->'' Oceania was at war with Eurasia: therefore Oceania had always been at war with Eurasia."''
-->-- ''Literature/NineteenEightyFour''

A sort of {{Retcon}} achieved not by putting out sequels that change the official story, but by actually going back and changing it in the original work, so that subsequent printings of "the same" work are actually different.

May happen as the result of deciding after that fact that something was UnfortunateImplications, DudeNotFunny, or TooSoon. But could also be caused by FlipFlopOfGod, ScienceMarchesOn, or being ScrewedByTheLawyers. So like many tropes, this can be [[TropesAreNotBad for good]] or [[TropesAreNotGood for evil]].

Prime source of AdaptationDisplacement for more [[FleetingDemographicRule recent fans]]. May lead to a LimitedSpecialDirectorsUltimateEdition and/or GeorgeLucasAlteredVersion. Possibly may lead to a BrokenBase. See also CreatorBacklash, especially if the original version is taken off the shelves.

Named, of course, after Creator/GeorgeOrwell, specifically ''Literature/NineteenEightyFour'', where the main character's job at the Ministry of Truth is to rewrite old newspaper articles to hide the government's flip-flopping on political issues.

Often happens in a GeorgeLucasAlteredVersion.

Contrast DeathOfTheAuthor, CanonDiscontinuity. Related to EarlyBirdCameo, where an adaptation or remake of a work puts in extra early {{Foreshadowing}} for later plot developments. Not to be confused with OrwellianEditor. Compare FlashbackWithTheOtherDarrin.

[[folder:Anime and Manga]]
* ''Manga/LuckyStar'' has a minor example: Konata was originally portrayed as a cool GamerChick, but was soon [[CharacterizationMarchesOn changed]] into an down-to-earth, sort-of-[[LovableSexManiac pervy]] OtakuSurrogate. When the {{yonkoma}} were collected into volumes, Yoshimizu changed Konata's lines in some very early strips to make her image consistent. Because this change was very early on in the series and [[WordOfGod Yoshimizu discussed that]] in the [[BonusMaterial omake]], it is not as displeasing. Parodied in a later omake, which consists of several "What if"-strips. One of them is "What if episode 1 was drawn today", which is simply a reprint of the strip just as it was published in the first volume.
* The original dubbed airing of the Dungeon Dice Monsters mini-arc of the ''Anime/YuGiOh'' anime used the original designs for the Dice Crests. For no adequately explained reason[[note]] but possibly for the same reason that the card images are altered for the dub[[/note]], all subsequent airings used ConspicuousCG dice with a completely changed set of Crest markings. Fortunately, the American board game version and its UsefulNotes/GameBoyAdvance adaptation used mostly the original designs, with only the Magic Crest changed to a circle with a lightning bolt in the center.
** The original ''Weekly Shonen Jump'' printing of a chapter in the ''Manga/YuGiOh'' manga, of Yugi's duel with Bakura, had Bakura's trump card monster called "Dark '''Necrophilia'''". This was then changed to "Dark Necrofear" for the following chapter and the graphic novel reprints, to avoid the UnfortunateImplications of the original name.
* Franchise/{{Pokemon}}:
** ''Manga/PokemonAdventures'' gets a ''lot'' of changes and revisions when its chapters get collected into tankobon form. Makes sense, as the manga gets serialized in three different magazines and out of order to boot, not to mention the mangaka often adds new details to incorporate whatever new features that had since been released from the new games.
** While the original design for the Pokémon Jynx has been a subject of controversy for years (see Video Games section below), The Pokémon Company International has taken action by pulling three episodes that feature Jynx in her original design in the same manner that The Pokémon Company in Japan pulled "Cyber Soldier Porygon", i.e. they pretend that these episodes never existed. What makes this worse in Jynx's case is that one of the episodes just features her in a ''small cameo'', and that one of the pulled episodes was remastered in Japan so that Jynx would appear in her current design.
* A minor one in Creator/VizMedia's English edition of the ''OnePiece'' manga involves a particular character being called "Zoro" in early printings of the first few volumes, [[SpellMyNameWithAnS later being changed to "Zolo"]] to match Creator/FourKidsEntertainment's dub of the TV series. However, Zolo stuck for Viz even when Creator/FUNimation later changed his name back to Zoro in their own dub.
** Done in reprints of the volumes to Whitebeard's flag as the Swastika (the Nazi symbol) was off limits to use.
* The Japanese home video release of the 1986 ''Anime/FistOfTheNorthStar'' theatrical movie changed the ending of the final battle so that Kenshiro's final battle with Raoh ends in a stalemate rather than losing like in the original theatrical version. Even though the theatrical ending was used for all the international releases, it didn't get to be featured in any of the Japanese home video releases until the DVD release in 2008 and even then it was only available as a bonus feature in first-print editions of the DVD.
* In the anime adaptation of ''VideoGame/ArtOfFighting'', Yuri Sakazaki was originally voiced by a young, [[RetroactiveRecognition not-yet-famous]] Music/AyumiHamasaki, who also appeared in a series of live-action promos for ''Art of Fighting 2'' in Japan. When the anime was re-released on DVD in Japan, all of Ayumi's dialogue were dubbed over by Kaori Horie, Yuri's actual voice actress in the games, since Hamasaki (who had become a huge JPop star in the intervening years) wanted a great share of the royalties for the use of her voice.
* Along with more standard panel redraws, a few instances occur in the 2003 UpdatedRerelease of the ''Manga/SailorMoon'' manga, (published stateside by Kodansha in 2011), some of which carry over to ''Anime/SailorMoonCrystal.''
** During Act 2's Crystal Seminar story (which introduced Ami), an instance of a floppy disk from the original 1992 version was replaced by a CD-ROM in the re-released version. Also, to be consistant with the [[Series/PrettyGuardianSailorMoon tokusatsu version]] that was airing at the time, the "sailor senshi" are referred to as "guardians".
** An unnamed [[FogOfDoom fog attack]] in the manga (referred to as "Sabao Spray" in the [[Anime/SailorMoon first anime]]) was changed to be called "Mercury Aqua Mist", to tie in with the live-action version. Sailor Moon's first sceptre was also redrawn to have a crystalline top.
** Sailor Jupiter had a flower-themed belt added to her first uniform in redrawn panels, a detail that Takeuchi had originally wanted to include on her but had never gotten the chance to.
** The 2011 English-language editions from Kodansha USA underwent some minor revisions in reprints to correct some mistakes, including an instance of mistranslating Jupiter's "Sparkling Wide Pressure" as "Spark Ring Wide Pressure," and Queen Beryl referring to herself as "''Princess'' Beryl."
* In ''Manga/DeathNote'', Near was introduced as a serious character, but had some childish expressions in certain early chapters. When these chapters were collected into the tankobon editions, Takeshi Obata redrew the panels so Near's face would be less expressive.
** Another example involved [[spoiler: the death of Light's father]]. In the original Jump serialization, Ryuk speculates that since [[spoiler: Soichiro never used a Death Note, he would go to Heaven]]. As the final chapter of the manga ultimately revealed that [[spoiler: there is NO heaven or hell (at least, Ryuk doesn't think so), Ohba altered the line in the tankoban release to prevent any further misunderstandings, with Ryuk now speculating that Mr. Yagami would have died peacefully]].
* A necessary one happens in ''Anime/QueensBlade Rebellion'' between the web version of the Illustrated Stories and the paperback version: In the Net-based one, Mirim kills one of the Tomoe's fellow shrine maidens (later revealed to be named Tokiwa) when trying to help Annelotte escape from Gainos. Since that scene is out of character for her, in the paperback version, Tokiwa was killed by random guards instead, while Mirim is chasing Annelotte instead. This was omitted in the animated version, as the aforementioned scene never happens and the events are developed in a different direction. Also, the manga version has [[spoiler:Leina using her "Maria" persona]] rescuing Annelotte instead, rather than Tokiwa, and Mirim does not appear until some chapters later.
* The early print run of ''Manga/{{Cyborg009}}'' in Weekly Shonen King had the lead hero's name first given as "Joe Muramatsu", which later changed to "Joe Shimamura". Ishinomori would revise the earlier chapters when they were reprinted, to correct that continuity error. He also corrected a few instances where 003's surname was used in light of her given name, or where he'd used the wrong katakana for 003's given name and called her "Francois" instead of "Francoise".
** The chapter "The Aurora Strategy" originally had a character named "Dr.Dolphin" and his daughter "Iruka". In some reprintings, Iruka's name was modified to "Cynthia", which the 2001 anime used.
* One of these happened in ''Manga/YuruYuri''; early in the manga, Akane was originally Akari's (unnamed) older brother. He was converted into a girl for the anime, and this change persisted into later chapters.
* When ''Manga/JoJosBizarreAdventure: Stone Ocean'' was still running in Shonen Jump, [[spoiler:the final evolution of Pucci]]'s Stand was called [[spoiler:[[Music/LedZeppelin Stairway to Heaven]]]]. When it was collected in tankobon, it was renamed [[spoiler:[[Music/{{Queen}} Made in Heaven]]]], possibly because the lyrics fit the motives of its user better. Fan translations are more likely to call it the latter.
* When Creator/FUNimation reissued ''Anime/DragonBallZ'' in remastered DVD season sets in 2007, they re-recorded parts of their own dub. Since the first 67 episodes weren't recorded until 2005, the remaining episodes (recorded from 1999-2003) had some inconsistencies, especially in the Ginyu/Frieza episodes, where over half of the characters had redubbed dialogue. Some characters (Vegeta, Krillin, Frieza) had the same actors giving much improved performances, while others (Ginyu, Burter, Tien) had been recast, and were now being redubbed by their replacement actors for consistency. Most of this redubbing stopped by the Android saga, though notably Maron, Spice, and Mustard were redubbed in the Garlic Jr. episodes by new actors. To hear the dub as it originally sounded, you'd need to [[KeepCirculatingTheTapes track down the original DVD singles]].
** They did something similar when ''Manga/YuYuHakusho'' was released to Blu-ray, though it was only small changes, and far less noticeable ones.

