Mannix is a detective TV show created by Richard Levinson and William Link, and produced by Bruce Geller (who also created the espionage series Mission: Impossible). It ran from 1967 to 1975 on the channel CBS alongside M:I.
Mannix followed the life of Los Angeles private investigator Joseph "Joe" Mannix, played by Mike Connors, and his African-American secretary, Peggy Fair (played by Gail Fisher). Mannix is of Armenian descent (like Connors himself), and is proficient in most athletics, including being a black belt in Karate, a decent skier, and an excellent pool player. He is also a veteran of the Korean War. In Season 1, he works for detective firm Intertect. Starting in Season 2, he lives and works in his own office at 17 Paseo Verde, West LA. He carries a Walther PP in Season 1, which can be seen in the intro, but starts to carry a Colt Detective Special from Season 2 onwards.
The show won the "Golden Globe Award for Best Television Series – Drama" in 1971, which was late Season 4 and early Season 5. Mike Connors himself also won an award for his portrayal of Mannix, the 1969 Golden Globe Awards (for which he was nominated six consecutive times) and 4 straight Emmy nominations from 1970 to 1973. Mannix, the series itself, was twice nominated for the Emmy Award for Best Dramatic Series. In 1972, writer Mann Rubin won an Edgar Award from the Mystery Writers of America for the episode "A Step in Time" (S5E03).
