About Cannon
William Conrad plays Frank Cannon, a former LAPD officer turned Los Angeles private detective, across 5 seasons on CBS from 1971 to 1976. The run opens with a two-hour pilot film from March 1971 and closes with the reunion film The Return of Frank Cannon from 1980.
Good to know
The Barnaby Jones premiere grew out of a planned Cannon episode, and the 1975 two-parter The Deadly Conspiracy crosses both shows, with part one airing as a Cannon season 5 episode. Release order matches story order so no separate chronology is listed.
