Yahoo plans to ditch the Overture brand, according to ClickZ, adopting the prosaic Yahoo Search Marketing Solutions. Two years ago, Yahoo acquired the search engine advertising technology firm, which has since been the major engine for the company's growth. Yahoo plans to merge together the interfaces that advertisers use to manage both Overture search campaigns and Yahoo display advertising campaigns, presumably in hopes that some cross-pollination may occur. A new "Advertising Solutions Center" site will house both interfaces.
