Company History
Founded 1975 in Redmond, Washington, United States
Microsoft was founded in 1975 by Bill Gates and Paul Allen and evolved from PC software into a global platform spanning cloud, productivity, operating systems, gaming, developer tools, security, and AI.
Microsoft possesses arguably the most iconic, foundational founding story of the entire personal computing revolution, rooted in the intense, brilliant partnership of two teenage computer prodigies who recognized the software potential of the microcomputer before anyone else. The company was founded in 1975 in Albuquerque, New Mexico, by Bill Gates and Paul Allen. The two brilliant, obsessed childhood friends from Seattle had famously spent their teenage years hacking into corporate mainframe computers simply to score free expensive computing time. Their world-changing 'eureka' moment occurred in January 1975 when Paul Allen saw an obscure magazine cover (Popular Electronics) featuring the Altair 8800 (the world's very first commercially viable microcomputer). Allen excitedly showed it to Gates. They immediately realized a fundamental truth: this tiny, primitive computer was useless because it lacked a functional programming language. In a legendary feat of engineering brilliance, Gates and Allen wrote a version of the BASIC programming language for the Altair in just a few weeks, without ever physically touching the actual machine (using a complex emulator). They founded 'Micro-Soft' to sell the software. However, their masterstroke occurred in 1980. When IBM desperately needed an operating system for its secretive new Personal Computer, Gates bought a rudimentary operating system (QDOS) for $50,000, slightly modified it into MS-DOS, and licensed it to IBM. By retaining the right to license MS-DOS to *other* computer manufacturers, Bill Gates established the foundational architecture of the immensely powerful software monopoly that dominated the 20th century.
Paul Allen co-founded Microsoft and was crucial to its earliest technical and strategic decisions. He helped develop Altair BASIC, gave the company its original name, and participated in the operating-system opportunity that led to MS-DOS. Allen left active management in the early 1980s after being diagnosed with Hodgkin lymphoma, though he remained a major shareholder for many years. After Microsoft, he became an investor, philanthropist, sports-team owner, and backer of science, space, music, artificial intelligence, and cultural institutions through Vulcan Inc. His lasting influence on Microsoft is easy to understate because he exited daily operations early, but the company might not have existed without his ability to see the Altair as a commercial signal rather than a hobbyist curiosity. Allen represented the imaginative technical side of Microsoft's founding: the belief that small computers would become general-purpose tools if software could make them useful.
Microsoft acquired LinkedIn to integrate professional networking data into its enterprise ecosystem. The goal was to enhance customer relationship management, recruitment tools, professional advertising, and sales intelligence. It also gave Microsoft a major professional identity graph outside Windows and Office.
Microsoft acquired GitHub to rebuild trust with developers, strengthen its open-source posture, and place itself closer to the software development workflow. The acquisition also created a natural bridge between code repositories, developer tools, GitHub Enterprise, GitHub Actions, Copilot, and Azure.
Microsoft acquired Nuance to deepen its position in healthcare AI, speech recognition, clinical documentation, and conversational intelligence. The deal gave Microsoft specialized industry software that could run on Azure and support healthcare workflows.
Microsoft acquired ZeniMax Media, parent of Bethesda Softworks, to expand its first-party gaming portfolio. The deal added franchises such as The Elder Scrolls, Fallout, Doom, and other content that could strengthen Xbox and Game Pass.
Microsoft acquired Activision Blizzard to gain major gaming franchises, mobile exposure through King, and a larger content base for Xbox, PC, Game Pass, and cloud gaming. The strategic logic was to reduce dependence on console cycles and strengthen Microsoft's position in interactive entertainment.
Since its establishment in 1975, Microsoft Corporation expanded from an early-stage venture into a recognized leader in Software, Cloud Computing, Artificial Intelligence, Gaming, and Enterprise Technology, overcoming key market challenges.
Over its history, Microsoft Corporation executed decisive strategic pivots toward scalable monetization and digital distribution, securing its current market leadership.
By continually modernizing operations and embracing workflow automation, Microsoft Corporation maintains resilience through changing technological and economic cycles.
