William Gates III called by the whole world as Bill Gates is the richest man in the world.

He is the Czar of the software empire and was mainly responsible for bringing in the technology revolution the world is witnessing today.

This college drop out sensed a great business opportunity when IBM wanted to sell their personal computers but did not have an operating system for it. Microsoft bought the rights to QDOS for $50,000 from Seattle Computer Products and modified it for use on IBM machines. Bill Gates licensed the operating system as MS DOS and made a fortune selling it. The successors of the MS DOS were the Windows series which made personal computers a house hold name. He went on to build his company, Microsoft, and the rest is history.

Today the net fortune of this Billionaire is estimated at $ 50 billions. It is some amount to own at the age of fifty.
