'The Tonight Show' is a U.S. talk and variety show on NBC. Originating on network television in 1954, there have been a number of versions of the show with four primary hosts. The format has varied with each host's style, but has always consisted mainly of celebrity interviews, humor, and music.


The hosts include:

Steve Allen - 1954 to 1957

Jack Paar - 1957 to 1962

Johnny Carson - 1962 to 1992

Jay Leno - 1992 to current

Ernie Kovacs briefly acted as co-host two nights a week near the end of the Steve Allen years, and there have been numerous 'guest hosts' throughout the show's history.