* ''Franchise/ArchieComics'' loves to reprint their older stories in their newest issues. You'd be hard-pressed to find even one of these reprints that hasn't had a good portion of the dialogue rewritten or panels redrawn in order to avoid sexism, racism, UnfortunateImplications, to give a dark story a happier ending, or even to change a walkman into an iPod, or alter a fourth-wall breaking line to remove a reference to Dan [=DeCarlo=].
* ''ComicBook/XMen Classic'' was a reprint comic of the early adventures of the "All-New" team. Some of the reprints were edited to conform with more recent interpretations of the character. E.g., when Nightcrawler was visiting Banshee's ancestral castle, his ability to (explicitly) turn invisible in darkness was edited so that he's merely very hard to see (i.e., you can no longer see the background through his body).
* The characters in ''Aliens'' were renamed, and the stories retitled, when ''Alien 3'' made them inconsistent with the movie series.
* The ComicBook/ArchieComicsSonicTheHedgehog special issue ''Sonic Firsts'' reprinted a few old stories, with Princess Sally recolored to look more like her modern design and all references to "Boomer" replaced with "Rotor" (whose name was changed early on to match the [[WesternAnimation/SonicSatAM animated series]]).
** All of the compilations also recolor Sonic's eyelids from tan to blue, along with various art improvements and continuity corrections.
** In the case of "Boomer", though, they actually do acknowledge it later on, by claiming that Boomer was a nickname he was given by his parents and Rotor is his real name (it becomes a minor plot point when Silver, [[LeaningOnTheFourthWall who is from the future and thus reading about old events, realizes that references to Boomer stopped early and Rotor came in at the same time]] - and mistaking that for meaning Rotor was a spy.)
* Creator/DCComics has done this a few times in the past.
** For example, in ComicBook/{{Supergirl}}'s first story with the Comicbook/{{Legion Of Super-Heroes}}, the following dialogue occurred when Supergirl figures out that the Legion who wants to induct her into their club is the same one that inducted ComicBook/{{Superboy}}.
--->'''Original printing (from ComicBook/ActionComics #267):'''
-->'''Lightning Lad:''' Not the same ones he knew, although we have the same names...\\
'''Saturn Girl:''' We are the ''children'' of the three young super-heroes who befriended ''Superboy!'' We are [[LegacyCharacter carrying on the]] ''[[LegacyCharacter Legion's]]'' [[LegacyCharacter traditions]]...
--->'''Reprint (from Action Comics #334):'''
-->'''Lightning Lad:''' You're hitting on all cylinders, ''Supergirl!''\\
'''Saturn Girl:''' We've admired ''Superboy''...and you! That's why we made this trip!
** A second example concerns Jonathan and Martha Kent. In Franchise/{{Superman}} #161, a story was printed where they go to a remote island and accidentally unleash an incurable centuries-old virus on themselves, explaining how they died. However, when the story was reprinted in Superboy #165, they were drawn significantly younger. This is because twenty issues prior, a story with a TrumanShowPlot was printed where the producer, concerned with his viewers not accepting an old couple with a teenage son, made the senior citizens of Smallville younger, Pa and Ma Kent among them.
** In the sixties, there was an attempt to establish a 30th century Superman, whose adventures were published in ''Superman'' #181, ''Action Comics'' #338-339, and ''World's Finest Comics'' #166. However, there was no effort to tie in the ''Legion of Super-Heroes'' series (which supposedly took place in the same time frame), so when his first three stories were reprinted, the setting was retconned into the 25th century.
** In "Superman Under the Red Sun" from ''ComicBook/ActionComics'' #300, when Superman manages to make it back to the Fortress of Solitude and finds a tiny rocket left from the enlarged [[CityInABottle Kandor]], Superman gets some lead-wrapped Red Kryptonite with the intention to use it on himself, but a few panels later he ends up using a still functioning ShrinkRay instead. After using the rocket to return to the present, he goes on to say he'll wait until the Red Kryptonite's effect wears off, suggesting he had used the Red-K to shrink himself in the first place. Of course, when the story is reprinted more than a decade later, the panel depicting Superman shrinking himself with the shrink ray was changed so that he's using the Red Kryptonite instead.
* The original print of ''[[ComicBook/TheNightGwenStacyDied The Amazing Spider-Man #121]]'' shows a "snap" sound effect when Spider-Man catches Gwen Stacy with his webbing while falling, implying that the sudden whiplash caused her neck to break, thus killing her. Reprints of the issue in trade collections omitted the "snap" effect, leaving the cause of her death ambiguous.
* Thanks to legal issues, all reprints and collected editions of the Comicbook/MarvelNOW ''Comicbook/TheAvengers'' relaunch have changed Smasher's real name from "Izzy Dare" to "Izzy Kane". Her last name was originally supposed to be a hint that she was the granddaughter of ComicStrip/DanDare, but [[WritingAroundTrademarks was instead changed]] to make her the granddaughter of an obscure Golden Age hero named Captain Terror.
* Taken UpToEleven in ''Marvel Tales #159''; in the "Marvel Mails" section, someone named Vincent Gonzalez wrote in, asking the editors to go all the way in terms of changing the reprinted Spider-Man stories. We then see a sequence from the story "Spidey Strikes Back" (originally printed in ''The Amazing Spider-Man #19'') with the changes in effect. WereStillRelevantDammit (and {{hilarity|Ensues}}) ensues. [[http://assistanteditorsmonth.blogspot.com/2011/06/marvel-tales-159.html You can find it here.]]
* In the original printing of ''ComicBook/InfiniteCrisis'', ComicBook/{{Superboy}} challenges Superboy-Prime with the line: "Come on, you motherf-!". Due to complaints over the implied language, this was truncated to a simple "Come on!" in reprints and the trade paperback.
* The {{Brainwashed}} ComicBook/{{Batwoman}} in ''ComicBook/FinalCrisis'' initially had a [[BoundAndGagged ball-gag]] in her mouth as part of her DarkerAndEdgier [[BondageIsBad design]], but this was removed from subsequent reprints and collected editions. A few other changes were made as well, such as correcting some coloring mistakes on characters like [[ComicBook/NewGods Shilo Norman]].
* Averted for ''ComicBook/UsagiYojimbo''. Stan Sakai has stated that he regrets presenting the BigBad Lord Hijiki in one of the earliest issues as the only human being in a world full of talking animals (his face has never again been seen on panel since then), but admits that the first collection has gone through so many printings that going back and changing it now would be pointless.
* When Marvel began reprinting old horror and sci-fi tales in the 70s, they sometimes altered details to make the stories better fit the then-current Franchise/MarvelUniverse continuity. For instance, a reprint of a 60s ''Strange Tales'' story had a generic scientist {{Retcon}}ned into being a young [[ComicBook/AntMan Hank Pym]], while a reprint of a 50s ''Menace'' issue had a nondescript foreign spy changed to an agent of Comicbook/{{Hydra}}.
* A plot point in ''LightNovel/DirtyPair: Dangerous Acquaintances'' involved Kei and Yuri [[MuggedForDisguise mugging a pair of hostesses]] and stealing their PlayboyBunny uniforms. Due to possible copyright issues with Playboy, the art was altered in the trade paperback to remove the ears and tails from Kei and Yuri's costumes.
* Some of the more recent releases of [[UsefulNotes/TheGoldenAgeOfComicBooks Golden Age]] Creator/DCComics titles have been altered to remove content that would be deemed offensive today. For example, certain editions of ''ComicBook/WonderWoman'' were edited to remove offensive caricatures of African-American and Japanese characters.
* The collected editions of the ComicBook/{{New 52}} ''Comicbook/TeenTitans'' volume got hit with a few of these:
** All references to Tim Drake having been [[Comicbook/RobinSeries Robin]] were removed. Interestingly, DC left in the picture of him wearing his Robin outfit (it has an "R" as the logo, not the bird head logo that Red Robin uses - the [[EpisodeZeroTheBeginning zero issue]] would confirm that he wore that costume, but "always" called himself Red Robin).
** A cameo from Miss Martian (wearing her ''WesternAnimation/YoungJustice'' [[{{Retcanon}} costume]]) was removed and replaced with an image of a generic, unnamed teen heroine.
** A line in ''ComicBook/{{Batwoman}}'' that had Flamebird referencing her past as a Titan and a battle with Comicbook/{{Deathstroke}} was also edited out in the collected edition.
* Some dialogue from ''{{ComicBook/Batgirl|2011}} #37'' was changed for the TPB collection to remove the implication that Barbara Gordon was shocked and disgusted to discover that an apparently female villain was a cross-dressing man, which had been seen by readers as out-of-character and transphobic.
* The original printing of ''We Can Never Go Home'' #3 had a CostumeTestMontage where Maddie was seen dressed as trademarked heroines like Franchise/WonderWoman, Comicbook/{{Supergirl}}, ComicBook/MsMarvel, ComicBook/PowerGirl, ComicBook/{{Zatanna}}, [[Comicbook/{{Watchmen}} Silk Spectre]], [[Comicbook/JudgeDredd Judge Anderson]], Comicbook/TankGirl and [[Comicbook/TheSandman Death]]. A number of the outfits had to be omitted in the trade paperback, but were replaced with the costumes of ''other'' recognizable characters, like ComicBook/{{Storm}}, ComicBook/{{Psylocke}}, ComicBook/{{Robin}}, ComicBook/{{Batgirl}}, and ComicBook/TheMightyThor.
* The ''Magazine/DoctorWhoMagazine'' story "The Crystal Throne" had dialogue changes in the collected edition to a scene where Strax encounters a Sikh man. The initial comedy dialogue, intended to be Strax being InnocentlyInsensitive, apparently came across as too similar to racist humour that Sikh readers had experienced being directed at them in real life.
* The first ''X-Men: X-Tinction Agenda'' collection removes two pages, adding two new pages to eliminate mentioning a subplot. Fixed in the later hardcover edition.
* The original version of ''ComicBook/TheKillingJoke'' uses the "new look" Batman costume with the yellow oval behind the bat insignia, which Batman was still wearing in the main comics in 1988. When ''The Killing Joke'' was digitally recolored in 2008, the yellow oval was [[http://comicsalliance.com/files/2010/09/batmanbolland.jpg removed]] from every single panel, leaving just the bat, because in 2008 Batman no longer had the oval. This change is baffling since no other attempts were made to modernize the story, which is still canonically set when Batman still had the oval.
* A miscommunication in ''Comicbook/DetectiveComicsRebirth'' led to a scene showing a Christian cross on the tombstone of Comicbook/{{Batwoman}}'s mother, even though she and her family are Jewish. The digital and collected editions edited out the cross and replaced it with a Star of David.
** Another miscommunication led to [[spoiler:Ra's al Ghul]] being revealed as the mystery villain in ''All-Star Batman''. Collected editions edited it out.

