Dick Clark, who hosted American Bandstand and then New Year's Rockin' Eve, died this morning in Los Angeles from a massive heart attack. He was 82 years old, but for years his nickname was "America's Oldest Teenager." Dick began as a Philadelphia radio DJ in 1952. Not long after, he began hosting a local TV show called Bandstand, which featured teenagers dancing to current music hits. When ABC picked up the show for national coverage, it was renamed American Bandstand and big name guests of the time such as Elvis, Ricky Nelson, Fabian and Frankie Avalon were invited. In 1963, Dick and the show moved to Los Angeles, where he formed Dick Clark Productions. The company produced other shows as well and in 1972, Dick began hosting an annual New Year's Eve special from Times Square in New York City. Regis Philbin filled in when Dick suffered a stroke in 2004 that left him partially paralyzed. Despite having trouble speaking, he returned the following year and in the past few years, had shared the hosting duties with Ryan Seacrest. Dick is survived by his third wife Kari and his three children.
