Hawaii Five-O (with a capital letter "O" as the last character in the title) is an American police procedural drama series produced by CBS Productions and created by Leonard Freeman (not to be confused with Hawaii 5-0, with a numeral zero as the last character in the title). Set in Hawaii, the show originally aired for 12 seasons on CBS from September 20, 1968, to April 8, 1980, and continues in reruns. At the airing of its last episode, it was the longest-running police drama in American television history and the last scripted primetime show that debuted in the 1960s to leave the air. The show starred Jack Lord as Detective Captain Stephen "Steve" McGarrett, the head of a fictional state police task force in Hawaii. The theme music composed by Morton Stevens became especially popular. Many episodes in the series would end with McGarrett's catchphrase, "Book 'em!" Overview The CBS television network produced Hawaii Five-O, which aired from September 20, 1968, to April 5, 1980. The program continues to be broadcast in syndication worldwide. Created by Leonard Freeman, Hawaii Five-O was shot on location in Honolulu, Hawaii, and throughout the island of Oahu and other Hawaiian islands with occasional filming in locales such as Los Angeles, Singapore, and Hong Kong. The show centers on a fictional state police force led by former US naval officer Steve McGarrett (played by Jack Lord), a detective captain, who is appointed by the Governor, Paul Jameson. In the show, McGarrett oversees state police officers – the young Danny "Danno" Williams, veteran Chin Ho Kelly, and streetwise Kono Kalakaua for seasons one through four. Honolulu Police Department Officer Duke Lukela joined the team as a regular, as did Ben Kokua, who replaced Kono beginning with season five. Occasionally, McGarrett's Five-O team is assisted by other officers as needed: Det. Frank Kamana (Douglas Mossman), P.O. Sandi Wells (Amanda McBroom), medical examiner Doc Bergman (Al Eben), forensic specialist Che Fong (Harry Endo), and a secretary. The first secretary was May, then Jenny, and later Malia, Lani and Luana. The title of the show refers to Hawaii's status as the 50th US state; at the time of its premiere, Hawaii had officially been a U.S. state for only nine years. The Five-O team consists of three to five members (small for a real state police unit), and is portrayed as occupying a suite of offices in the
