Microsoft was founded by Bill Gates and Paul Allen to develop and sell BASIC interpreters for the Altair 8800. It rose to dominate the personal computer operating system market with MS-DOS in the mid-1980s, followed by Windows. During the 41 years from 1980 to 2021 Microsoft released 9 versions of MS-DOS with a median frequency of 2 years, and 13 versions of Microsoft Windows with a median frequency of 3 years. The company's 1986 initial public offering (IPO) and subsequent rise in its share price created three billionaires and an estimated 12,000 millionaires among Microsoft employees. Since the 1990s, it has increasingly diversified from the operating system market. Steve Ballmer replaced Gates as CEO in 2000 which would see the then-largest of Microsoft's corporate acquisitions in Skype Technologies in 2011, and an increased focus on hardware that led to its first in-house PC line, the Surface, in 2012, and the formation of Microsoft Mobile through Nokia. Since Satya Nadella took over as CEO in 2014, the company has changed focus towards cloud computing, as well as its large acquisition of LinkedIn for $26.2 billion in 2016. Under Nadella's direction, the company has also expanded its video gaming business to support the Xbox brand, establishing the Microsoft Gaming division in 2022, which is currently the third-largest gaming company in the world by revenue, following the 2023 acquisition of Activision Blizzard for $68.7 billion.
