComicStrip/{{Pluggers}}'' himself, but after readers began submitting gags, he changed the strip so that ''all'' of the gags were submitted by readers. The trend continued when [=MacNelly=] handed the strip over to Gary Brookins in 1997. (After [=MacNelly=] died in 2000, Brookins and Chris Cassatt took over on his other strip, ''ComicStrip/{{Shoe}}''.)

[[folder:Professional Wrestling]]
* Wrestling/{{ECW}}, from Wrestling/{{Paul|Heyman}} [[DrinkingTheKoolAid "Drinking the Kool-Aid"]] [[Wrestling/PaulHeyman Heyman]] to PromotedFanboy "Loose Cannon of Commentary" Wrestling/JoeyStyles. (Although Heyman is generally regarded as a good booker... just a terrible businessman, and Styles is considered a fine commentator, if one with a reputation of not wanting to play ball with the WWE (however justifiably)).
* Wrestling/KevinNash had a stint as head booker in Wrestling/{{WCW}} towards the end of its existence, and many saw it as a vehicle that he used to get himself over and knock down a few undercarders along the way. However, this is more of an exception rather than a rule; wrestlers have served as head bookers in the past and don't often make the product about themselves. Wrestling/DustyRhodes is a key example, as his booking is generally regarded as worthwhile even if he was also in the product itself at the same time.

[[folder: Tabletop Games]]
* ''TabletopGame/{{Exalted}}'' does this religiously; multiple current writers for the line got their start creating fan works on the official forums. In a case of [[TropesAreTools Tropes Are Not Bad]], the main block of them (the Ink Monkeys) are often liked ''more'' than the original, professional authors. (Though not universally, of course - fanbases always split.) For the culmination of the trope, they composed the team that patched up balance issues of the Second Edition (known as "Exalted 2.5") and were involved in writing the entirety of Third Edition.
* ''TabletopGame/DungeonsAndDragons'' has several reasons for this even aside from HouseRules tradition meeting Internet communities. "[=3rd=] party" supplements having [[InNameOnly little to do with]] established canon on any issue are okay, and in the D&D3 era even inevitable (due to the OGL). Development for settings dropped while switching to new editions was taken over by fan communities, as some sort of {{Abandonware}}. The new generation of designers ran free, even through [=WotC/Hasbro=] {{sourcebook}}s are supposed to be {{canon}}. A good thing for uncharted areas, but all too often it isn't expansion, but walking over established parts so obliviously you almost hear "{{Squee}}!" from the page. Things could have gone smoother if this didn't coincide with the time when focus shifted from modelling specific settings to expanding universal rules. Fan enthusiasm knows no limits.
** Much of the Arthaus product line for the ''TabletopGame/{{Ravenloft}}'' D&D setting was authored by former members of the Kargatane, a team of fans responsible for the Ravenloft fandom's first major website, netbooks, and fanzine.
** ''TabletopGame/DarkSun'' and ''TabletopGame/{{Spelljammer}}'' were taken by their respective online fan communities, expanded and d20-adapted.
** Kobolds' draconic [[PowerCreepPowerSeep upgrade]]. Uncalled for, since they already had their cozy little niche and in hands of a good GM were viable [[NotSoHarmlessVillain or even dangerous]].
** The great shoehorning epidemy. Symptoms: a new feature is accompanied by instructions how to stick it ''everywhere'', whether the target has a place for it or not. During the outbreak, it was a safe bet that a new "Pearl Diver" class would contain the ways to use it in every existing setting... even desert ones.
** A variety of stuff, sometimes [[{{Animesque}} weird]], is brought in by fans of other works whether it makes sense -- as in, "we need some huge space monsters in ''TabletopGame/{{Spelljammer}}'', let's add a giant turtle with a wink to ''Franchise/{{Gamera}}'' -- or not -- as in...
*** ''Magic of Incarnum''? Fans [[http://wiki.rpg.net/index.php/File:MPost16542-Incarnumposter.jpg noticed]] exactly [[TheForce what]] it was about.
*** When the new generation of developers sometimes can't even make up a good name, we have books named after artifacts from earlier editions, or something like [[http://index.rpg.net/display-entry.phtml?articleid=2651 this]] Magazine/{{Dragon}}: ''[[TabletopGame/GeistTheSinEaters Sin Eaters]] of Eilistraee'' (from one of ''[[http://index.rpg.net/display-entry.phtml?mainid=411 Lords of Madness]]: The Book of Aberrations'' authors). Nope, not an April issue.
** ''TabletopGame/{{Pathfinder}}'' is essentially 3.5e as written by the former publishers of ''Magazine/{{Dragon}}'' magazine, and has a great number of popular house rules already baked-in.
** 5th Edition is a return to form in many ways, making this something of a CyclicTrope.
* ''TabletopGame/MagicTheGathering'' turned this trope into a point of prestige. Fans that are good enough to win the Worldwide Invitational are able to design a card for a future set, [[http://mtg.wikia.com/wiki/Invitational_Cards some of which turn out to be quite good]].
** Not to mention, many of the people involved in making the game, up to and including Head Designer Mark Rosewater, were players of the game before being hired by Wizards of the Coast.
* This is the entire point of ''TabletopGame/{{Legend of the Five Rings}}''. Winning (and, sometimes, losing) Tournaments has explicit story consequences that range from choosing a bride for a particular character, to choosing who gets to be the new Emperor. This has varying effects on the story's quality based on whether the tournament winner cares much about narrative consistency, or just wants to annoy the writers. In one infamous case, an entire story arc was derailed by the Honorable Dragon Movement, a group of players who refused to play corrupted decks in an era when the Dragon could basically only win by massive levels of corruption. This ended up [[HeelFaceTurn turning Hitomi]] from the BigBad of the arc into one of the greatest heroes in the Empire's history, [[AssPull in a way many found dissatisfying]]. As a side bonus, she ended up becoming the Moon.
** The end of the Clan War was decided when the last two players in a tournament went to the tournament's storyline man and said that they wanted to team up to fight the Shadow instead of fighting each other. He promptly rolled with it.

