Friday the 13th (franchise) (AxelGripp)

Friday the 13th is an American horror franchise that comprises twelve slasher films, a television series, novels, comic books, video games, and tie‑in merchandise. The franchise mainly focuses on the fictional character Jason Voorhees, who drowned as a boy at Camp Crystal Lake due to the negligence of the camp staff. Decades later, the lake is rumored to be "cursed" and is the setting for a series of mass murders. Jason is featured in all of the films, as either the killer or the motivation for the killings. The original film, created to cash in on the success of Halloween (1978), was written by Victor Miller and was produced and directed by Sean S. Cunningham. The films have grossed over $529 million at the box-office worldwide. It is the highest-grossing horror franchise in the world.

Although the films were not popular with critics, Friday the 13th is considered one of the most successful media franchises in America—not only for the success of the films, but also because of the extensive merchandising and repeated references to the series in popular culture. The franchise's popularity has generated a fanbase who have created their own Friday the 13th films, fashioned replica Jason Voorhees costumes, and tattooed their bodies with Friday the 13th artwork. Jason's hockey mask has become one of the most recognizable images in horror and popular culture.
