Ive seen what look like Five-O episodes run under the title McGarrett. What gives?
CBS had a late-night ‘series’ to compete against the talk shows (Johnny Carson in particular), which consisted of reruns of their best shows such as Five-O, Magnum, P.I. and others. They even bought an additional fourth season of the cancelled ABC series T. J. Hooker for this gig. They selected episodes from the twelfth season of Five-O to run in this slot, and changed the title to McGarrett. As to WHY they changed the name, who knows what evil lurks in the mind of TV network execs!
