Under new CEO John Donahoe, eBay is moving to take its affiliate marketing in-house, a tipster tells us. The auction giant could dump ValueClick's Commission Junction, which currently pays website publishers to direct bidders to eBay's stores, for its own eBay Partner Network. The eBay website is already active, with what appears to be a login for beta testers. eBay Partner Network is also the name of a recently formed eBay subsidiary, according to an SEC filing. Amazon.com has long had its own affiliate-marketing subsidiary, which has turned into a venture to provide all kinds of services to startups. By farming out the work, eBay has lost both a cut of its sales and a chance to play in a field that's a fast-growing part of online advertising.
