Stick a fork in it. The proposed deal for Google and Yahoo! to join forces running Google ads on Yahoo web sites is officially dead.
This deal was originally announced months ago (June to be exact). Since then there's been much queasiness at the idea of the two search engine monoliths partnering up. I believe the words "possible anti-trust lawsuit" have been used. Google pulled the plug announcing it on their public policy blog (yes, they have a public policy blog).
Meantime, Yahoo! is apparantly not happy. They really needed this deal, which was announced on the heels of Microsoft's failed hostile takeover bid earlier this year. Microsoft's failed overtures left Yahoo! stock in the tank. This deal was supposed to bring in $800 million in added revenue in its first year. So ouch!
