Federated Media loses another client to an acquisition

High-Def Digest, a video enthusiast site with more traffic than Boing Boing, has been sold to Internet Brands, a domain-name speculator turned online-advertising network. That's bad news for John Battelle's Federated Media network, which up until now has repped the site; with Sphere's sale to AOL, it's the second acquisition this month to thin Federated's client list.
