Microsoft Corp

Headquartered in Redmond, Washington, Microsoft Corporation operates as an American multinational technology conglomerate. Founded in 1975, the firm gained prominence in the personal computer revolution through software like Windows and has since expanded into internet services, cloud computing, video gaming, and other domains. Recognized as the world’s largest software provider, one of the most valuable U.S. public enterprises, and a globally iconic brand, Microsoft shapes the tech landscape.

Co-founded by Bill Gates and Paul Allen to develop and market BASIC interpreters for the Altair 8800, Microsoft emerged as a dominant force in PC operating systems with MS-DOS in the mid-1980s, succeeded by Windows. Between 1980 and 2021, the company released nine MS-DOS versions (median interval: 2 years) and thirteen Windows versions (median interval: 3 years). Its 1986 IPO and subsequent stock growth created three billionaires and approximately 12,000 millionaires among employees. Since the 1990s, it has diversified beyond operating systems. Steve Ballmer succeeded Gates as CEO in 2000, overseeing the 2011 acquisition of Skype Technologies (then Microsoft’s largest deal), a hardware push leading to the 2012 debut of its in-house Surface PCs, and the formation of Microsoft Mobile through Nokia.

Under Satya Nadella’s leadership (since 2014), Microsoft shifted focus to cloud computing, highlighted by the $26.2 billion 2016 acquisition of LinkedIn. Nadella also expanded gaming, establishing the Microsoft Gaming division in 2022 and acquiring Activision Blizzard for $68.7 billion in 2023, reinforcing Xbox’s global presence.

Since the 1990s, Microsoft has dominated IBM PC-compatible OS and office software markets. Notable products include Windows OS, Microsoft Office/Microsoft 365 (featuring Word, Excel, PowerPoint), Surface PCs, Xbox consoles/network, and services like Bing, MSN, Outlook.com, and Microsoft Store. In enterprise/development, it offers Azure cloud, SQL Server, and Visual Studio.

Counted among the Big Five U.S. tech giants (with Alphabet, Amazon, Apple, Meta), Microsoft hit a $1 trillion market cap in April 2019, the third U.S. firm to achieve this milestone. While criticized for monopolistic practices and software usability/security issues, its innovations continue to define industry standards.
