Microsoft is not happy with owning 99% of the PC desktop market. It wants to own all of the internet search too. Microsoft made unofficial approaches to take over Yahoo's search technology. Only to be rebuffed by Yahoo CEO, Terry Semel.

Semel said: "My impartial advice to Microsoft is that you have no chance. The search business has been formed."

The thought of another quasi-monopoly on internet search does not bare thinking about.
