Charlie's Angels is an American crime drama television series that aired on ABC from September 22, 1976, to June 24, 1981, airing for five seasons consisting of 115 episodes. It was created by Ivan Goff and Ben Roberts and was produced by Spelling-Goldberg Productions. The show follows the crime-fighting adventures of three women working at a private detective agency in Los Angeles, California, and originally starred Kate Jackson, Farrah Fawcett (billed as Farrah Fawcett-Majors), and Jaclyn Smith in the leading roles and John Forsythe providing the voice of their boss, the unseen Charlie Townsend, who directed the crime-fighting operations of the "Angels" over a speakerphone. There were a few casting changes: after the departure of Fawcett, Cheryl Ladd joined; after Jackson departed, Shelley Hack joined, and she was subsequently replaced by Tanya Roberts.

Plot

In the initial concept, Sabrina Duncan, Jill Munroe, and Kelly Garrett have graduated from the police academy in Los Angeles, California. Despite proving their capability during training, all three have subsequently been assigned to be a meter maid, office worker, and crossing guard, respectively. Dissatisfied with these jobs, they are recruited to work for the Charles Townsend Agency as private investigators. All of this is explained in the opening credit sequence; neither the pilot film nor subsequent series ever actually depicted an "origin story" as they are seen to have been working as investigators for some time as of the start of the pilot.
