Saturday Night Live (abbreviated as SNL) is an American late-night live television sketch comedy and variety show created by Lorne Michaels and developed by Dick Ebersol. The show premiered on NBC on October 11, 1975, under the original title NBC's Saturday Night. The show's comedy sketches, which parody American culture and politics, are performed by a large and varying cast of repertory and newer cast members. Each episode is hosted by a celebrity guest, who usually delivers an opening monologue and performs in sketches with the cast, and features performances by a musical guest. An episode normally begins with a cold open sketch that ends with someone breaking character and proclaiming, 'Live from New York, it's Saturday Night!', beginning the show proper. Michaels left the series in 1980 to explore other opportunities. He was replaced by Jean Doumanian, who was replaced by Ebersol after a season of bad reviews.
