Clark, who started out as a TV announcer in Utica, New York, parlayed his "Bandstand" fame into a career as a producer and host of dozens of other shows, including ABC's annual "New Year's Rockin' Eve" telecast, which he launched in 1972.
His youthful good looks -- which he maintained into his 70s -- won him the nickname of "America's oldest teenager."
Clark suffered a stroke in December 2004 that forced him to sit out the Times Square show that year, but he returned 116;o co-host the program the following year.
With his clean-cut image and youthful appearance, he presided over more than three decades of pop music and dance trends as host of "American Bandstand," the first network TV show to feature rock 'n' roll.
He also produced such perennial TV events as the American Music Awards and the Golden Globes telecast..
