Microsoft

Microsoft Corporation is a public multinational corporation headquartered in Redmond, Washington, USA that develops, manufactures, licenses, and supports a wide range of products and services predominantly related to computing through its various product divisions. Established on April 4, 1975 to develop and sell BASIC interpreters for the Altair 8800, Microsoft rose to dominate the home computer operating system (OS) market with MS-DOS in the mid-1980s, followed by the Microsoft Windows line of OSs. The ensuing rise of stock in the company's 1986 initial public offering (IPO) made an estimated four billionaires and 12,000 millionaires from Microsoft employees. Microsoft would come to dominate other markets as well, notably the office suite market with Microsoft Office. The web browser created for Windows PCs is Internet Explorer.
