Is Apple a real risk to the ad revenue model for Pandora? Pandora outperforms AppleApple is no threat Apple’s iRadio is not a threat for Pandora, since the service will only work in Apple products. Pandora has an established customer base who already invested time in building music lists. Customers enjoy limited commercials and would need to acquire an Apple product to use the iRadio service. The high usage of Pandora is like a gold mine for advertisers.

If the interface is as good as other Apple products, which is very likely, then Pandora will lose many users after the iRadio launch.
