Yahoo Inc. (NDAQ: YHOO) shares dropped off a cliff today after the search company shunned Microsoft Corporation (NYSE: MSFT) completely in favor of a deal with Google Inc. (NDAQ: GOOG) instead. Management may have finally found a way out of the situation, but shareholders clearly disapproved of the new deal. Shares plummeted nearly 5 percent on the news as a Microsoft deal is now completely out of the picture.

The only hope remaining for some shareholders is Carl Icahn's continued involvement. The activist shareholder had been pushing for a deal with Microsoft and even nominated his own directors to the board in order to effect change. The aging investor isn't known for giving up either, so it should be a fight until the end. Investors don't have to look back too far to see that fact- he had to try twice to effect change in Motorola!

However, the fact remains that most proxy contests end up failing. Moreover, Microsoft has not indicated that it would still be interested in a deal even if Icahn did take over the company. The only thing that is for certain is that the Google deal would be voided if Icahn does win control over the search giant. This fact could put a strain on his popularity with institutional investors as a loss of a Google and Microsoft deal would put Yahoo back to step 1.

In the end, it is no secret that Yahoo needs to change something in order to get itself out of its current lull. Management believes that a partnership with Google would help increase its revenues. Shareholders believe that a sale to Microsoft represents the bet immediate solution. Overall, it looks like Google is the only clear winner as it has now secured a deal with Yahoo while also eliminating any deal with Microsoft that could boost its competition.
