December 11, 1980 –

Hawaiian shirts and free mustache rides abound when Magnum PI, starring Tom Selleck, premiered on CBS-TV on this date.
The show was set in Hawaii partly because CBS did not want to close its Hawaii production offices when Hawaii Five-O ceased production in 1980. This show started production that year and contained occasional references to Steve McGarrett and “Five-O“, although McGarrett was never shown.