[[folder:Fan Works]]
* This trope is par for the course in fanfiction, with ''many'' authors revising early chapters of their fics, either to improve the writing quality or to fix inconsistencies.
* When Durandall wanted to {{retcon}} something in ''FanFic/KyonBigDamnHero'', it was easiest for him just to go back and change the chapters themselves. Usually, this only applied to character names.
* In chapter 7 of [[FanFic/TheLongingverse The Last Crystal Unicorn]], Shimmering Ruby insults Shining Armor, calling him "retarded" behind his back. This was found to be offensive by many, so the insult was changed to "pitiful".
* A minor example from ''Fanfic/MassEffectInterregnum''. When the game's ''Lair of the Shadow Broker'' DLC was released, it included a list of Garrus's squadmates. Several of them had been included in the fic with original names, so the characters in question were renamed to match.
* In ''FanFic/SylviaTheSylveon'', Moondancer's nickname was Moonie, which was meant to be a reference to early 90s ''Manga/SailorMoon'' fans. But after the UnfortunateImplications were pointed out, the author changed it to Dancer.
* In ''FanFic/FutariWaPrettyCureBlueMoon'', some characters had brown or black hair, but the author decided there was too many brown and black haired characters, so their hair colors were changed to more wild ones, the most notable being the now green haired [[AlphaBitch Emiru.]]
* ''Fanfic/RedFireRedPlanet'' had the author discover he'd made a mistake with an Andorian minor character, giving him the wrong [[http://memory-beta.wikia.com/wiki/Andorian_genders Andorian gender honorifics]]. "Sh'" is a female-analogue prefix, but the Andorian in question was male, so Tropers/StarSword just went back through the first three chapters and batch-replaced every instance of "sh'Kreem" with "ch'Kreem".
* Creator/NimbusLlewelyn occasionally does in ''Fanfic/ChildOfTheStorm''. The changes are usually minor, and made after someone points out a mistake. This is not always the case, however - once he added over 4,000 words to a chapter in the form of an extra scene or two.
* ''Fanfic/SoulEaterTroubledSouls'': CD/Grade, the author, constantly goes back to edit, readjust, and add little bits of information to the story.
* ''FanFic/AChanceMeetingOfTwoMoons'': In the fall of 2017, Evilhumour and Anon e Mouse Jr. went back and revised the earlier chapters, primarily to fix spelling and grammar, but also making a few other modifications. Among them included adding an earlier mention of the Doors to the Realms In Between (one had already existed later in the story), and changing one of Elusive's lines into a BigYes.
* ''Fanfic/DavionAndDavionDeceased'' originally had the family of Commodore Grec escape the Amaris Coup as they were invited to New Avalon. The author later wrote Grec as bereaved by the Coup, amending the previous reference to indicate that he declined to invite his family as it was a privilege other soldiers couldn't share, something that more than justified his later emotional distress.

[[folder:Films -- Animated]]
* Several movies from Franchise/DisneyAnimatedCanon have had this done to them:
** In one scene in the original [[UsefulNotes/{{VCR}} VHS]] and UsefulNotes/LaserDisc releases of ''Disney/TheLionKing'', a dust cloud kicked up by Simba seems to form the word "SEX." Although the animators claimed that it actually said "SFX" (special effects), the scene still got edited in later editions.
** ''Disney/{{Aladdin}}'':
*** The opening song describes [[ArabianNightsDays Agrabah]] as a "barbaric" locale "where they cut off your ear if they don't like your face." In response to complaints about the UnfortunateImplications of that line, later editions replaced it with "where it's flat and immense and the heat is intense" (though you can still find the original lyrics in some foreign dubs).
*** At one point in the movie, Aladdin gets attacked by the [[PantheraAwesome tiger]] Rajah and says, "Come on...good kitty, take off and go...". Due to other, simultaneous noises (possibly Rajah snarling), it's hard to understand what he says, and some people said it sounded like "Good teenagers, take off your clothes." The line was later cut out in the DVD release.
** ''Disney/{{Fantasia}}'': In one scene in the original film, several young black centaurettes with donkey bodies (the one with the most screentime was nicknamed Sunflower) are seen performing menial duties for the beautiful Aryan centaurettes and for Bacchus. Needless to say, later audiences considered this unacceptable, and Sunflower and friends have mysteriously disappeared from all releases after 1969. The two lighter-skinned zebra centaurettes who attend Bacchus got some of their scenes trimmed as well, including a scene where one is trying to help the very drunk Bacchus down from a gazebo. Recent versions have also clipped a few seconds from the ''Night On Bald Mountain'' segment because of brief views of nude demons. Furthermore, Disney has cracked down on videos on the Internet showing footage of the unedited scenes, so good luck finding any evidence of the original version.
* The theatrical release of ''WesternAnimation/HotelTransylvania2'' contained a joke spoken by Kakie the Cake Monster, "the scariest monster of all is diabetes!" However, parents and groups reacted quite negatively about the line's implications, so Sony Pictures quietly replaced the line with laughter by Kakie for all future releases of the film.

[[folder:Films -- Live-Action]]
* The ''Franchise/StarWars'' Special Editions included, along with updated special effects, various edits to connect it to the prequel trilogy. Then there was [[TheDogShotFirst Greedo firing at Han Solo]], which may have been done to maintain the film's PG rating[[note]]The PG-13 rating didn't exist during the making of the Original Trilogy.[[/note]]. Later reissues further changed it to them [[TakeAThirdOption both going for their weapons at the same time]], [[{{Wiki/Wikipedia}} The Other Wiki]] has a [[http://en.wikipedia.org/wiki/List_of_changes_in_Star_Wars_re-releases full article about the changes]].
** This is not the first Orwellian Retcon in the franchise. When the first film was released in 1977, the opening crawl did not contain "Episode IV - A New Hope". After it became a runaway success, it was re-released to cinemas with this added, and thus began Lucas' claim that there had always been a nine-movie plan.
* Director Creator/MichaelMann suppressed copies of the original theatrical cut of ''Film/LastOfTheMohicans'' after some fans expressed displeasure at removal of scenes and music from the [[LimitedSpecialCollectorsUltimateEdition director's cut]] which Mann decided he didn't like ten years later. Various character-driven scenes were excised and action scenes added; complicating things, choice bits of dialogue were edited in, but the overall length of the film didn't change due to the volume of cuts. Altered sound design consisted of recycled bits of soundtrack, with the volume turned down. To this day, the theatrical cut is [[NoExportForYou only available in Europe]].
* The original showings of ''Film/StarTrekTheMotionPicture'' had dialogue describing the VGER cloud as being "Over 82 A.U.s in diameter." Subsequent prints and the DVD release edited the dialogue slightly so now it is described as being "Over 2 A.U.s in diameter," which better fits with the established canon for how fast the Enterprise travels under impulse power over the timeframe of the movie. (Earlier video releases, such as the widescreen UsefulNotes/LaserDisc of the theatrical cut and the 4:3 extended TV cut, do retain the 82.)
* The phone number in ''Film/BruceAlmighty'' was not originally an example of the FiveFiveFive trope; Creator/{{Universal}} digitally altered all releases after the original theatrical print because the original number turned out to actually belong to people in various area codes. Even more confusingly, although the English audio track was overdubbed to match the new number, the French dub on the UsefulNotes/{{DVD}} ''wasn't'', no doubt leaving many Francophones confused as to why the number on screen didn't match the one read out by Bruce.
* The extended edition film of ''Film/TheLordOfTheRings: The Return of the King'' changed the time of day for Pippin finding Merry on Pelennor Fields from the theatre version to the DVD version, showing that Pippin had been searching for Merry for several hours rather than the few minutes implied by the theatrical version. Note that both editions have always been available on DVD.
** The commentary track reveals that the time of day in this scene depended on whether the Houses of Healing scene was included or not, since Merry doesn't appear in it.[[note]]In the book he is in that scene, though.[[/note]] And indeed, it was cut from the theatrical version but restored in the extended edition.
* In the original release of ''Film/{{Traffic}}'', the drug czar's daughter, a teenage drug addict, attends Cincinnati Country Day School, a private prep school in the Cincinnati, Ohio area. Amid [[http://news.bbc.co.uk/2/hi/entertainment/1112349.stm protests from school administrators who objected to the association of the school with drug use]], the reference to the school was scrubbed from the DVD release and TV broadcasts.
* Original releases of ''Film/TheCrush'' have the teenage StalkerWithACrush named Darien, after a real woman the writer knew. When the real woman sued him and won, subsequent releases dubbed in the name Adrienne, with varying degrees of success.
* The original English version of ''Film/GodzillaVsMechagodzillaII'' was bumped up to stereo and had most of its dialogue re-dubbed by different actors when it was finally brought to the United States in 1999 by Creator/TriStarPictures for unknown reasons. The only evidence of the original version is a Hindi theatrical print made without a clean music and effects track, so English dialogue is sometimes heard unscathed. So far, no full length release of the original dub is known to exist.

