Description: The Steve Allen Show was the first in a series of prime time spin-offs from The Tonight Show, all of which were named after the host: Jack Paar (1962 to 1965) and Jay Leno (2009 to 2010) would follow in Allen's footsteps. The show launched the careers of cast members Don Knotts, Tom Poston, Louis Nye, Pat Harrington Jr., Tim Conway, Bill Dana, and, near the end of its run, Jim Nabors.
