Saturday Night Live began in 1975 when Lorne Michaels and Dick Ebersol filled an open late-night time slot with a live sketch comedy show featuring a rotating cast of 10 actors and a different celebrity host each week. Over the years, SNL has launched the careers of famous cast members like Chevy Chase, Dan Aykroyd, Will Ferrell, and Tina Fey and spawned successful movie franchises from popular sketch characters. It has won numerous awards including 21 Primetime Emmys and been recognized as one of the greatest TV shows of all time.
