Bill Gates is the co-founder of the software company Microsoft and is one of the world's wealthiest men. Gates and Paul Allen founded Microsoft in the 1970s, though Allen left the company in 1983. Bill Gates oversaw the invention and marketing of the MS-DOS operating system, the Windows operating interface, the Internet Explorer browser, and a multitude of other popular computer products. Along the way he gained a reputation for fierce competitiveness and aggressive business savvy. During the 1990s rising Microsoft stock prices made Gates the world's wealthiest man; his wealth has at times exceeded $75 billion, making Gates a popular symbol of the ascendant computer geek of the late 20th century. In June of 2006, Gates announced that he would step down from day-to-day involvement in Microsoft by July of 2008. He did so and was succeeded as CEO by Steve Ballmer.
