Adam-12 is an American television drama which originally aired from September 21, 1968 to August 30, 1975 on NBC for 175 episodes. The show was produced by Jack Webb's Mark VII Limited, which also produced Dragnet and Emergency!. The series was nominally considered a spin-off of Webb's Dragnet 1967 70, and the Reed and Malloy characters appeared on episodes of the parent program (though the actors did appear as different characters on some of the Dragnet episodes).
