Yahoo! co-founder Jerry Yang's turn as CEO will likely be remembered for his efforts to keep the company independent by staving off a takeover bid from Microsoft. But Yang is facing a shareholder revolt led by investor Carl Icahn, and possible antitrust inquiries about a new search advertising deal with rival Google. Yahoo! President Sue Decker said Yang "has an unwavering vision of where he wants to take Yahoo! and an unwavering passion and commitment and energy to get there." However, many in the tech and financial sectors believe that Yang acted on emotion in rejecting Microsoft's bid for Yahoo!, rather than in the best interests of the company and its shareholders.