* In 1831, Mary Shelley rewrote significant portions of her 1818 novel ''Literature/{{Frankenstein}}'', resulting in a much more fatalistic text.
* ''Literature/EndersGame'' originally had the main character use the N-word, and depicted Russia in a different light (it was written during the UsefulNotes/ColdWar). Before Orson released an edited version, he told all of his fans that if they sent their copies of ''Ender's Game'' to him, he'd send them back free copies of another, not yet released, book of his. What did Orson do with the copies he received? [[OldShame Destroyed them.]]
* When ''Literature/TheLordOfTheRings'' came out, ''Literature/TheHobbit'' was changed to agree with it about how Bilbo got the ring from Gollum. This was touched on cleverly in the text. It was implied that the version recorded in the first edition of ''Literature/TheHobbit'' was the same as the false account that Bilbo [[LiteraryAgentHypothesis told the Dwarves and recorded in his book]]. Bilbo later confessed the truth to Gandalf, then Frodo learned of this from Gandalf [[RecursiveFiction and edited his uncle's book]]. Thus, the idea of Bilbo lying being out-of-character isn't dodged but made meaningful, since Gandalf found the idea of anyone giving up the ring to be very suspicious.
** Also happened with some Elvish sentences in ''The Lord of the Rings'' itself. Some of these changes might be seen as typos that went unnoticed in the first edition, but some were clear changes.
* Creator/EdmondHamilton's book ''Literature/TheStarKings''. In the original ending, the hero returned to his own time and body, and his love followed him some time later by swapping bodies with an incurably comatose girl. Once Hamilton wrote the sequel, that changed to her contacting him telepathically and saying they are working on a way to transport him into her time physically. For some reason, however, some recent printings still include the original ending.
* Creator/PhilipKDick's novel ''Literature/DoAndroidsDreamOfElectricSheep'' was originally set in 1992. After TheFilmOfTheBook ''Film/BladeRunner'' was released, subsequent printings changed the year to 2019.
* Creator/ArthurCClarke:
** Clarke rewrote the first chapter of ''Literature/ChildhoodsEnd'' to avoid TheGreatPoliticsMessup. However, he does also include the original first chapter in some editions.
** In-Verse example: In ''Ghost From The Grand Banks'', one of the main characters made his fortune performing Orwellian Retcons on old classic movies, digitally erasing the EverybodySmokes trope by replacing such films' omnipresent cigarettes and pipes with lollipops, chewed pencils, etc.
* Creator/RASalvatore changed some details of Drizzt's backstory in later drafts of ''Literature/TheIcewindDaleTrilogy'' so as to better fit his expanded conception of the character's origins in ''Literature/TheDarkElfTrilogy''. Specifically, the line "Two hundred years of living many miles below ground had not been erased by five years on the sunlit surface. To this day, sunlight drained and dizzied him." The prequel trilogy's timeline established that Drizzt was only in his mid-forties or so.
* The chronologically last book of the Literature/EnchantedForestChronicles, ''Talking to Dragons'', was written first. When it was republished, some minor changes were made to make it agree with the other books.
* Happens a lot in reprints of Creator/EnidBlyton stories, partly to change money references to decimal currency but also covering minor plot points (one novel has the characters bribing a girl with chocolate, rather than money as in the original). However, a scene in ''Secret Seven Fireworks'' where the Seven accidentally set fire to the shed where they've stored their fireworks and set them all off was rewritten to have the shed instead containing their guy (presumably because that was considered less dangerous), meaning they acquire a new guy by the next chapter and the original ending of the police giving them new fireworks as a thank you was lost. (The novel also alters all references to them buying fireworks to their parents buying them for them, to cover modern age restrictions on sales.)
* Creator/StephenKing rewrote and expanded large portions of [[Literature/TheGunslinger the first volume]] of ''Franchise/TheDarkTower'' to "better fit in" with the later books. This included {{retcon}}ning all of the villains from Roland's past as the [[ItsASmallWorldAfterAll same guy]]. Since ''Literature/TheGunslinger'' as originally written is composed in a style unlike King's later works, and features {{call back}}s to story elements that were [[ContinuityLockOut never expanded on]] in the finished work.
* King's ''Literature/TheStand'' was originally set in 1980. Subsequent printings were set in 1985, then the uncut version in the 1990s (with references to AIDS and a few other cultural changes).
* In one of the more famous examples in literature, at least among Trekkers, Della van Hise's ''Series/StarTrekTheOriginalSeries'' novel ''Killing Time'' was released and then almost immediately recalled when it was discovered that the author was a former K/S SlashFic writer, and that this comes through blatantly in the original text of the novel[[note]]no, the originally published manuscript wasn't ''explicitly'' K/S, but the subtext was considerably heavier[[/note]]. The next edition had the worst of the subtext edited out, but original copies can still be found on eBay and in used bookstores, and many K/S fans actively hunt them out.
* Small-scale example: Any reprint of the early ''[[Literature/InheritanceCycle Eragon]]'' books now marks them as the Inheritance Cycle [[TrilogyCreep instead of the]] Inheritance Trilogy.[[note]]Which has the added benefit of [[SimilarlyNamedWorks avoiding confusion]] with [[Literature/InheritanceTrilogy another book series]].[[/note]]
* The previous publisher of ''Literature/AvalonWebOfMagic'' went bankrupt. In the switch to Creator/SevenSeasEntertainment, the author revised the books to avoid plot holes and ridiculous behavior.
* The original Oompa-Loompas of ''Literature/CharlieAndTheChocolateFactory'' were black, and specifically mentioned to be from DarkestAfrica. After numerous people pointed out the UnfortunateImplications of Willy Wonka as a slave owner, later printings changed them to the white and somewhat hippie-ish inhabitants of Loompaland. Additionally, the character of Veruca Salt was originally known as Veruca Cruz.
* ''Literature/HarryPotter'':
** Later editions of ''Literature/HarryPotterAndThePhilosophersStone'' were edited to make Nearly Headless Nick's claimed age match with the age given for him in ''[[Literature/HarryPotterAndTheChamberOfSecrets Chamber of Secrets]]''. Also in ''Philosopher's Stone'', Hagrid originally stated he had to "give Sirius his bike back". This was later contradicted by ''Literature/HarryPotterAndThePrisonerOfAzkaban'' where Sirius gave the bike to Hagrid and told him to keep it before disappearing. Later editions of ''Philosopher's Stone'' rectified this by having Hagrid just say he had to put the bike away.
** Early editions of ''Literature/HarryPotterAndTheChamberOfSecrets'' have Dumbledore tell Harry that Voldemort is the last living ''ancestor'' of Salazar Slytherin, even though [[YouKeepUsingThatWord the word "descendant" was obviously meant]]. This was of course eventually changed, but not before inspiring some [[CrackFic humorous]] EpilepticTrees. Also in the same book, Lockhart mentions that one of the less-than-photogenic people he stole credit from was a witch with a "harelip" (an outdated term for a [[https://en.wikipedia.org/wiki/Cleft_lip_and_palate cleft lip]]), which was changed to a "hairy chin" in later editions.
** In the first American printing of ''Literature/HarryPotterAndTheGobletOfFire'', a mistake made by Rowling (in both the British and US-market editions) made it so the order in which the shadows of Harry's parents come out of Voldemort's wand contradicts the order in which Voldemort said he killed them, launching a thousand EpilepticTrees. This was corrected in later editions.
** In the original edition of ''Literature/HarryPotterAndTheOrderOfThePhoenix'', it's a minor plot point that prefects can't take house points. However, this contradicts an earlier scene in ''Chamber Of Secrets'' in which Percy takes points off Ron. Later editions of ''Phoenix'' altered the dialogue so that the rule is that prefects can't take points off other prefects.
* In ''[[Literature/AnitaBlake Narcissus In Chains]]'' by Laurell K Hamilton, the hardcover version of the book contained a scene where the main character was raped. All other editions of the book have had edits made so that it's merely questionable as to how willing she was (mostly dialogue changes so that she's not flat out saying "no I don't want to.")
* The ''Literature/NancyDrew'' and ''Literature/HardyBoys'' series underwent a major retcon of their first stories beginning in 1959 (the first 34 for Nancy, 38 for the Hardys). Ostensibly to remove dated slang and racist stereotypes, and also to make the stories shorter and faster-paced, this led to a realization that some stories simply fell apart otherwise, so more than a few of the books were completely new stories with nothing but the title being the same. Purists of the two series have criticized the revised books as being bland and sanitized. The original volumes can be found through reprints from niche publisher Applewood Books.
* A reissue of ''Literature/HuckleberryFinn'' in 2011 omitted the N-words, exchanging the word "slave" where appropriate.
* Creator/AgathaChristie's book ''Literature/AndThenThereWereNone'' was originally called ''Ten Little Niggers'' in the UK. Then it was ''Ten Little Indians'' before that term for Native Americans fell out of politically correct language, resulting in its current title. In the novel, the rhyme was changed from ''Ten Little Niggers'' to ''Ten Little Indians'' to ''Ten Little Soldier Boys'', and the name of the island from ''Nigger Island'' to ''Indian Island'' then to ''Soldier Island''. The U.S. edition has always used the title "And Then There Were None".
* In ''Literature/TheLorax'' there was originally a line that joked about how polluted Lake Erie was. Some environmentalists pointed out to Dr. Seuss that there were efforts to clean up the lake. So reprints have changed the Lake Erie line. It can still be heard in the AnimatedAdaptation however.
* The "Literature/{{Fudge}}" books by Creator/JudyBlume were edited in post-2002 reprints to, among other things, replace references to ''Series/TheMuppetShow'', ''Series/SesameStreet'', and ''Series/TheElectricCompany1971'' with references to the Creator/CartoonNetwork and Creator/{{Nickelodeon}}, replace vinyl record players with CD players, and in ''Sheila the Great'', change the reason the characters are using a mimeograph machine (in 1972, it was because they hadn't gotten a copier yet. In 2002, it was because the copier broke).
* ''Franchise/JurassicPark'' was slightly edited after ''Literature/TheLostWorld1995'' was published to remove reference to Dr. Malcolm's death, to support his retcon back into existence for the sequel.
* In ''Just Me and You'', the first of Mercer Mayer's "Little Critter" books, at one point, Little Critter is threatened with being spanked. This was changed in recent reprints to have him being threatened with getting a "time-out".
* ''Literature/TheBabySittersClub'' was revised somewhat in later printings, as editors tried to reconcile a few inconsistencies made by Ann M. Martin and ghostwriters:
** In the original ''Kristy's Big Idea'', Kristy is described as wearing a skirt and blouse. As Kristy would later be established as only liking sweaters and jeans, this detail was changed to fit that. Her mother's name was also originally given as "Edie Thomas", but as Martin later referred to her as "Elizabeth", this was also corrected in later editions.
** Karen's mother and stepfather were originally named "Sheila" and "Kendall" in ''Kristy's Big Day''. Reprints corrected their names to be "Lisa" and "Seth", the names that Martin would settle on when writing ''Baby Sitters' Little Sister''.
** An early edition of one ''Little Sister'' book had Karen concoct various plans of revenge on a boy that bullied her. One idea was her saying that she'd tell him he was adopted. After parents complained about the implications of that passage, this was changed to Karen's plan being "Tell him I will never ever speak to him again".
* Reprints of the Norwegian edition of the Literature/PippiLongstocking books by Creator/AstridLindgren rewrite Pippi's father's title from "negerkonge" (Negro King) to "sydhavskonge" (King of the Southern Seas), due to the, well, you know what.
* ''Literature/{{Imaro}}'' when first released in 1981 had a chapter called "Slaves of the Giant-Kings" with {{Fantasy Counterpart Culture}}s of the Tutsi and Hutu of Rwanda and Imaro incites a bloody rebellion against the Tutsi. Then in 1994 the Rwandan Genocide happened where the Hutu slaughtered the Tutsi. When author Charles Saunders finally reprinted ''Imaro'' in 2006 he removed "Slaves of the Giant-Kings" entirely, replacing it with "The Afua". In addition, Saunders moved the chapter "The City of Madness" to the start of ''Imaro 2: The Quest for Cush'' and replaced it with "Betrayal in Blood" since in the original publication there was a large gap between "The City of Madness" and the preceding chapter while "Betrayal in Blood" bridges that gap.
* ''Darkspell'', the second book in the ''Literature/{{Deverry}}'' series, was later released in a revised edition. Some of the changes were made to bring the book more in lime with how the author originally envisioned it, before her editor overruled it. For instance, Sarcyn is redeemed in the new version instead of going insane and his brother has been replaced with a sister, whose role has been drastically reduced. Also, the ThievesGuild in one town was changed into just a father and his son, because the athor came to realize that the town wasn't large enough to support a fully-fledged thieves' guild.
* Older books in the KidDetective series ''Literature/TheThreeInvestigators'' were reedited to replace Creator/AlfredHitchcock with fictional stand-ins after the RealLife Hitch's death.
* After much demand from fans, and profiteering by secondhand book dealers, Creator/TerryPratchett's first novel ''Literature/TheCarpetPeople'' was eventually republished. However, it was heavily rewritten, partly to remove bad writing but also to replace the conventional HighFantasy monarchism and glorification of war of the original with the more democratic and pacifist political outlook of Pratchett's mature novels.
* Recent reprints of the older ''Literature/GeronimoStilton'' books have many illustrations replaced or partially redrawn to replace Trap's old design[[note]]White shirt, red suspenders and blue pants[[/note]] with the one introduced around volume 31-32 of the main series[[note]]Yellow and green Hawaiian shirt, reddish brown shorts, and also an earring and a ponytail[[/note]]. The partially redrawn ones [[SpecialEffectFailure are the most obvious ones]], since the new, digitally colored parts are drawn over the original watercolored pictures.
* The second book of the ''[[Literature/TheBookOfTheDunCow Book of the Dun Cow]]'' series, ''The Book of Sorrows'', was rewritten and reissued some time later as ''Lamentations''. The new version differs in writing style, changes various plot points, and both introduces new characters and removes existing ones from ''Sorrows''. This was to bring the series in line with the final book, ''Peace at the Last'', which followed the rewritten continuity.
* The biggest modern revisions made by Creator/JinYong, ''Literature/DemiGodsAndSemiDevils'' now ends with Wang Yuyan rejecting Duan Yu, opting to stay and take care of her now crazy cousin, Murong Fu, Duan Yu marrying all his previous romantic interests and a few other retcons.
* Two different works by Creator/MichaelMoorcock were edited in later editions, because the first editions appeared to endorse rape in certain circumstances and Moorcock was convinced by feminist criticism that this was morally wrong:
** In the ending of the first edition of ''Gloriana'', Quire successfully gives Gloriana her first ever orgasm and ends the [[FisherKing barrenness of her kingdom]] by raping her. In later editions, when he tries to, she overpowers him and [[DoubleStandardRapeFemaleOnMale rapes him]] with the same result.
** At the end of the first version of "The Transformation of Miss Mavis Ming", the Fireclown cures Mavis of her uptightness and right-wing politics by raping her. In later editions, he does it by whipping her until she has an emotional breakdown, which may or may not be an actual improvement.
* In ''Literature/TheStormlightArchive'' book ''Literature/WordsOfRadiance'', the climactic battle between [[spoiler:Kaladin]] and [[spoiler:Szeth]] was rewritten: after [[spoiler:Szeth learns that his terrible crimes were AllForNothing]], the original hardcover has the former kill the latter, while the paperback release has [[spoiler:Szeth choose to fall to his death in the Highstorm]]. In both editions, [[spoiler:he's brought BackFromTheDead anyway]].
* Creator/IsaacAsimov's ''Literature/TalesOfTheBlackWidowers'' contains an introduction where he admits that he's rewritten several of the stories compared to their original printing, mostly due to the way the stories sound redundant when describing characters the same way in short succession.

