eBay To Test TV Ad System; Not Google

MediaPost reports that eBay was awarded the bid to test an online auction system for buying and selling TV ads. The Association of National Advertisers announced today that they "will work with its membership to explore opportunities around the development of an Online Media Exchange." Those on the testing committee are listed here. Forbes has a nice recent article from last week on the possibilities of this happening. What happened to Google providing this system? I guess eBay was more qualified.
