Microsoft is searching for an answer to a tough problem.
That problem is Live.com, which many may not even know is Microsoft's search engine.
While it's not technically bad, it's far from being the leading search engine - handling less than 10 percent of all searches in the United States.
That means it's far from the billions in online ad revenue that have turned Google into a internet powerhouse that is now being looked at by federal regulators for having too much control over the world's information and advertising. And as browsers are on the way to becoming more important than the operating system they ride on, Microsoft needs to find a way to be something more than a perpetual online bronze winner. Or else it could become as irrelevant as MS-DOS.
