What do today's kids really know about David Hasselhoff? They know him as a leather-jacket-wearing judge on America's Got Talent, as the German dodgeball coach in Dodgeball and as a hamburger-eating drunk on the Internet. But do they know what he did? What he accomplished? I'm not talking about the Baywatch franchise -- no, not even Baywatch Nights. I'm talkin' about Knight Rider. It was just a simple show about a guy and his car, solvin' crimes and jumping through moving trains, but Hasselhoff elevated the material, creating a hit, spawning numerous remakes and forging an American icon. Has he been given a medal yet? He should be. To celebrate the return of the Hoff to America's Got Talent, we thought we'd take a look at the rich history of Knight Rider, from 1982 to today.
