64. Ryan Seacrest
Ryan Seacrest Media
Set Ryan Seacrest’s “American Idol” duties aside for a moment: It’s really just the capstone to an impressive entertainment industry power base. For starters, there’s his syndicated daily four-hour Clear Channel radio show “On Air,” heard in more than 150 markets. Then there’s his eight-plus-year run as host of “American Top 40″ and a production company at NBC Universal. Potentially most significant to his power base, however, is Seacrest’s new alliance with Mark Cuban, Creative Artists Agency and AEG to reshape HDNet into a pop network. HDNet is slated to become AXS TV this summer, and it aims to leverage CAA’s acts, AEG’s venues and Seacrest’s connections and production capabilities. The network will cater to pop culture and entertainment enthusiasts; Seacrest, through Ryan Seacrest Media, is an investor but won’t be an on-air talent. Satellite TV company Dish and the network will launch AXS Headliner Club, an online audition site for musicians looking to perform at AEG venues.