* There are quite a few Franchise/{{LEGO}} set designers, PR workers and other staff who started out as prolific members of LEGO's large PeripheryDemographic. General consensus is that modern set design is for the most part ''much'' better for it, and it certainly contributes nicely to LEGO's extensive efforts to keep involved with the fandom and its events.

[[folder:Video Games]]
* ''VideoGame/{{Painkiller}}: Overdose'' was originally developed as a fanmade mod to the original game before the publishers of the original game, Dreamcatcher, decided to give the team funding to spin the mod into a full release to score a fast buck. The results show all too well.
* The notoriously [[SurrealHorror sur]][[SurrealHumor real]] ''Frachise/FiveNightsAtFreddys'' fangames ''Videogame/OneNightAtFlumptys'' and ''[[Videogame/OneNightAtFlumptys One Night at Flumpty's 2]]'' were originally supposed to be capped off with ''One Week at Flumpty's'', a GrandFinale third installment which got called due to a ''serious'' CreatorBreakdown stemming from the fact that {{Creator/Jonochrome}}, the guy behind the game who's also of Videogame/RiddleSchool fame, was afraid that the attention he got from these games would make people remember him more by his [[MagnumOpusDissonance fan game developer status than his game developer staus]], he even went as far as to briefly delete the two other games so no one could play them. However, as time passed and the initial shock went away, Jonochrome decided to provide the fans with the unfinished game, a ''carte blanche'' for them to do whatever they want with it, and an apology, saying that his behaviour was childish and that "no one gains anything from such a negative atitude". ''One Week at Flumpty's'' is currently being finised by a subreddit of fans that has since gained Jonochrome's full [[ApprovalOfGod support and approval]].
* [=NeverSoft=] were {{Big Name Fan}}s of the ''VideoGame/GuitarHero'' series prior to Creator/{{Harmonix}}'s departure. After Harmonix left, they took over the series and made a lot of [[TheyChangedItNowItSucks questionable changes]] to the series, including ''Guitar Hero III's'' infamous [[LuckBasedMission "Guitar Battles"]], FakeDifficulty, and market oversaturation of {{Mission Pack Sequel}}s that lead to [[FranchiseKiller the eventual death of the series]] [[GenreKiller (and plastic instrument video games in general)]].
* Tom Hulett and Simon Lai, the producers of ''[[VideoGame/{{Contra}} Contra 4]]'' for the Nintendo DS, both admit to being bigger fans of the earlier ''Contra'' games for the NES and SNES than the BossRush-filled later sequels like ''Hard Corps'' and ''Shattered Soldier'', making ''Contra 4'' as a homage to those early installments. Hulett in particular also admits to being a fan of the gag localizations of the early titles instead of the more direct and serious localizations of recent titles, which is why the manual of ''Contra 4'' is written in such a tongue-in-cheek tone similar to Konami's manuals during the NES era and which is why the two new main characters accompanying Bill and Lance are named Mad Dog and Scorpion, [[MythologyGag which were the nicknames given to Bill and Lance in the early American versions]]. However, they also retconned the events of ''Operation C'' from being a previous mission of Bill Rizer to being a previous of the "new characters" Mad Dog and Scorpion.
* This goes all the way back to VideoGame/{{DOOM}} - the "Final DOOM" mission pack, released by ID themselves, was two "fan" teams creating full episodes. Whether or not this qualifies as this trope or as AscendedFanboy depends on who you ask.
* The producer of ''VideoGame/TalesOfTheAbyss'' mentioned in a developer interview for the [[UpdatedRerelease 3DS version]] that the ''Tales'' teams now include fans who had played the early games, and that though their enthusiasm was good, their plot ideas often have to be gently vetoed.
