What put it there?
The television series Magnum, P.I., which began airing on CBS in December of 1980.
The show’s lead character, former Naval Intelligence officer Thomas Magnum (played by Tom Selleck), was a “cocky and chivalrous” private investigator who lived on Oahu (and frequently wore Hawaiian shirts).
For his portrayal of Magnum, Selleck was nominated for the Emmy Award for Outstanding Lead Actor in a Drama Series five times, winning once (in 1984).
The surname Magnum derives from the personal name Magnus, which comes directly from the Latin adjective magnus, meaning “great.”
