The Tomorrow Show was a late-night talk show that followed The Tonight Show with Johnny Carson. The Tomorrow Show aired Mondays through Thursdays (or, to be more exact, early morning Tuesdays through Fridays).
The Tomorrow Show started as a 60-minute series. It expanded to 90 minutes in September 1980. A month later, Rona Barrett joined the series. She eventually became the West Coast co-host and the series was re-titled Tomorrow Coast-To-Coast. Rona Barrett stayed with the show through Spring 1981.
In February 1982, NBC replaced Tomorrow Coast-To-Coast with Late Night with David Letterman.
