Saturday Night Live with Howard Cosell was a program that ran on ABC from September 1975 to January 1976, hosted by Howard Cosell.

A program called NBC's Saturday Night debuted the same year. Once Cosell's show was cancelled, the NBC show renamed itself Saturday Night Live.NBC.com > Saturday Night Live

The Cosell show featured Bill Murray, Brian Doyle-Murray, and Christopher Guest as regular comedy performers, dubbed "The Prime Time Players." In response, the NBC show called its regular performers "the Not-Ready-For-Prime-Time Players". Ironically, all three of the original Prime Time Players eventually joined the NBC show. Old TV Tickets
