Retroactive continuity
[2] There are various motivations for applying retroactive continuity, including: Retcons are used by authors to increase their creative freedom, on the assumption that the changes are unimportant to the audience compared to the new story which can be told.More subtle and nondiegetic methods would be ignoring or expunging minor plot points to remove narrative elements the author doesn't have interest in writing."[6] A printed use of "retroactive continuity" referring to the altering of history in a fictional work is in All-Star Squadron #18 (February 1983) from DC Comics.All-Star Squadron was set during World War II on Earth-Two; as it was in the past of an alternate universe, all its events had repercussions on the contemporary continuity of the DC multiverse.Writer Roy Thomas responded, "we like to think that an enthusiastic ALL-STAR booster at one of Adam Malin's Creation Conventions in San Diego came up with the best name for it a few months back: 'Retroactive Continuity'.An early example of this type of retcon is the return of Sherlock Holmes, whom writer Arthur Conan Doyle apparently killed off in "The Final Problem" in 1893,[1][8][page needed] only to bring him back, in large part because of readers' responses, with "The Empty House" in 1903.Writers did this to offer a supposedly plausible reason for the major character of Bobby Ewing, who had died onscreen at the end of season eight, to be still alive when actor Patrick Duffy wanted to return to the series.
