ESPN is launching a local podcasting network. Sounds like they’re starting with shows from their five owned-and-operated stations while inviting affiliates to be part of the podcast network.

For more than a year, ESPN has been offering about 20 podcasts of national ESPN programming through PodCenter and selling advertisers two spots, one 15-second spot rolling prior to the content and a 30-second post-content spot. The new local podcasting network provides advertisers the opportunity to buy a local podcasting network or target individual markets or regions. Participating affiliates will get a share of the network revenue sold.

The local stations could (and may be) podcasting on their own but I have to believe this approach (whole greater than sum of parts) makes sense. Once clearance becomes a non-issue, there might be an explosion of such podcast networks. [Mediaweek via Radio and Records]
