An American horror anthology TV franchise, running sporadically on TV since 1959 and since branched out into other different mediums, including radio dramas, film, and pinball.
Created and originally presented by Rod Serling, the original 1959-1964 run is considered to be one of the greatest television shows of all time. Notable episodes include "To Serve Man (1962), "It's a Good Life" (1961), and "The Monsters are Due On Maple Street" (1960). Each episode had a twist ending and presented a moral to the audience.
