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 Windowsoperating system and the Microsoft Office suite of productivity software.
In 1980, Microsoft formed a partnership with IBM that allowed them to bundle Microsoft’s operating system with IBM computers, paying Microsoft a royalty for every sale. In 1985, IBM requested that Microsoft write a new operating system for their computers called OS/2; Microsoft wrote the operating system, but also continued to sell their own alternative, which proved to be in direct competition with OS/2. Microsoft Windows eventually overshadowed 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 2013, Microsoft has a global annual revenue of US$ 77.85 billion and nearly 110,000 employees in 105 countries. It develops, manufactures, licenses, and supports a wide range of software products for computing devices.