[[folder:Live-Action TV]]
* An episode of ''Series/LawAndOrder'' featured a mass murder at a bar called "The Velvet Room". After the owners of an actual New York bar of that name sued, the episode was redubbed to change the name of the bar to "The Vivant Room".
* The picture of Penny & Desmond in the ''Series/{{Lost}}'' episode "Orientation" originally showed Henry Ian Cusick with a model who was not Sonya Walger. On the DVD, the photo has been digitally altered to include Walger (and was edited for the rerun as well).
* The re-filming of earlier episodes of ''Series/{{Seinfeld}}'' when Frank Costanza was recast. Also, the first episode featuring Newman had him voiced by Larry David, as he did not appear on screen. Reruns of the episode feature Wayne Knight's voice instead.
* Happened a few times on ''[[Series/BabylonFive Babylon 5]]''. Generally this was done to fix a mistake that was detected almost immediately after the first airing, such as Sheridan's old ship (the ''Agamemnon'') opening fire on civilian transports in "Moments of Transition" (changed to the ''Pollux'' later), and Sheridan's notorious reference in "Comes the Inquisitor" to the UsefulNotes/JackTheRipper murders happening in the "West End of London". Also, all official releases of the original pilot "The Gathering" are the "Special Edition"; the original pilot (as originally aired) is a case of KeepCirculatingTheTapes.
** Averted with the recasting of Anna Sheridan. After Melissa Gilbert played John Sheridan's (Bruce Boxleitner, Gilbert's real-life husband) wife Anna in a pair of third-season episodes, Creator/JMichaelStraczynski considered doing a reshoot with Gilbert of an earlier second-season scene featuring Anna Sheridan (originally filmed with a different actress), but it never actually happened.
** Interestingly enough, some refilmed footage is clearly visible, as there was a FlashbackWithTheOtherDarrin in "Z'Ha'Dum". Also lampshaded in the Director's Commentary.
* At the beginning of ''Series/{{Heroes}}'' Season Three episode "I Am Sylar", the "PreviouslyOn..." segment shows a scene in which Danko instructs Sylar to shapeshifter into Agent Taub for a while. However, this never actually happened "Previously on Heroes". It was, in fact, an entirely new scene that according to the writers was written and shot for the sole purpose of being placed in the recap.
* ''Series/{{Battlestar Galactica|2003}}'' became infamous for including deleted scenes in its "Previously On" sequences, or just throwing in extra dialogue when a character's face wasn't visible.
* ''Series/SonsOfAnarchy'' inserted a line in a "Previous On..." wherein the character of Cherry who had been explicitly [[PutOnABus Put on a Bus to Canada]] is told she will be "safe in Ireland," to set up her [[TheBusCameBack three episode guest appearance]] while the club goes to {{Oireland}}.
* The original LP for the soundtrack of ''Series/BattleFeverJ'' depicted Battle France wearing the light blue suit he wore in early episodes. The later CD version, first printed during the [=1990s=], changed to the white suit he wore in later episodes.
** Episodes 13, 5, and 7 have two versions: the original, in which Kenji Ushio plays Hedder, and the other in which he has been replaced by Masashi Ishibashi
%%* Even the fans have complained about ''Series/{{Glee}}'' changing facts to fit the episode.
* At the end of the first season of ''Series/{{Sherlock}}'', John's CharacterBlog stopped dead, with increasingly worried comments from his friends, none of whom had seen him since the CliffHanger. When the second season revealed [[spoiler: the cliffhanger was resolved very simply within seconds]], the blog was quickly changed to fit the new events.
* Some of the {{Missing Episode}}s in ''Series/DoctorWho'' have been reconstructed with animation, which was used in at least one case to do this - the "Bad Wolf" ArcWords from the 2005 series actually show up in "The Invasion", a 1968 story.

