History of Microsoft

Microsoft is a multinational computer technology corporation. The History of Microsoft began on April 4, 1975, when it was founded by Bill Gates and Paul Allen in Albuquerque. Its current best selling products are the Microsoft Windows operating system and the Microsoft Office suite of productivity software.

Starting in 1980, Microsoft formed an important partnership with IBM which allowed them to bundle Microsoft's operating system with computers that they sold, paying Microsoft a royalty for every sale. In 1985, IBM requested that Microsoft write a new operating system for their computers called the OS/2; Microsoft wrote the operating system, but also continued to sell their own version of it, which was in direct competition with the OS/2. The Microsoft version eventually overshadowed the OS/2 in terms of sales. When Microsoft launched several versions of Microsoft Windows in the 1990s, they had captured over 90% market share of the world's personal computers.

The company has now become largely successful. As of 2007, Microsoft has a global annual revenue of US$51.12 billion and nearly 79,000 employees in 102 countries. It develops, manufactures, licenses, and supports a wide range of software products for computing devices.