* Seems to be the entire business model for Creator/TelltaleGames. Opinions vary, of course, but generally their work receives positive reviews from both critics and fans.
* The developers of ''VideoGame/XCOMEnemyUnknown'' were big fans of the original ''[[VideoGame/XCOMUFODefense X-COM]]'' and really wanted to do justice to the franchise. Strangely this was enforced too, allegedly any new comer to the team had to complete the original game before they could start work, leaving fans wondering [[NintendoHard how the game ever managed to be made.]]
* The ''VideoGame/SoulSeries'' had been run by creator Hiroaki Yatoriyama from the beginning all the way until ''Soulcalibur IV''. Then he stepped down as leader, and in his place were director Daishi Odashima and producer Hisaharu Tago. These two were the ones responsible for ''Soulcalibur V''. Many noted the [[TheyChangedItNowItSucks changes they made]], due to having a 17 year TimeSkip. This meant [[ReplacementScrappy replacing many of the veterans]] with blatantly {{anime}}-inspired characters, and a story that focused entirely on Patroklos Alexander, son of series veteran Sophitia, on his quest to save his sister Pyrrha. It's been pointed out that the whole story and characters feel very much like personal {{fan fiction}} being made into reality, instead of an actual sequel to ''Soulcalibur''. Even from a gameplay perspective, it borrowed many of its gameplay mechanics from ''Franchise/StreetFighter'' (and Daishi wasn't shy to admit being a fan of ''[[VideoGame/StreetFighterIII Third Strike]]''). Both of those men left, placing the series under the leadership of Masaki Hoshino. From his tenure came two poorly received FreeToPlay games, ''Lost Swords'' and ''Unbreakable Soul'', which were ultimately terminated from service. Many have pointed out that Hoshino's marketing is based on [[SexSells sex appeal]], something that was downplayed when Daishi was in charge, and has been compared to ''VideoGame/{{Dead or Alive}}''.
* ''VideoGame/CantrII'': The creator has largely left the game, leaving it to some staff to manage things. Over time, this has resulted in what has been referred to as the [[DrunkWithPower Internet]] [[ScrewTheRulesIMakeThem Illness]]. Basically, any [[{{GIFT}} normal person gets a chance to live out their powertrip fantasies, and go for broke]]. HilarityEnsues.

* ''Webcomic/{{Exiern}}'': The original creator and writer Drowemos first ''sold'' the comic to fan and author Dan Standing. As one of his first acts in charge, Standing invited fans to submit scripts to become the main writers.
* Deliberately invoked by Tycho of ''WebComic/PennyArcade'' with ''Legends Of The Hierarchs'' and ''Literature/SongOfTheSorcelator''. Tycho invited readers to flesh their wikis out with snippets of hilariously abominable prose.

[[folder:Web Original]]
* [[JustForFun/AvatarAndTheAirbendingFellowshipOfVampireSlayers Happens]] [[DarthWiki/ThePunishersSongOfEvangelionAndIMustScream repeatedly]] [[SugarWiki/MyLittleRainbowPrincessPrettyMoonShortcake on this]] [[Pantheon/{{Tales}} very]] wiki.
* Franchise/TheSlenderManMythos ''started'' smack dab under this trope. It helps that the Mythos has no real WordOfGod to hinge on except as it pertains to individual works, meaning followers are free to ignore and disregard works they think are doing a crummy job of it.
* As of 2015, the founders of the feminist geek website ''The Mary Sue'' have all moved on to other projects, and the site is now mostly run by newer contributors. Longtime members of the community have complained that the new management has steered the site towards social justice and away from geek culture.
* It's only been in small capacities, but the members of Creator/TeamFourStar have started to be included in actual ''Dragon Ball'' projects, like ''Xenoverse'' and ''Resurrection: F.''
* Parodied in [[WebVideo/UltraFastPony Ultra Fast Pony]], when a "writer strike" leads to the show having to resort to hiring a fan who said they would work for free, if they were allowed to be in an episode. Cue every negative FanFiction stereotype ever.

