ESPN has announced that its PodCenter service will be available on the iPhone from now, and “exclusive content for iPhone users is also in the works”—although what that content will be isn’t described. The deal covers 35 podcasts with 15-20 sponsors, and podcasts to the iPhone will have the unique feature of displaying the advertisers’ logo on the handset screen during the audio ads, reports Ad Age. Marc Horine, ESPN’s VP-digital partnerships and radio, said that he was working with Verizon to expand the content on that telco as well, but: “It’s not as easy to deliver podcasts through mobile devices right now,” he said. “IPhone allows us because the Safari internet browser takes you to the special player. Most [phones] don’t have the functionality the iPhone has.” It seems like a relatively simple thing—I don’t know whether he’s refering to most handsets on the market or most high-end handsets.
