Knight Rider was a wildly popular action show that ran from 1982 to 1986 on NBC. The show starred David Hasselhoff as Michael Knight. Each show started with the following narration: "Knight Rider, a shadowy flight into the dangerous world of a man who does not exist. Michael Knight, a young loner on a crusade to champion the cause of the innocent, the helpless, the powerless in a world of criminals who operate above the law." Knight would race around in his modified Trans Am, called KITT, while fighting crime.
The popularity of the show spawned a huge merchandising line, which included just about anything you can think of (TV trays, lunch boxes, board games, etc.). One of the more popular toys was a radio controlled version of KITT, and a KITT voice car which spoke (and came with a Michael Knight action figure). Of course there were die cast versions, like the Ertl Knight 2000, the Kenner Turbo Booster KITT car, and the Rough Rider 4X4 edition.
