William Henry Gates III cofounded the Microsoft Corporation in 1975, built his software company into the one of the most successful businesses in the world, and established himself in the process as the world's richest man. Although Bill Gates started Microsoft as a small business based on a single innovative software program that he had helped to develop, his real genius was his business acumen. As the long-time CEO of Microsoft, Gates was able to borrow and integrate other computer programmers' innovations and sell them to a new and rapidly expanding home computer market. In 1985, 10 years after Microsoft was founded, it had $140 million in revenue, which grew to $28 billion by 2002. One of the pioneers of home computing, Gates proved himself to be a technological visionary and software applications guru. According to industry analysts, he also demonstrated that he was a shrewd marketing strategist as well as an aggressive corporate leader.
