LOS ANGELES (AP) --

Dick Clark, the ever-youthful television host and tireless entrepreneur who helped bring rock `n' roll into the mainstream on "American Bandstand," and later produced and hosted a vast range of programming from game shows to the year-end countdown from Times Square on "New Year's Rockin' Eve," has died. He was 82.

Spokesman Paul Shefrin said Clark had a heart attack Wednesday morning at Saint John's hospital in Santa Monica, where he had gone the day before for an outpatient procedure.

Clark had continued performing even after he suffered a stroke in 2004 that affected his ability to speak and walk.
