The Story of Microsoft

On April 4, 1975, Bill Gates and Paul Allen founded Microsoft with a shared vision of creating software for the emerging world of personal computers. Inspired by the release of the Altair 8800, one of the first microcomputers available to the public, the two saw an opportunity to make computers more useful through software.

At the time, Gates was a student at Harvard University, while Allen was working as a programmer. After seeing the Altair featured in a magazine, they contacted its manufacturer and offered to develop a programming language for it—even before they had fully created the software. This bold move led them to develop Altair BASIC, which became Microsoft’s first product.

In its earliest days, Microsoft was a very small operation, with Gates and Allen handling most of the work themselves, from coding to business negotiations. The company was originally called “Micro-Soft,” combining “microcomputer” and “software,” reflecting its focus on providing software for small, personal computers. This founding marked the beginning of a company that would go on to shape the future of computing worldwide.

On July 1, 1975, a small but groundbreaking piece of software called Altair BASIC was introduced, marking both the first product and the beginning of Microsoft. Earlier that year, Bill Gates and Paul Allen founded the company with a vision of creating software for the emerging world of personal computers.

Altair BASIC was developed for the Altair 8800, one of the first commercially available microcomputers. At the time, computers were extremely difficult to use, often requiring manual input through switches and hardware controls. With Altair BASIC, users could instead type simple commands using the BASIC programming language, making computers much more accessible to hobbyists and early programmers.

This innovation transformed the Altair 8800 from a complex machine into something people could actually interact with and program. More importantly, it demonstrated the value of software as a product, helping establish Microsoft’s business model and setting the stage for the future of personal computing.

In February 1976, Bill Gates published what became known as the “Open Letter to Hobbyists,” a public message addressed to early computer enthusiasts. At the time, many hobbyists were freely copying and sharing software without paying for it, including Microsoft’s Altair BASIC.

In the letter, Gates argued that software required significant time, effort, and expertise to create, and that developers deserved to be paid for their work. He criticized the widespread practice of software piracy and warned that if programmers were not compensated, it would discourage the development of high-quality software.

This letter was controversial among hobbyists, but it marked a turning point in how software was viewed. It helped introduce the idea that software was valuable intellectual property, laying the foundation for Microsoft’s business model and influencing the future of the software industry.

In November 1976, Microsoft was officially registered as a company by Bill Gates and Paul Allen under the name “Micro-Soft.” The registration took place in the state of New Mexico, where the company was then based in Albuquerque. This location was chosen because their first major client, MITS (the maker of the Altair 8800), was also located there.

At the time, Microsoft was still a very small operation with only a handful of employees—fewer than a dozen people—including the founders and a few early programmers. Despite its size, the company was already focused on developing and licensing software, particularly versions of the BASIC programming language for different computer systems.

Formalizing the business allowed Microsoft to move beyond an informal partnership and operate as a legitimate company. It enabled them to sign contracts, protect their software, and expand their work with other hardware manufacturers. This step also reflected a growing belief—strongly advocated by Gates—that software should be treated as valuable intellectual property, not freely shared. This idea would later become a cornerstone of the modern software industry.

During the late 1970s, Microsoft expanded its reach by adapting its BASIC programming language to run on multiple early personal computers, including the Apple II, Commodore PET, and TRS-80. Because each machine had different hardware, Microsoft had to modify its software for each system. This strategy allowed the company to support a wide range of computers and helped establish Microsoft as a leading provider of software across the growing personal computer market.

In 1980, Microsoft was approached by IBM to provide an operating system for its upcoming personal computer. Although Microsoft did not yet have an operating system of its own, the company seized the opportunity and agreed to deliver one.

To fulfill the contract, Microsoft acquired an existing system called QDOS (Quick and Dirty Operating System) from a small software company. They then modified and developed it into what would become MS-DOS. Instead of selling the software outright to IBM, Microsoft negotiated a licensing deal that allowed them to retain the rights to the operating system.

This strategic decision proved crucial, as it enabled Microsoft to license MS-DOS to other computer manufacturers in the future. The agreement with IBM set the stage for Microsoft’s rise as a dominant force in the personal computer industry.
