History of Microsoft and Its Major Milestones

Inspired by an article in an electronics magazine, Microsoft would grow exponentially to dominate the tech market today.

Microsoft is one of the most successful tech companies in history, with a market capitalization of just over $1 trillion. Its products are used by hundreds of millions of people every day, and its logo is one of the most recognized around the world

Here, we explore Microsoft's earliest days and answer some of the most commonly asked questions about the company. This article is, however, intended primarily as an overview of the company and not as a comprehensive history.

When and where did Microsoft start?

The company that would eventually become Microsoft was first founded by Bill Gates and Paul Allen in Albuquerque, New Mexico, in 1975.

The pair were avid programming enthusiasts from a young age. Building on their existing skills, they were inspired to produce their own programming language, Microsoft BASIC, based on the existing language BASIC.

Taking around eight weeks to compile, the pair of plucky entrepreneurs demonstrated BASIC for Micro Instrumentation and Telemetry Systems (MITS),  the company that built the Altair 8800 microcomputer.

MITS liked what they saw and agreed to distribute and market the product under the name of Altair BASIC. This deal inspired Gates and Allen to found their own software company, and in April of 1975, Microsoft was born. 

"When we signed that first contract with MITS, we referred to ourselves as 'Paul Allen and Bill Gates doing business as Micro-Soft.' I don't remember why we spelled it with a hyphen and a capital 'S.' We put a credit line in the source code of our first product that said, 'Micro-Soft BASIC: Bill Gates wrote a lot of stuff; Paul Allen wrote some other stuff.'" - Bill Gates.

From that moment on, Microsoft would continue to grow until it eventually became the tech giant we all know (or love and hate in equal measures) today.

How did Bill Gates come up with Microsoft?

In short, he didn't — at least not on his own. The basic (pun intended) idea was mainly Paul Allen's. 

In what is now something of a legend, the idea for Microsoft came in a moment of inspiration for Paul Allen. Back in 1975, at the time, Gates was an undergraduate at Harvard University, and Allen worked for Honeywell Inc. as a computer programmer. 

Allen, at the time 22-years old, purchased a copy of the January edition of Popular Electronics. On the front cover was an image of the World’s First Minicomputer Kit — the Altair 8800 microcomputer.

Allen read the related article and struck on an idea. With his copy of Popular Electronics in hand, he decided to pay his school-friend Bill Gates a visit. 

The two had been friends since their early days at Lakeside School (a private preparatory school in Seattle) and shared a passion for computers and programming. In fact, they had both become accomplished programmers and had been hired in 1971 to write a payroll program for Information Sciences, Inc. on behalf of COBOL. 

Allen made his pitch to Gates. His idea was to adapt the Beginner’s All-purpose Symbolic Instruction Code (BASIC) for the Altair 8800.

Gates was impressed and liked the idea. He was also persuaded by Allen to leave Harvard to pursue their business idea. 

At that time, microcomputers like the Altair 8800 executed source code provided by the machine's compiler, but lacked an interpreter. Paul Allen proposed using BASIC to develop such an interpreter. 

If successful, this BASIC-based interpreter would make machines like the 8800 very appealing to hobbyists and professional programmers around the world. Allen believed it would also enable the cost of microcomputers to fall dramatically, making software development a viable business on a larger scale.

With their pitch and interpreter prototype completed, the pair approached MITS to give an in-person demonstration. Ed Roberts, the founder of MITS, agreed to the meeting, loved what he saw, and agreed to distribute a new machine which included their software - Altair BASIC.

In February of 1975, Allen and Gates sold their code to MITS for $3,000 (around $14,000 today), plus a percentage of royalty payments (worth around $840,000 today).

The same year "Micro-Soft" was officially registered as a company. The rest, as they say, is history. 

Where did the Name Microsoft come from?

Back in 1975, Gates and Allen had mused over a few possible names for their new venture. 

"We had talked about a lot of different names back in Boston, and at some point, I said, 'Well, the totally obvious name would be [Micro-Soft].'" - Paul Allen.

But there were other options on the table. 

"We also had mentioned names like Outcorporated Inc. and Unlimited Ltd., but we were, you know, joking around. We talked a lot about whether we should call it Allen & Gates, but decided that was not a good idea." - Bill Gates.

But the name "Micro-Soft" stuck. It was created by Allen as a portmanteau of "microcomputer" and "software."

After officially forming a company, the pair would later open their first international office in Japan, called ASCII Microsoft, in 1977.

Two years later, in 1979, the company relocated to Bellevue, Washington, and eventually incorporated as Microsoft Inc. in 1981.

Bill Gates would take on the role of President of the company and Chairman of the Board, and Paul Allen became the company's Executive Vice President.

So, there we go. 

Today, Microsoft has grown to be a world leader in the tech industry. From humble beginnings in the 1970s, hard work and attention to detail would create one of the most successful companies of all time.
