It is official: two of the World Wide Web’s largest search entities Yahoo! and Google are set to rock the world with its future partnership. They will cooperate after agreeing on a search advertising deal. So shaken were the public and other investors that Yahoo Inc.’s shares plummeted down 3 percent in June 2008 shortly after the merger is announced. As if that is not enough, it further dropped 16 percent after Yahoo Inc. refused to foster ties with another Internet giant, Microsoft. Investors are concerned that Yahoo! will eventually lose out to Google but its president assures them that they will profit via less common search terms.
