Yahoo!, Microsoft ink Web-search agreement

Yahoo! and Microsoft announced that they have finalised the details of their planned internet search and advertising partnership. The companies hope to implement the deal next year with the approval of the anti-trust regulators.
Yahoo! and Microsoft had originally planned to complete their agreement by October 27, but extended talks, "given the complex nature of the transaction", delayed the completion. The plan to ink a 10-year web-search and advertising pact was unveiled in july and promises to set the stage for a Yahoo!-Microsoft offensive against Google, the king of the lucrative search and advertising market.
Under the no-cash deal, Yahoo! will use Microsoft's new Bing search engine on its own sites while Yahoo! will provide the exclusive global sales force for premium search advertisers.
