Kasem was the host of the "American Top 40" radio program for over three decades, and he voiced iconic cartoon characters including Shaggy on "Scooby-Doo" and Robin on "Super Friends."
In his later years, Kasem suffered from advanced Parkinson's Disease and dementia, and his family's bizarre disputes made headlines across the country.
Glenn Beck paid tribute to Kasem last month, reflecting on the impact Kasem had had on Beck's own career.
