Charlie O'Donnell, the announcer whose voice has opened 'Wheel of Fortune' for decades, has died. He was 78. Agent Fred Wostbrock said Monday that O'Donnell -- the voice of the game show even before hosts Pat Sajak and Vanna White appeared -- died late Sunday at his Los Angeles home. The cause was unclear.

O'Donnell was a popular radio DJ in New York before starting his television career in Philadelphia with Dick Clark on 'American Bandstand.'

He also served as announcer for Oscar and Emmy telecasts and other game shows, including 'The Newlywed Game.'
