Fan Fiction - Fan fiction refers to the often elaborate, non-canonical stories that fans or users create using a certain medium or deliverance technology of that medium (such as a certain game, television show, anime film, et cetera). These stories are often not authorized by the creator of the source the fan fiction draws from (Jenkins 159), yet some fan fiction is embraced by original creators. Fan fiction can use characters already present in whatever world or story the new narrative is based on or create entirely new identies and shift the plot entirely. Fan fiction can be accompanied by fan made art, memes, inside jokes, and many other artifacts.
George Lucas and LucasArts established a policy for their filmmaking fans that excludes works seeking to "expand" upon the original work.
