jerryyang4.jpgYahoo's last-ditch effort to fend off Microsoft's takeover bid: A deal to test Google's (GOOG) ads on some of its search pages. Microsoft has predictably slammed the deal, saying that any Yahoo-Google ad tie-up would make the Web ad market less competitive than its own deal for Yahoo.
"Any definitive agreement between Yahoo and Google would consolidate over 90% of the search advertising market in Google's hands," Microsoft said in a statement. "Our proposal remains the only alternative put forward that offers Yahoo! shareholders full and fair value for their shares, gives every shareholder a vote on the future of the company, and enhances choice for content creators, advertisers, and consumers."
