Two internet search giants announce an advertising alliance. Yahoo announces its team up with Google, the company that dethroned the Internet firm in the world of Internet search. Google will use its online ad targeting skills and large stocks of ads to present Yahoo! website users with relevant marketing messages, generating revenue. Yahoo! says, "By adding Google to our list of world-class contextual ads partners, we'll be able to expand our network, which means we can serve users with ads that are even more meaningful." The move also raises the possibility of Yahoo! turning to Google to power Internet searches at its website, once freed from its current deal to use Microsoft's Bing service.
