Saturday Night Live (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 often parody contemporary 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 the opening monologue and performs in sketches with the cast. There is also a musical guest, who performs one or two songs.
