Saturday Night Live (SNL) is a groundbreaking live sketch comedy variety show created by Lorne Michaels and Dick Ebersol, which premiered on NBC on October 11, 1975, hosted by George Carlin. Each episode features a celebrity host and a musical guest, famously opening with a cold sketch that ends with the phrase "Live from New York, it's Saturday Night!" The show, broadcast from Studio 8H at Rockefeller Center, has aired over 1,008 episodes, making it one of the longest-running network programs in U.S. history. After a turbulent period in the early 1980s, Michaels returned in 1985 and has served as showrunner ever since, cementing the series as a launchpad for stars like Chevy Chase and John Belushi. Its success has spawned major feature films such as The Blues Brothers (1980), Wayne's World (1992), and A Night at the Roxbury (1998). With 84 Primetime Emmy Awards and over 305 Emmy nominations—the most ever for a TV program—SNL has been honored with 3 Peabody Awards and is widely ranked among the greatest TV shows of all time.
