In 1992, the franchise expanded to a television series with "The Young Indiana Jones Chronicles", portraying the character in his childhood and youth, and including adventures with his father. Marvel Comics began publishing "The Further Adventures of Indiana Jones" in 1983, and Dark Horse Comics gained the comic book rights to the character in 1991. Novelizations of the films have been published, as well as many novels with original adventures, including a series of German novels by Wolfgang Hohlbein, twelve novels set before the films published by Bantam Books, and a series set during the character's childhood inspired by the television show. Numerous "Indiana Jones" video games have been released since 1982.
