In a keynote presentation at the Interactive Advertising Bureau’s Ecosystem 2.0 conference last month, new IAB chairperson Wenda Harris Millard sparked a new round of questioning over the rise of ad networks—admonishing fellow media executives not to sell ad inventory like pork bellies, i.e., to the lowest bidder. Rather than a declaration of war against remnant ad nets, Millard, president of media for Martha Stewart Living Omnimedia (NYSE: MSO), urged web publishers to educate themselves as well as marketers and agencies about the best ways to use online advertising: “We must educate one and all about the value our digital offerings provide marketers and not trade our advertising space like pork bellies.” You can watch the speech here courtesy of IAB.
