Adam-12

Adam-12 was a television show that ran from 1968 to 1975 on NBC. The show was centered around the daily activities of a pair of Los Angeles police officers, Pete Malloy (played by Martin Milner) and Jim Reed (Kent McCord). It included Sergeant William "Mac" MacDonald (played by William Boyett). The show was produced by Jack Webb, who also helped create Dragnet and Emergency!. The series was considered a spin-off of Webb's Dragnet 1967, and the Reed and Malloy characters appeared on episodes of the parent program.
The officers worked out of the Central Division of the LAPD. The show used situations from realy LAPD case files. . The title of the show is derived from the radio car unit number of the officers, 1(for Central Division, though Rampart Division was actually used as the location), A(dam) to designate it as a two man patrol, and 12 to designate their patrol area.
As with Dragnet, Adam-12 episodes were based on incidents in the actual case files from the LAPD. At the end of each episode the "names have been changed..." statement was shown (but not narrated) at the start of the ending credits.
