Google Inc. Chief Executive Eric Schmidt called Yahoo Inc. CEO Jerry Yang to offer his company's help in any effort to thwart Microsoft Corp.'s unsolicited $44.6 billion bid for Yahoo, say people familiar with the matter.

Microsoft wants to acquire Yahoo search and is seeking partners, including Time Warner and News Corp., to take over the rest of Yahoo's business

Option investors bet heavily on Monday that Yahoo might strike a deal of some sort with Microsoft Corp, spurred on in part by pressure from activist shareholder Carl Icahn.

Microsoft has proposed an alternative deal for Yahoo, a complex transaction that would include just buying Yahoo's search business, rather than a full buyout, a person familiar with the discussions said on Monday.

Microsoft Corp. today sent the following letter to the Yahoo! Inc. Board of Directors:

Just a few hours after Yahoo! rejected Microsoft's $44.6bn purchase offer, the Redmond-based software giant has responded, reiterating that it "reserves the right to pursue all necessary steps to ensure that Yahoo!'s shareholders are provided with the opportunity to realize the value inherent in our proposal."

We have seen extensive press coverage of Microsoft's pursuit of Yahoo over the last few months, including notably excellent coverage from Silicon Alley Insider and the Wall Street Journal. However, I have not seen a detailed analysis of how a full hostile takeover might play out -- the kind of analysis that you would be receiving if you were a Microsoft or Yahoo board member.

SEATTLE–Microsoft Corp. has withdrawn its $42.3-billion (U.S.) bid to buy Yahoo Inc., scrapping an attempt to snap up the tarnished Internet icon in hopes of toppling online search and advertising leader Google Inc

After several months of discussion and speculation, the Microsoft-Yahoo buyout deal is apparently off. At least, that's what both Microsoft and Yahoo announced over the weekend. There is some speculation that Microsoft CEO Steve Ballmer made his announcement in order to topple Yahoo's share price, in order to make another offer at a lower price.

When Yahoo acquired Zimbra in September 2007, some Zimbra backers worried Yahoo would mismanage the open source email asset. Fast forward to the present, and some Zimbra proponents have gone from concern to outright panic over Microsoft’s bid to acquire Yahoo (and, by attachment, Zimbra).
