THR's 2012 Digital Power 50

"Plenty of websites post celebrity photos, but the celebrities don't get any of the benefits," says Ellis, 40. That's why he created WhoSay, which hosts free, easy-to-update online content for invite-only celebs like Tom Hanks, Enrique Iglesias, Stan Lee, Steve Martin, Gwyneth Paltrow and Rihanna. WhoSay stars collectively boast 570 million fans across Twitter, Facebook, MySpace and other platforms, and their pages draw 10 million unique users each month. All those eyeballs, he says, will be worth money one day through endorsements, advertising and e-commerce, and WhoSay will split the revenue with its celebrity partners.
