Who Founded Microsoft and When
Bill Gates co-founded Microsoft in 1975 with Paul Allen, establishing the company to develop software for personal computers. The pair started writing interpreters for the Altair 8800, one of the earliest microcomputers, which marked the true beginning of Microsoft's history. Gates served as chairman, CEO, and later chief software architect, shaping the company's strategy for decades. This founding story is widely documented by major business sources such as Forbes.
Before Microsoft, Gates was a student at Harvard University and had already worked on programming projects with Allen. Their partnership was rooted in a shared vision that software would become the core of computing. The company's first office was in Albuquerque, New Mexico, where they focused on adapting BASIC for different hardware platforms. By the late 1970s, Microsoft had begun to position itself as a leading independent software developer.
What Was Microsoft's First Product
Microsoft's first product was a version of the BASIC programming language for the Altair 8800, which the company licensed to MITS in 1975. This interpreter allowed hobbyists and early computer users to write and run programs, giving Microsoft its first commercial revenue and customer base. The deal with MITS is considered the official start of Microsoft's product business.
After the Altair BASIC success, Microsoft expanded into other languages and operating systems. The company later developed MS-DOS, which became the standard operating system for IBM-compatible PCs and drove massive growth in the 1980s. Gates and Allen's early focus on programming languages and system software laid the foundation for Microsoft's dominance in the PC era.
How Microsoft Grew From Its First Product
From Altair BASIC to Global Software Leader
Microsoft's transition from a small language developer to a global software leader began with the IBM PC deal in 1980. The company provided the operating system that became MS-DOS, which was bundled with millions of IBM computers. This partnership gave Microsoft a dominant position in the PC operating system market and set the stage for future products like Windows.
Windows and the Modern Era
The release of Windows in 1985 introduced a graphical user interface to IBM PC users and gradually replaced MS-DOS as the primary platform. Over the following decades, Microsoft expanded into productivity software, cloud computing, gaming, and enterprise services. Today, Microsoft is one of the most valuable companies in the world, with products such as Azure, Office 365, and Xbox shaping multiple industries.
Key Milestones and Current Position
Microsoft's market capitalization has consistently ranked among the highest globally, reflecting its leadership in cloud services and enterprise software. The company continues to invest in artificial intelligence, cybersecurity, and productivity tools, building on the legacy of its first product. This evolution from a single BASIC interpreter to a diversified technology giant is a central case study in modern business history.
