The Muppet Show is a family-oriented comedy-variety television series that was produced by puppeteer Jim Henson and features The Muppets. After two pilot episodes produced in 1974 and 1975 failed to get the attention of network executives in the United States, Lew Grade approached Henson to produce the programme in the United Kingdom for ATV. The show lasted for five series consisting of 120 episodes which were first broadcast in Britain between 5 September 1976 and 15 March 1981. Kermit the Frog stars as a showrunner who tries to keep control of the antics of the other Muppet characters, as well as keep the guest stars happy. The show was known for outrageous physical slapstick, sometimes absurdist comedy and humorous parodies. Each episode also featured a human guest star. As the show's popularity rose, many celebrities were eager to perform with the Muppets on television and in film.
