I think there was talk about this a month or so ago, but ESPN formalized its relationship with Huffington Post for their Chicago coverage. Gives HuffPo some quality sports coverage for their Chicago site, and gives ESPN.com more distribution/awareness for their ESPNChicago.com content. Sounds like HuffPo Chicago will get content on ESPNChicago.com, too. Win-win.
UPDATE: I was thinking too locally, perhaps. The much bigger announcement is that ESPN got the rights to broadcast The Premiership (in the UK, no less) and La Liga.
