The man listed in Guinness World Records as the "most watched TV star in the world" got his start on daytime television. Between 1975 and 1982, Hasselhoff could be seen on The Young and the Restless as Dr. Snapper Foster, who was put through college by his poor mother and manicurist sister (Jill Abbott, who is still on the show). After seven years, Hasselhoff left daytime TV without knowing what would come next. But he didn't have to wonder for long -- NBC President Brandon Tartikoff asked him to play the lead (opposite a talking car) in a new show called Knight Rider. By 1989, the phenomenon known as Baywatch hit the airwaves with Hasselhoff at the helm as lead actor and executive producer.
