It’s official. Yahoo has thrown in the towel. Microsoft and Yahoo have been talking about a search partnership for a while – talks that intensified after merger talks fell through, and now they see eye to eye on a 10-year partnership. MS will bring the Bing-Bing in the form of search, and Yahoo will bring the ching-ching in the form of advertising. The partnership makes them a formidable search competitor to Google’s 800-pound gorilla. source
