From 2006 to 2008, Microsoft expresses interest in buying or merging with Yahoo. On Feb. 1, 2008, Microsoft makes an unsolicited $44.6 billion bid for Yahoo, but the offer is rebuffed. Yahoo also considers other mergers, including one with Google, but decides to go it alone. Investor Carl Icahn rips Yahoo's decision and launches a proxy fight to replace the company's board. In July 2008, the company agrees to appoint Icahn and two allies to an expanded board.
