An Idea Before Its Time
In the early 1970s, computers were colossal machines owned by corporations, universities, and governments. They were the exclusive domain of engineers and academics. The notion of a 'personal computer' was a niche fantasy for electronics hobbyists. In this
world, hardware was king. The value was in the physical machine, the circuits and steel. Software was often an afterthought, a set of instructions written for one specific machine and typically shared freely among enthusiasts. The idea that software could be a standalone product—something you could package and sell—was not just unpopular; it was almost unthinkable. This was the environment where two young programmers from Seattle, Bill Gates and Paul Allen, began to form a truly radical business concept.
A Failed Venture and a Fateful Magazine
Before Microsoft, there was Traf-O-Data. It was a small company Gates and Allen started to process traffic data from roadside counters for local governments. The venture was a commercial failure, but it gave them crucial experience, particularly in writing software for a microprocessor they didn't physically possess. This skill would soon become invaluable. The real spark came in January 1975, when Allen spotted the cover of 'Popular Electronics' magazine. It featured the Altair 8800, a build-it-yourself computer kit for hobbyists. To Gates and Allen, it wasn't just a machine; it was a signal that the era of the personal computer was beginning, and every one of those machines would need software.
The Ultimate Bluff
Seizing the moment, Gates and Allen called MITS, the company behind the Altair, and made a bold claim: they had a version of the popular programming language BASIC that could run on the new computer. This was a complete bluff. They had not written a single line of code and didn't even own an Altair. MITS's founder, Ed Roberts, agreed to a demonstration in just a few weeks. A frantic period of work followed. Allen adapted their old Traf-O-Data emulator to simulate the Altair on a university mainframe computer, while Gates, joined by fellow student Monte Davidoff, wrote the core of the BASIC interpreter. Allen flew to Albuquerque for the demo, testing the code on a real Altair for the first time just moments before the meeting. It worked flawlessly.
Software as a Standalone Product
The deal they struck with MITS was the true genius of their plan. MITS got the rights to bundle Altair BASIC with its computers, but Gates and Allen retained ownership of the software itself. This meant they could license the same BASIC interpreter to other companies that would inevitably start building their own computers. This was the revolutionary idea: software wasn't just a feature of one machine; it was a universal, licensable product. They formed 'Micro-Soft'—a name Allen suggested, for microcomputer software—on this principle. The initial money wasn't from venture capitalists, who would have likely balked at the idea, but from the licensing deal itself, which paid royalties on every copy sold.
Fighting for the Concept
The initial resistance wasn't just from a skeptical business world, but from the very users they were trying to serve. Early computer hobbyists were accustomed to sharing software for free. Piracy of Altair BASIC was rampant, with copies of the program's paper tape passed around at club meetings. In response, a frustrated 20-year-old Gates wrote his famous 'Open Letter to Hobbyists' in 1976. He argued that paying for software was essential to fund its creation and improvement, asking, "Who can afford to do professional work for nothing?" The letter was controversial and received a largely negative response, but it was a defining moment. It was a declaration that software had commercial value, establishing the fundamental business model that would fuel the entire personal computer revolution and build an empire.
