New Streaming Music Service Already Has Millions In Sponsorship $ Committed

iTunes Radio hasn't event launched, but it's already lined up millions of dollars in sponsorship for its "Pandora Killer." Apple's new streaming music service, set to launch in September, will feature a blue chip line-up of launch partners including McDonald's, Nissan, Pepsi and Procter & Gamble. Only deep-pocketed partners need apply. The minimum buy-in? Advertising Age pegs that at a pricey $1 mil with deals running into the tens of millions for a 12 month run.