* Mark Ronson's ''Uptown Funk!'' had co-writer credit given to Trinidad James from sampling ''All Gold Everything'', The Gap Band for similar elements to ''Oops, Upside Your Head'', and the producers involved with all three bands.
* Music/MichaelJackson did this twice and didn't announce it. After the success of the Rock With You single - which was itself a remix, as was the B-Side Get On The Floor - the album Off The Wall was reissued with the single mixes replacing the album versions, unannounced, which remains to this day. The same thing happened with the album Bad, which had numerous differences, most notably a spoken intro to I Just Can't Stop Loving You. The 2001 remasters presented retained the revised tracklistings. Enough people kicked up a fuss about the Bad album being changed that the original mix (albeit remastered) was reused for Bad 25.
** Michael had three changes to his albums that were announced, however - Ben had the cover changed to remove the rats (Ben is supposed to be Michael's pet rat) because they were apparently scaring kids, History was revised to contain an edited version of 'They Don't Care About Us' (due to containing the line 'jew me, kike me' which was considered offensive), and Off The Wall's cover was changed to just showing his lower half on the US pressings and the 2001 remaster because it was thought that younger fans would not realise it was the same Michael (prior to his skin bleaching and hair straightening).
*** After Michael's death, newspapers that had accused him of being a pedophile stopped doing so and praised him instead, acting like there had never been any accusations. This naturally confused their audiences, some of whom were quite vocal about it.
* ''Stay With Me'' by Sam Smith, James Napier and William Phillips had similarities to ''I Wont Back Down'' by Tom Petty and Jeff Lynne, who were retroactively given co-writer credit on ''Stay With Me''.
* Wham's 2011 reissue of The Final (with a DVD of the video release) presented it as the 'original album' and played on the nostalgia of people who would have bought it on vinyl or cassette in 1986. However, the reissue is based on the CD release, which was released later and doesn't contain Blue (Armed With Love), the extended mixes of Bad Boys, Careless Whisper and I'm Your Man. As Blue is pretty rare on CD, this was widely seen as a missed opportunity.

[[folder:Newspaper Comics]]
* It's very common for books of newspaper comic collections to revise, edit, or just outright omit comic strips the artist disliked on first run. Since it's quite difficult to track down "original" strips as they first ran in newspapers, this is one form of media where Orwellian Retconning can be almost undetectable and thus extremely successful.
** In ''The Prehistory of TheFarSide'' Gary Larson admits to doing this on several occasions. For example, one comic involved a vampire watching a TV ad boasting "when you're out of A-positive, you're out of blood!" with the caption "Your Vampire TV station." Larson admitted finding that caption redundant, and sure enough it never accompanies the comic in any other Far Side collection or calendar.
* This was played with in a ''ComicStrip/{{Dilbert}}'' comic, when Topper says he passed a gallstone so big it became the Secretary of Labor in the Clinton Administration.
-->'''Receptionist:''' I find that hard to believe.
-->'''Topper:''' Give me ten minutes and then check Wiki/{{Wikipedia}}.

[[folder:Professional Wrestling]]
* Ever since the World Wrestling Federation were forced to change their name to [[Wrestling/{{WWE}} World Wrestling Entertainment]] in 2002, they've made sure to remove all references to the letters WWF and the "Federation". This is partly because of not being allowed to use the acronym for legal reasons, and wanting to make the rebranding as absolute as possible. Which means that older wrestlers like Wrestling/RandySavage are referred to as "former WWE wrestlers", even if their runs with the company took place long before the name change, and making edits whenever a wrestler or announcer mentions "WWF" on DVD releases of pre-2002 footage. Averted on the UK licensed [=DVDs=] which, through some legal loophole, can be released unedited. Averted with the release of the WWE Network, as footage from the WWF days can be found there unedited due to a licensing agreement between them and the World Wide Fund for Nature.
* Trisa Hayes had appeared in ''Penthouse'' some time prior to her surprise Wrestling/{{ECW}} debut as Wrestling/{{Beulah McGillicutty}} at ''ECW Hostile City Showdown 95''. However, because WWE had a working relationship with ''Playboy'' at the time that the ''Rise & Fall of ECW'' [=DVD=] was released in 2004, Wrestling/TommyDreamer had to say that she had been a ''Playboy'' Playmate. For the record, Tommy Dreamer, real name Thomas Laughlin, is ''married'' to Trisa Hayes in RealLife. Yes, WWE made Tommy Dreamer lie about what magazine his ''wife'' had appeared in prior to her ECW debut.
* When [[Wrestling/SidEudy Sid Justice]] eliminated Wrestling/HulkHogan at ''Royal Rumble 1992'', fans cheered and Wrestling/GorillaMonsoon responded as if it was fair. While the home video version kept the original reaction and commentary, the recap on ''Superstars'' in the weeks after was edited to remove the cheering, and Monsoon actually re-recorded his commentary to cast Justice in a [[FaceHeelTurn negative light]].
* Normally, the debut of a company's new logo would be greeted with much fanfare. However, when Wrestling/{{WWE}} decided to update their [[TheArtifact "scratch" logo]] into a more modern, sleeker logo, there was not one mention of the new logo made on-air, despite it replacing the old WWE logo on almost everything (microphones, stage, announce table, backstage interview area, turnbuckles, the patch on the referees' shirts, etc.). Making it doubly bad is the fact that the supposedly "new and improved" WWE Championship was to be revealed that night, but what was revealed was a belt exactly the same as the old WWE Championship, only with the new logo instead of the old. So in {{Kayfabe}}, no one exactly knew what was so new and improved about the belt, as it was never mentioned by anyone on air.

[[folder:Role-Playing Games]]
* Given the nature of Website/{{BZPower}}, wherein players can edit their own posts at will, this has taken place every now and then in {{R|olePlayingGame}}PGs such as ''Roleplay/AlphaTeamMissionDeepFreezeRPG'' or ''Roleplay/DinoAttackRPG'', usually when a player is adding in a piece of information he originally forgot or when a player is decanonizing something he wrote. For example, in ''Dino Attack RPG'', Dr. Cyborg's revelation of Pterisa's origins vanished without a trace after Andrewnuva199 asked avmatoran to retcon it.

[[folder:Tabletop Games]]
* When ''TabletopGame/{{Warhammer 40000}}'' ended the Squat race, reprintings of books where Squat characters appear had them deleted, turned into humans or Ratlings although they do get a mention since the sixth edition rulebook.
* Done humorously with the ''TabletopGame/{{Paranoia}}'' franchise, where the much-reviled fifth edition of the game has been officially declared an unproduct.

[[folder:Video Games]]
* While most content updates in ''VideoGame/CityOfHeroes'' added new missions and story arcs, there were occasions when the developers would go back and redo existing missions that were badly designed (making them very unpopular with the players) or that were contradicted by changes to the game lore. The infamous Positron Task Force was completely rewritten from the ground up after years of overwhelming negative feedback from players.
** This also could happen frequently with the Mission Architect feature as it was possible for the author to edit a story arc that they have published without taking it down and republishing. The arc still had the same ID number and player ratings, but could very well have been changed into a completely different story if the author so chose.
*** Sometimes this was necessary as a exploit fix could have unintended consequences for authors who didn't try to write farming missions and now had to make changes to fix their damaged story arc.
* ''Franchise/DragonAge'': [[TheChurch The Chantry]] is well-known to rewrite historical documents to suit whatever politics it has at the time--particularly mage and/or elven heroes.
** While the EnslavedElves fought with the humans' prophet [[CrystalDragonJesus Andraste]] to free Southern Thedas from [[TheEmpire Tevinter]], after the Exalted March against the (Elven) Dales, the Chantry [[UnPerson stripped the elven general Shartan from the Chant of Light]], and {{race lift}}ed [[spoiler:Ameridan, an elven mage Inquisitor]] to support their on-going anti-elf propaganda.
** They also tend to erase or downplay the heroic accomplishments of mages, since the Chantry derives a lot of power from convincing the common folk that their [[KnightTemplar Templars]] (whom they keep [[FunctionalAddict addicted]] to [[FantasticDrug lyrium]], which the Chantry has cornered the market on) are the commoners' only protection against dangerous magic-users (who they claim, if left unchecked, could create another [[TheEmpire Tevinter]]).
** In ''VideoGame/DragonAgeInquisition'', if the [[PlayerCharacter Inquisitor]] is male and in a romance with [[GayOption Dorian]], Dorian can remark at one point that he wonders how long it will be before the Chantry writes ''that'' part out of the Inquisitor's exploits?
* A couple of changes were made to ''VideoGame/{{Portal}}'' for its ''ARG'' leading to the announcement of ''VideoGame/{{Portal 2}}''. Specifically the ending was altered and a series of radios were added to the game with an accompanying achievement to find the locations where all the radios received a signal.
* ''VideoGame/{{Fallout 3}}'' had some changes made by its "Broken Steel" DLC (and by extension the Game of the Year Edition). Mostly to address [[PlotHole complaints]] about the ending.[[note]]The biggest one being why you couldn't send in one of the several companions you might have following you at the time who were either immune to radiation or blindly loyal/brainwashed enough to obey you [[spoiler:into a radioactive area to save the day (one of which had already used his immunity to radiation to retrieve a MacGuffin from another radiation flooded area when you first met him).]] [[GoodIsDumb Although you still have to do it yourself if you want to be "good"]].[[/note]]
** The last part was probably due to them not wanting to have Creator/RonPerlman record another ending cutscene for this eventuality.
* The later ports of ''VideoGame/MetalGear'' and ''VideoGame/MetalGear2SolidSnake'' renamed many of the characters specific to those two games. The re-releases of ''Metal Gear 2'' in particular also changed all of the realistic character portraits into ones drawn similarly to the style of ''VideoGame/MetalGearSolid'' illustrator Yoji Shinkawa, since all of the portraits in the [=MSX2=] version were trace-overs of real-life celebrities (which could've led to Konami facing legal problems if they were kept due to the unauthorized use of people's likenesses). Even the Japanese Virtual Console release of ''Metal Gear 2'', which is otherwise an emulation of the [=MSX2=] game, uses the Shinkawa-style portraits.
* The [=10th=] anniversary re-release of the ''[[VideoGame/ResidentEvilCodeVeronica Wesker's Report]]'' documentary removed the line in which Wesker claims that Sherry is in his organization's custody. This was meant to {{foreshadow}} [[AbortedArc a plot development for a future game that was later abandoned]].
* The GBA re-release of ''VideoGame/TheLegendOfZeldaALinkToThePast'' rewrites Link's uncle's dying speech to remove the infamous "Zelda is your..." line. A MythologyGag, however, has a BonusBoss that gives a more accurate translation of the original Japanese line ("You are... the princess's... ... ... ...") right before attacking. Also the "seven wise men" were changed to "Seven Sages", to be consistent with ''VideoGame/TheLegendOfZeldaOcarinaOfTime'', especially since it reveals only two of them actually ''are'' men.
* Originally, the Gerudo symbol in ''VideoGame/TheLegendOfZeldaOcarinaOfTime'' was a crescent moon and star, very similar to the symbol of the Islamic faith. Also, the text of the OminousLatinChanting in the Fire Temple was originally an Islamic prayer. Both were changed in subsequent releases of the game to remove the Islamic references entirely. Also, to maintain the E rating instead of getting bumped to T[[note]]E10+ didn't exist yet[[/note]], Ganon's blood shed during end-game cutscenes was changed from red to green.
* ''Videogame/{{Submachine}} 1: The Basement'' is actually the third version of the original ''Submachine''. Amongst the changes are the inclusion of a teleporter device and a Wisdom Gem, both fundamental concepts in the later ''Submachine'' games.
* As with the anime/manga example above, any attempt to {{Macekre}} a video game from Japan, South Korea and Europe could be seen as an attempt at this by some game players.
* ''VideoGame/MassEffect3'' altered and expanded on its ending after major fan backlash. Most of the changes were done to avoid any {{Inferred Holocaust}}s, make the endings more bittersweet than unintentionally bleak, and give a bit more insight into how the final choice shaped the universe. The reaction to these changes were mostly positive. The ''Leviathan'' [=DLC=] goes even further and has [[spoiler:the eponymous Leviathans mentioning the AI behind the Reapers, the Catalyst, which has relatively no build up in the main game]].
* Creator/{{Nintendo}} and Creator/GameFreak received criticism over Jynx's design in the ''Franchise/{{Pokemon}}'' franchise over her similarity to the blackface stereotype. (This was not intentional--but what Jynx is ''really'' based on is controversial itself.) They resolved this issue by changing Jynx's face from black to purple, including for remakes of old games, as well as promptly replacing any images of Jynx with a black face with new artwork where her face is purple wherever possible and recoloring the episode of [[Anime/{{Pokemon}} the anime]] that started up the whole debate. This proved futile with the English dub, though (see Anime & Manga section above).
* ''VideoGame/StarTrekOnline'': After the ''Legacy of Romulus'' ExpansionPack launched Cryptic started going back through the early missions and tweaking them, culminating in season 9's complete rewrite of the Borg and Undine episodes as one episode titled "Borg Advance". While most of the changes were fairly well-thought-of, "Where Angels Fear to Tread" (formerly "The Return") had what was previously an ordinary Romulan Star Navy captain fiddling with Borg tech[[labelnote:*]]something Starfleet and the KDF have been doing, too[[/labelnote]] get retconned to be a [[StateSec Tal Shiar]] officer who was [[KickTheDog experimenting on Romulan Republic POWs]]. This made the moral choice (left over from the previous version) of what to do with her and the Borg tech she's experimenting on no actual choice at all.
* In the UsefulNotes/GameBoyAdvance and most later ports of ''VideoGame/FinalFantasyVI'', the scene in which Locke meets Celes is censored to remove the Imperial soldiers beating her onscreen, which Squaresoft considered necessary in the age of video game ratings systems in order to get the desired rating in Japan.
* This trope is what fuels the fight between the Ishgardians and Dravanians in ''VideoGame/FinalFantasyXIV'' -- [[spoiler:the Ishgardians and Dravanians lived in peace after they saw the awful price Hraesvelgr paid when he was forced to eat the human Shiva. However, King Thorion I and his Knights Twelve, seeking the power of the dragons, slew Ratatoskr and ripped out the eye of her brother Nidhogg. The king and half the knights were killed by Nidhogg and the remaining knights stole away with Nidhogg's eye and claimed Rataoskr's power as their own. When the Dragonsong War started, the Church lied as to who started the war, claiming the dragons betrayed them instead. This remained a secret until the PlayerCharacter and the remains of the Scions of the Seventh Dawn make their way to Ishgard to hide from the Brass Blades and Crystal Braves after they are accused to regicide.]]

