Entrepreneur Profile: Bill Gates
What was the replacement operating system for MS-DOS?
Hi! This is Meghan Lynn Allen for About.com, and today we'll talk about entrepreneur Bill Gates.Bill Gates, the son of an attorney, started rudimentary programming at just 13 years old. His first program was a very basic version of tic-tac-toe. He sold his first application to a school for $4,000, and he began a business with his friend Paul Allen in 1976 and called it Microsoft. Bill Gates became a Harvard dropout to focus on his own software business. By 1980, Bill and Paul became major players in the industry.They convinced IBM to let them write the operating system for their brand new PC. They called it MS-DOS, and importantly, they were able to license it for non-IBM computers. Easy and broad network compatibility was a big factor in operating system growth. Bill used the success of MS-DOS to usher in Windows 1.0 in 1985.Later versions of Windows gained increasing market share versus Apple's Macintosh products. Bill, who early on was more of a software programmer, transitioned into more of an executive role. In 1986, Microsoft appeared on the New York Stock Exchange.The replacement for MS-DOS, Windows, became more sophisticated, more ubiquitous, and on more than 90 percent of PCs in the 90s and 2000s. Even as the industry sees phenomenal growth in the area of smartphones and tablets, Windows is still by far the dominant PC operating system. Office programs such as Word and Excel are the default business standard.Bill Gates steered Microsoft through a massive antitrust lawsuit for bundling Internet Explorer with Windows, ultimately blocking competitors. In the end, the lawsuit was settled with minor concessions to third parties. Bill Gates stepped down as CEO in the year 2000, and his last official day of work was in 2008.Post-2008, Bill devotes most of his time to the Bill and Melinda Gates Foundation, which deals with global poverty and health problems - prominently, malaria. The charity is worth over 30 billion, one of the most highly valued charities in the world.Thanks for watching. To learn more, visit us on the web at About.com.
