Product Divisions

To be more precise in tracking performance of each unit and delegating responsibility, Microsoft reorganized into seven core business groups — each an independent financial entity — in April 2002. Later, on September 20, 2005, Microsoft announced a rationalization of its original seven business groups into the three core divisions that exist today: the Windows Client, MSN and Server and Tool groups were merged into the Microsoft Platform Products & Services Division; the Information Worker and Microsoft Business Solutions groups were merged into the Microsoft Business Division; and the Mobile and Embedded Devices and Home and Entertainment groups were merged into the Microsoft Entertainment and Devices Division.
