Saturday Night Live [SEP] Introduction
Saturday Night Live (also known simply 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 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 as with featured 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!", properly beginning the show.