[[folder:Western Animation]]
* ''Franchise/{{Transformers}}'' has a lot of this, with many current writers and artists for the shows and comics being long-time fans. It's frequently cited as an example of this trope [[TropesAreNotBad done right]], as many feel that the franchise has been steadily increasing in quality.
** ''WesternAnimation/TransformersAnimated'' is what happens when these fans have a whole shiny new continuity-sandbox to play around in. The result is loads and loads of {{mythology gag}}s, the RuleOfCool reigning supreme, a kid-companion who ''doesn't suck'', [[TropesAreNotBad and a very, very happy audience]]. This was raised UpToEleven in the Japanese dub, where '''Music/JamProject''' sings the opening theme.
* ''WesternAnimation/TheSimpsons'' has suffered from this, with new generations of writers who were brought up on and inspired by the more surreal and extreme aspects of the show's humor focusing on that to the detriment of the characters. It seems a lot of the writers had different views of the characters, leading to skews in personality ''per episode''.
** It's fairly easy to trace when the show started to be truly run by people who were big fans when they were younger. Once they did, you began to see things like Homer having all the skin completely ripped off his torso, leaving his bones and organs visible, and shrugging it off and going about his business. Things like this made no sense for an episode of the show from early on... but it's ''exactly'' like something that would happen in a ''Treehouse of Horror'' episode, which have always been the most popular and often most rerun episodes of the show. So when fans took over, of course they wanted to write episodes in the style of their favorites ''all the time'' instead of waiting for once a year. This might also explain the increasing frequency of ThreeShorts WholePlotReference episodes.
** The first most notable instance of this happening was the hiring of Bill Oakley and Josh Weinstein. The duo were admitted fans of the series before joining the writing staff in Season 4. They stayed on, rising in the ranks and becoming showrunners for Seasons 7 and 8. Their "back to the family" approach saw a number of low-key, realistic episodes, and they were insistent on staying consistent with the characters (e.g. not making Homer completely stupid or a food monster).
* ''WesternAnimation/StarWarsTheCloneWars'' got a whole board of writers that were fans, and made it clear from all the references and overly long mythology gags they pack in the show. The most prominent example would be Dave Filoni's favourite character, Plo Koon, who is often mentioned on the SW websites and DVD extras. Other than the overuse of "I've got a bad feeling about this", there is no real difference now that the inmates have control except that [[RescuedFromTheScrappyHeap Anakin is likeable and Jar Jar doesn't automatically inspire homicidal rage]].
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' has a variation on this. Creator/LaurenFaust, the main creative force for the show, had a habit of playing with MLP figures when she was a kid and making up her own personalities for them (although those personalities were usually at least to a certain degree based on the characters' canonical ones). Said personalities became the basis for the main cast of her show. [[TropesAreNotBad This wasn't a bad thing]], since she took a franchise whose previous animated adaptations were mostly considered [[MerchandiseDriven lazy toy commercials]] and made a show with interesting characters, good writing, and nice animation.
* ''WesternAnimation/{{Ben 10 Omniverse}}'' makes use of this, as [[RecycledScript there are many scripts identical to previous episodes of other iterations]], [[CanonDiscontinuity blatantly ignoring some of the most oft-criticized aspects of the previous sequels]] (or in some cases, ones that [[BrokenBase break the base]]), and bringing Ben uncomfortably close to his first series incarnation while ignoring the maturing of the previous sequels. The character designs are also much closer to the first series. [[LoveItOrHateIt Whether or not you're fine with these is up to personal taste.]]

[[folder:Theme Parks]]
* Disney's ''Ride/TheHauntedMansion'' has one of the most split-apart BrokenBase you could find, with (literally) thousands of conflicting {{Fanon}}s constantly debated on the Internet. The SLG comics (which created backstories for the characters, partly based on fanmade backstories and obviously written by fans of the ride rather than Imagineers) had to be retconned out of continuity to cool the angry fans who had different fanons down. Most recently, an extended, wackier graveyard was added to the queue. It contains numerous retcons and tributes to DeletedScenes, characters and concepts, and several nods to obscure elements of the fandom.

[[folder:Real Life]]
* [[WrittenByTheWinners To the victor go the history book deals]].
* Every classical historian writing after Thucydides is essentially a promoted fanboy of his who has control over what we know about their world.
* Just about all we know of the philosopher Creator/{{Socrates}} is through the writing of his fanboy, Creator/{{Plato}}. There has been much argument as to how much is really Socrates, and how much was Plato using his dead hero as a mouthpiece. Diogenes of Sinope had some scathing opinions on the subject.
