In 1975, an Off-Broadway version of a Lampoon show led to his first television role as a cast member of the ABC variety show Saturday Night Live with Howard Cosell. That same season, another variety show titled NBC's Saturday Night premiered. Cosell's show lasted just one season, canceled in early 1976. After working in Los Angeles with the "guerrilla video" commune TVTV on several projects, Murray rose to prominence in 1976. He officially joined the cast of NBC's Saturday Night Live for the show's second season, following the departure of Chevy Chase. Murray was with SNL for three seasons from 1977 to 1980. A Rutland Weekend Television sketch Eric Idle brought for his appearance on SNL developed into the 1978 mockumentary All You Need Is Cash with Murray (alongside other SNL cast members) appearing as "Bill Murray the K", a send-up of New York radio host Murray the K, in a segment of the film that is a parody of the Maysles Brothers's documentary The Beatles: The First U. S. Visit. During the first few seasons of SNL, Murray engaged in a romantic relationship with fellow cast member Gilda Radner.
