The Founding Story
Microsoft was founded in 1975 by childhood friends Bill Gates and Paul Allen. Inspired by the Altair 8800 microcomputer featured on the cover of Popular Electronics, the pair wrote a version of the BASIC programming language for it. They named their company "Micro-Soft," a blend of "microcomputer" and "software," and set up initially in Albuquerque, New Mexico, before moving to the Seattle area.
The pivotal moment came in 1980 when IBM approached Microsoft to provide an operating system for its upcoming personal computer. Microsoft bought an existing operating system, adapted it into MS-DOS, and crucially retained the right to license it to other manufacturers. As IBM-compatible PCs flooded the market, MS-DOS became the industry standard and Microsoft collected royalties on nearly every one.
Early Growth and Pivotal Moments
The launch of Windows, a graphical interface layered on top of DOS, cemented Microsoft's dominance. Windows 3.0 in 1990 and especially Windows 95 became massive commercial successes. The Microsoft Office suite, bundling Word, Excel, and PowerPoint, dominated the productivity software market.
Microsoft went public in 1986, making Gates the world's youngest self-made billionaire a few years later. By the late 1990s it was the most valuable company in the world, though it faced a landmark antitrust lawsuit from the U.S. government over its bundling practices.
Revenue and Business Milestones
For years Microsoft's revenue rested on Windows and Office licensing. When Satya Nadella became CEO in 2014, he pivoted the company toward cloud computing and subscriptions. The Azure cloud platform grew into a fierce competitor to Amazon Web Services, and Office transitioned into the subscription-based Microsoft 365.
Revenue climbed from around $60 billion in 2008 to over $110 billion by 2018 and beyond $200 billion in the mid-2020s. Microsoft rejoined Apple in the trillion-dollar club and later surpassed $2 trillion and $3 trillion in market value.
Current Scale and Impact
Microsoft's reach spans Windows, Office, Azure, the Xbox gaming division, LinkedIn (acquired for $26 billion in 2016), and GitHub. Its massive investment in OpenAI positioned it at the forefront of the generative AI wave, embedding AI assistants across its products.
What Makes Microsoft Stand Out
Microsoft's resilience is remarkable. After being written off as a legacy giant in the mobile era, it reinvented itself around cloud and AI to become one of the most valuable companies again. Its enduring strength is the deep entrenchment of its software in enterprises worldwide, creating recurring revenue and switching costs that few competitors can match.
