Radio host Casey Kasem, known to generations as the voice of pop music countdown shows for close to four decades, passed away early Sunday morning at a hospital outside Seattle, according to a Facebook post by his daughter Kerri.
Kasem provided voices for a number of well-loved cartoon characters. His most celebrated role was Shaggy in various Scooby-Doo cartoons, starting with Scooby-Doo, Where Are You! in 1969. He was also the voice of Robin in Hanna-Barbera’s cartoons based on DC superheroes, and the voice of Mark in Battle of the Planets, the U.S. adaptation of the anime series Science Ninja Team Gatchaman.
