Bill Gates bought DOS from Digital Research without telling them about
the IBM deal and most of his "innovation" since then was also from
simply buying a better package from a competitor.
His biggest stroke of luck was that IBM had just fended off the DoJ
anti trust suit that had gone on for a decade and IBM was not in a
position to buy DOS from him outright and start that process all over
again.



Gates did not buy DOS from DR. They were compeating companies. DR sold
their system for about $ 150 or $ 250 and MS for $ 49.
People went to the less expensive system.

Gates bought the operating system from another company and licensed the
use to IBM. It was a very smart move for MS. They do not really sell
their products, but license the use of them.

It is a derivative of CPM that was from DR.
They ended up having to pay to avoid being sued the way I understand
it.
