WEB 2.0 SUMMIT — At a panel discussion about making money in online video, Federated Media VP of sales Chas Edwards said he'd pulled checks "from a million dollars down to $10,000" for video ads on Federated's network, which includes the popular shows Diggnation and Ask a Ninja. The burning question: Who paid a million bucks to Federated, run by Web 2.0 conference co-chief John Battelle, and for what? We were unable to tackle any of Federated's execs at the jam-packed conference Wednesday. Somebody get Edwards or jbat to spill the details, and send it to us. Otherwise we'll wonder if Edwards wasn't actually referring to Microsoft's non-video advertorial deal for which Federated bloggers wrote ad copy. Why? Because Edwards also said the biggest dollars come from selling "host endorsements" rather than separate advertiser-produced spots.
