A popular American television show from the late 1990s through early 2000s, Buffy the Vampire Slayer has had a tremendous influence on popular culture that has attracted serious scholarly attention. Even the language used on the show has affected modern colloquial expressions.Susan Clerc, "Review of Slayer Slang: A Buffy the Vampire Slayer Lexicon," Journal of Popular Culture 38.2 (Nov 2004): 427–428. A noteworthy example of this pioneering is the fact that the first use on television of the phrase "to google" as a verb appeared on the show on October 15, 2002, in the fourth episode of the show's final season.
