History of Microsoft

Microsoft is a computer technology corporation founded on April 4, 1975, by Bill Gates and Paul Allen in Albuquerque, New Mexico, United States. It is best known for the Windows operating system, the Office productivity software suite, the Microsoft 365 subscription service, the Xbox video gaming brand, the Bing search engine, and the Azure cloud computing platform. In 1980, Microsoft formed a partnership with IBM to bundle Microsoft's operating system with IBM computers; with that deal, IBM paid Microsoft a royalty for every sale. In 1985, IBM requested Microsoft to develop a new operating system for their computers called OS/2. Microsoft produced that operating system, but also continued to sell their own alternative, which proved to be in direct competition with OS/2. Windows eventually overshadowed OS/2 in terms of sales. When Microsoft launched several Windows versions in the 1990s, they had captured over 90% market share of the world's personal computers. As of June 30, 2015, Microsoft has a global annual revenue of US$86.83 billion (~$112 billion in 2024) and 128,076 employees worldwide.