* The ''WebAnimation/BonusStage'' episode "2 Fast" has a ChooseYourOwnAdventure[=-=]style ending, and included in the options is "Creepy Ending". Originally this involved Elly and a [[GenderBender female Joel]] waking up in bed with Phil. Apparently fans were disturbed by this, as Joel says in the following episode, so Elly's mouth was removed and the figures were changed into puppets.

* Not that Orwellian, but ''Webcomic/BustyGirlComics'' changed a few words in an [[http://bustygirlcomics.com/post/25633202221/bonus-comic-because-i-had-to-do-my-take-on-this early strip]] to try to be more inclusive of [[http://bustygirlcomics.com/post/26104828446/your-boobs-are-something-youre-supposed-to-be-proud diverse feelings]] on busts. Since Tumblr archives previously uploaded versions of images, you can compare the [[http://25.media.tumblr.com/tumblr_m60b0pkhJD1rone1bo1_1280.jpg original]] to the [[http://25.media.tumblr.com/tumblr_m60b0pkhJD1rone1bo1_r1_1280.jpg more cautiously framed]] version.
* ''Webcomic/EightBitTheater'': Thief's uniform turns red shortly after he changes class to Ninja. Then it turns black to make him more like a traditional ninja (and because Fighter and Red Mage are already very, very red). When the other warriors call him on it, he claims it's always been black... and when that comic went up, the author went back and edited ''every single page'' in which Thief is wearing the ninja uniform (even some very old pages, where Thief is wearing the ninja uniform in {{Flash Forward}}s or {{Imagine Spot}}s), to make that uniform black.
* There is a device in ''WebComic/CityOfReality'' that is made to do ''this and this alone''. It is brought to Reality by a thief who uses it to predict the every move, and later used by Hawk, who uses it to be "perfect" at everything, until it falls back into the thieves hands. Later, it turns out it was [[ArtifactOfDoom causing freak storms threatening Reality]].
** The same device is later used by the reader in a dark ChooseYourOwnAdventure in Magic World.
** And then used by [[CardCarryingVillain saboteurs]] trying to steal [[AppliedPhlebotinum crystals]] from all the worlds at once. The first time, they failed due to the high security, but the second time around, they knew exactly what to do. The characters are still dealing with the fallout.
*** This last one is the only one that was actually retconned into the comic, with the original version available off-site. All other instances were treated as regular MentalTimeTravel.
* ''Webcomic/SchlockMercenary'' quotes from a book called ''The Seventy Maxims of Maximally Effective Mercenaries''. Originally, this was ''The Seven Habits of Highly Effective Pirates'', until Franklin-Covey, owners of the actual ''Seven Habits of Highly Effective People'', noticed and sent what can only be described as a very polite [[ThatWasntARequest cease and desist notice]]. Luckily, Tayler took it in stride since the change meant he could finally make [[TheMerch Merch]] based on the quotes without a potentially harsher letter.
* The print release of early chapters of ''Webcomic/ElGoonishShive'' changed a few things (which were later changed in the archive as well) away from throwaway gags and/or revealing too much. Such as [[http://www.egscomics.com/?date=2002-02-17 Grace's reaction to Tedd's invitation]] (first version didn't fit her InnocentFanserviceGirl character), [[http://www.egscomics.com/?date=2002-06-27 Susan's reaction to meeting "Ellen" fElliot]] (first version sounded ''really'' out-of-character, with Susan calling "Ellen" "cutie") and [[http://www.egscomics.com/?date=2002-06-30 a conversation between the same fElliot and Sarah]].
** Also one discussed meta-example [[http://www.egscomics.com/?date=2012-09-03 where Jimmy summarizes]] the history of ''Franchise/StarWars''.
* In ''{{Webcomic/Erfworld}}'', Bogroll's special ability was Regeneration and Deletionism was a school of magic for Naughtymancy along the Numbers axis, but was completely changed in the archives and books so that Bogroll now had Fabrication and Naughtymancy/Numbers was now "{{Retconjuration}}". Deletionism and Regeneration now only exist in the memories of fans (and the wiki). WordOfGod said that this was [[http://www.erfworld.com/2009/08/the-ultimate-naughtymancy/ because he hadn't thought the special abilities system through at that point]].
* ''Webcomic/{{Starslip}}'' was originally called ''Starshift Crisis'', but copyright issues with ''[=StarShift=]: The Zaran Legacy'' caused the starshift (the in-universe [[FasterThanLightTravel transportation method]]) to be [[{{Retcon}} retconned]] as the "starslip", and all references in the archives were changed.
* The author of ''Webcomic/MeatyYogurt'' had previously written [[Webcomic/YumeDream another comic]] featuring a character with an odd eye. After feeling that an eye scar in Meaty Yoghurt was too reminiscent of this character, she redrew all the character's appearances with a lip scar instead.
* In ''Webcomic/GunnerkriggCourt'', a few bits of dialogue in the first two chapters were quietly changed, a year or two after they first went up. For example, on [[http://www.gunnerkrigg.com/archive_page.php?comicID=7 this page]], "''homme de fer''" was changed to "tin man" because Tom thought the French was gratuitous. Oddly enough, some further changes were made for the first volume of the print edition, but these weren't incorporated into the online archives.
* ''Webcomic/{{Homestuck}}''. Andrew Hussie stated that the playable human characters are supposed to be a-racial, so readers could imagine them as any race they prefer. When a reader pointed out an old page on which one of these characters was referred to as a "[[PrettyFlyForAWhiteGuy white rapper]]", Hussie went back and replaced the word "white" with gibberish. [[note]][[WordOfGod The author has stated he had done this as a joke.]][[/note]] Soon afterwards, he changed it to "a white guy who is a rapper".
** Occasionally panels are posted with unintentional errors, which are quietly corrected by the author shortly afterward. For example, when the Bec's Head Base first appeared it had the troll's Sgrub logo. It was quickly changed to the standard Sburb logo. The Sufferer's death was initially depicted with less detail, and soon had more muscles and lines showing the cut of his clothes added. Another example was in a flash where [[spoiler: the deceased Nepeta]] was shown without the ProphetEyes of dead characters. This was also corrected, dashing hopes of a resurrection. Amusingly the opposite happened in a flashback panel where two characters that were alive at the time of the flashback were shown with ProphetEyes - again, this was fixed.
** Overlapping with CutSong: A dispute with a (now former) member of the music team caused a few existing flash animations to be re-done with new music. In another example, a composer had his songs removed from the fifth music album after he was caught plagiarizing. It happened again when a winner of the fan music contest did the same thing.
** Another race incident happened after one of the a-racial, DeliberatelyMonochrome human characters got a "ridiculous game powerup" that involved a wacky palette, including peach-toned skin...and described it as feeling "Caucasian." This was initially done deliberately by the writer [[LampshadeHanging to poke fun at the issue]], but some readers took it as an excuse for harassment, leading him to rewrite the line as "[[{{Pun}} peachy]]".
-->'''Andrew Hussie:''' [[http://web.archive.org/web/20130114104615/http://mspandrew.tumblr.com/post/40461873904/more-so-i-just-dialed-down-the-joke-on-page ...what motivates me more to revise it is noticing more than a few unsavory individuals using it as justification to harass [=POCs=] or anyone who, reasonably, wanted to voice their concerns.]] On reflection Id rather not have my decisions serve as fodder for the arguments of such people. They dont speak for me. As a humorist, and someone who writes a provocative and unpredictable story, there are many types of unpleasant responses to my stuff I can easily accept. But some types...maybe not so much.
** And a huge one with [[spoiler:John reaching through a hole in the universe and poking his arm into a number of past panels and even a couple of flashes - all of which now have his arm inserted into them if you go back and check]].
** And again with [[spoiler: oil being zapped all over past points in the comic by the same]].
* ''Webcomic/TheAdventuresOfDrMcNinja'''s "Issue One Half" and "There Is A Raptor In My Office" originally had Doc dealing with a villainous Ronald [=McDonald=] and the [=McDonald's=] corporate empire. [="AWOL MD"=] has him showing up again as [[NoCelebritiesWereHarmed Donald McBonald]] - going from EnemyMime to straight-up MonsterClown as a result - and both the previous issues were altered to feature [[BlandNameProduct "McBonald's"]] references.
* Invoked but averted when Bedivere stops being {{Gender Flip}}ped in ''Webcomic/ArthurKingOfTimeAndSpace''; the characters say it'll only happen as long as no-one expects the management to go back and redraw all the previous strips he appeared in. A later retcon establishes he's trans, so the previous strips of him appearing female ''are'' in continuity.
* John Troutman has been ''very'' careful to expertly hide his earlier comics (except for ''Vigilante, Ho!'' and the second-incarnation ''Sporkman'' strips) from the Internet, to the point that the FAQ for ''Mary Elizabeth's Sock'' has a question of whether the characters have been seen before, to which he responds that [[MetaphoricallyTrue some of them have been in Lit Brick and Sporkman]] (neglecting to mention nearly all were in, and most originated in, ''Basil Flint, P.I.'', ''Andiewear'', ''Felicity Flint, Agent From H.A.R.M.'', ''Flint Again'', and/or ''Flat Feet and High Heels'').
** Currently being [[SubvertedTrope subverted]] with [[http://redux.troutcave.net/ Troutcave Redux]] in which the Trout is reposting the entirety of his original archives, one strip a day, with [[OldShame often brutal commentary on his past self's failings.]]
* ''Webcomic/MenageA3'' experienced an unusual retroactive adjustment, in that it became ''less'' censor friendly, when the creators got tired of having to apply a SceneryCensor to the strip's extensive nudity, and went back over early strips adding nipples and such.
* A couple of early ''Webcomic/QuestionableContent'' strips have been edited since they first appeared. See the series' trope list for details.
* An early strip in ''Webcomic/BetweenFailures'' has Thomas using "queer" as a pejorative, which was later edited to a different insult. The creator discussed his reasons in that page's comments section - mainly that Thomas was planned to have a bad tendency to "kick down" due to his general anger and frustration in life, and that he was supposed to eventually confront and grow out of such insults. In practice, Thomas mellowed considerably faster than originally planned and so the bad habit and planned storyline went way out of tone for him and had to be discarded, with the creator going back to snip off the dangling thread.
* ''Webcomic/SisterClaire'' did this for the first few comics due to Yamino not being satisfied with how the original pages turned out and some of the more juvenile humor at the time which contrasted greatly with later events of the story. As such the new pages tone down these bits and add some more context to the characters.
* In ''Webcomic/EerieCuties'', Blair using an ArtifactOfDoom to make Brooke and Nina [[GirlOnGirlIsHot make out]] got such an outcry from the fans that it was changed to him forcing Brooke to do a cheerleader routine instead.
* In ''Webcomic/DangerouslyChloe'', Abby originally looked significantly younger in her first appearance; the comic in question was edited before the next update for unclear reasons. Also, Lacy's dialogue originally suggested her lesbian parents would be disappointed with her if she started dating boys - this was changed after fan outcry to her just wanting to emulate them.
* Chris-chan had made many retcons in ''WebComic/{{Sonichu}}'' (such as changing names on those based on real people), but the ones made in September 2015 were noticeable. Issues 9 and 10 were altered to be less homophobic, such as replacing the infamous [[CureYourGays cure for homosexuality]] plotpoint with a cure for "Nombie-Zazis", although some details such as the need for Chris' "straight blood" were still left in tact.

