New York, Austin, Los Angeles among NPR affliates
As anticipated, ESPN and a collection of local National Public Radio affiliates have been added to Apple's iTunes Radio service. Both are live streams of their broadcast counterparts, and in some cases use custom art for individual shows. Some of the NPR affiliates include ones in Austin, Chicago, Los Angeles, New York, St. Louis, and Washington DC.
NPR has actually had a presence on iTunes Radio since March, but not in the form of local stations. Even with the latest additions, live content is scarce on the service; it's still built primarily around Pandora-style streaming of iTunes content.
