"On paper, Magnum, P.I. reads like your everyday action show," says Shawn Van Horn of Selleck's 1980-1988 CBS action series. But, says Van Horn, "it’s the locale and Selleck’s charismatic character that breaks the series free from its '80s detective show chains. Like Hawaii Five-O, Magnum, P.I. is known for its great intro. Both have very distinctive songs, Magnum, P.I. with that unforgettable guitar riff, interspersed with shots of Magnum and crew in the midst of their adventures, Oahu in the background, waves crashing on the beach. In detective shows of TV’s past, most were centered in one location that audiences were accustomed to. Starsky & Hutch, CHiPs, Adam-12, The Rockford Files, and Charlie’s Angels were all set in southern California. Kojak, McCloud, and Baretta fought crime on the opposite shores of New York City. By the 80s, action shows began to expand their territory. The A-Team and MacGyver, for example, were world travelers, leaving behind the stuffy offices and overused backdrops. Magnum, P.I. stayed put, but also became different by doing so."