[[folder: Web Original]]
* Season 1, episode 3 of ''Podcast/{{Tanis}}'' refers to the real-life case of Elisa Lam, who drowned in a hotel's water tower under mysterious circumstances. The podcast presents a fictional conspiracy theory that Lam had been possessed by a [[MentalTimeTravel future-flung]] Aleister Crowley. After [[TooSoon outcry from the listeners]], the episode was re-released with all instances of Lam's name bleeped. However, it's still obvious who's being discussed, what with the infamy of the case and references to Crowley writing about a historical figure named Siela (pointed out as an anagram of "BLEEP") and contacting an alien named Lam (not bleeped).

[[folder:Western Animation]]
* In ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', an AscendedExtra known affectionately among fans as Derpy was given a scene which not only made her FanNickname AscendedFanon but also gave her a speaking line. However, due to the voice actress thinking Derpy was male, she was given a deep voice which, given Derpy's role as TheDitz and the implications of her name, sounded like a SimpletonVoice. This resulted in complaints from MoralGuardians who claimed that "derpy" was pejorative and insensitive to people with disabilities. In order to avoid continued controversy, the episode became a MissingEpisode for a while, and when it returned to iTunes and [[Creator/DiscoveryFamily The Hub]], she was given a voice with less VocalDissonance and the line referring to her as "Derpy" was edited to take out the name (though The Hub's closed captioning wasn't updated to reflect the change). Many fans weren't happy, but episode writer Amy Keating Rogers later [[http://www.equestriadaily.com/2012/02/amy-keating-rogers-response-to-derpy.html explained why it had to happen]].
** It's worth mentioning that those who bought and downloaded the episode from iTunes early on (for example, those with a Season Pass) have the original version of the episode. Those who have the ''Friendship Express'' DVD also have the original version.
* In the original airing of the ''WesternAnimation/SupermanTheAnimatedSeries'' episode "Apokolips...Now! (Part 2)," Creator/StanLee, Comicbook/SpiderMan, the Comicbook/FantasticFour and Comicbook/NickFury could all be seen at Dan Turpin's funeral, with the cameos meant as an homage to the deceased Creator/JackKirby. For legal reasons, the cameos were all removed for the DVD release and subsequent airings.
* In the original cut of the 1933 Disney short, ''WesternAnimation/TheThreeLittlePigs'', TheBigBadWolf attempts to trick the pigs into letting him into the brick house by disguising himself as a stereotypical immigrant Jewish peddler, complete with skullcap, beard and exaggeratedly big nose. In 1948, the studio reanimated the scene so that the wolf was now disguised as a Fuller brush salesman. However, he still had a Yiddish accent. In subsequent prints, especially for TV, the audio was overdubbed to give him a [[SimpletonVoice generic "dumb guy" voice]].

* The original Ride/PiratesOfTheCaribbean ride at Ride/DisneyThemeParks was refurbished to include characters from the film adaptations, and even rerecorded dialogue for several of the ride's original characters referencing Jack Sparrow. [[BrokenBase Fan reaction was mixed]]. Many years prior to the movie, the ride was altered to give all the women being chased by the pirates plates full of food -- to tone down the implications of the scene by attempting to provide a G-rated motive for the pursuit (they're just trying to steal the food! And the women are trying to prevent them from stealing the food! that's all).
* It's been said, in fact, that one of Walt's motivations for building Disneyland in the first place was that he regretted not being able to change his movies after they were released, but a theme park has lots of opportunities for renovations. Whether he meant that recalling and re-editing his films would have been financially unfeasible when he had new movies that needed work on, or that ethically he just couldn't bring himself to do it, is uncertain.
* There are a few rather infamous images from the USSR featuring [[http://en.wikipedia.org/wiki/Censorship_of_images_in_the_Soviet_Union Stalin and others]]... then fewer and fewer 'others' as those people (or the nations they hailed from) fell out of favor, until only UsefulNotes/JosefStalin remained.
* When Orwell worked for the BBC he had trouble keeping up with shifting alliances. First the Soviets were neutral towards The Allies and against Germany & Japan (Second Sino-Japanese War), then neutral with Germany & Japan and against The Allies early in World War 2 (Molotov-Ribbentrop Non-Aggression Pact), then against Germany and neutral with Japan and allied with The Allies (Soviet-German War, Soviet-Japanese Non-Aggression Pact), and then against Japan for the last month of the war. And ''then'' the Soviets were against The Allies again as the Cold War sank in. Further complicating matters, every one of Germany's European allies (Italy, Romania, Hungary, Finland, etc) also ''fought on both sides''. Each and every time propaganda in the concerned countries had to change tack, sometimes drastically.
