George Carlin

George Carlin hosted the first episode of the show we now know as Saturday Night Live. When the first show aired on October 11, 1975 with George Carlin as its host, it was called NBC's Saturday Night because ABC featured a program at the same time titled Saturday Night Live with Howard Cosell. After ABC cancelled the Cosell program in 1976, the NBC program changed its name to Saturday Night Live on March 26, 1977 (and subsequently picked up Bill Murray from Cosell's show).
