In 2007, Buffy's story continued on from season seven when Joss Whedon revived "Buffy the Vampire Slayer" as a comic book, again published by Dark Horse. Whedon differentiated these comics from previous "Buffy" literature, stating "We could do something and for once we could make it canon. We could make it officially what happened after the end of the show." The continuation series emulates the structure of a television series, with five "seasons" published between 2007 and 2018 and Whedon overseeing multiple writers in the role of "executive producer".
