Microsoft — How Two Friends Turned a Magazine Cover Into the World's Software Empire
From a two-person startup in Albuquerque to a multi-trillion-dollar cloud and AI powerhouse, this is the story of the company that taught the world to compute.
In January 1975, a college dropout and his childhood friend saw a photo of a tiny computer on a magazine cover and made a bet on the future. That bet became Microsoft — the company whose software would run the majority of the world's personal computers, reshape how people work, and eventually become one of the most valuable companies on Earth. This is the complete, verified timeline of Microsoft, told the way history deserves to be told.

Few companies have shaped modern life as deeply as Microsoft. When Bill Gates and Paul Allen founded it in 1975, personal computers barely existed. Within two decades, Microsoft's Windows operating system and Office productivity suite had become the invisible infrastructure of offices, schools, and homes across the planet.
The company's journey is not a straight line of triumph. It is a story of a fierce, competitive startup that outmaneuvered giants like IBM, dominated the PC era so completely that governments accused it of monopoly, stumbled badly in the age of mobile and the internet, and then — under a new kind of leader — reinvented itself around cloud computing and artificial intelligence.
This timeline traces Microsoft from a handwritten BASIC interpreter for the Altair 8800 to Windows 95 launch-night mania, from antitrust courtrooms to the $3 trillion club. Every date, name, and figure below has been cross-checked against authoritative sources, including Microsoft's own corporate records, Britannica, and major financial reporting.
- January 1975The Altair 8800 Sparks an Idea
A magazine cover changes two young lives.
The January 1975 issue of Popular Electronics featured the Altair 8800, an early personal computer. Bill Gates and Paul Allen saw it as a machine that desperately needed software. They contacted MITS, the Altair's maker in Albuquerque, offering a BASIC programming language interpreter.
This moment set in motion the founding of Microsoft and, arguably, the mass-market software industry.
Gates and Allen developed and demonstrated their BASIC before they had a company to sell it through.
- 1975Microsoft Is Founded
"Micro-Soft" is born in Albuquerque.
Gates and Allen formed their partnership in 1975 to market their BASIC interpreter. Allen coined the name "Micro-Soft," a blend of "microcomputer" and "software." Their first employee was high-school friend Ric Weiland.
The founding date the company itself recognizes as its birth.
In a July 29, 1975 letter, Gates used the name "Micro-Soft" — the earliest known written reference. The hyphen was later dropped.
- January 1, 1979Move to the Seattle Area
Microsoft relocates to Bellevue, Washington.
The company moved from Albuquerque to Bellevue, Washington — closer to Gates's and Allen's hometown of Seattle — as it grew beyond its startup roots.
Anchored Microsoft in the Pacific Northwest, which became a global technology hub.
The Seattle region remains Microsoft's home nearly half a century later.
- 1980–1981The IBM Deal and MS-DOS
Microsoft supplies the operating system for the IBM PC.
IBM approached Microsoft for an operating system for its upcoming personal computer. Microsoft provided MS-DOS (a 16-bit operating system). On August 12, 1981, IBM introduced its PC running MS-DOS 1.0. Crucially, Microsoft retained the right to license the software to other manufacturers.
This deal is widely seen as the foundation of Microsoft's dominance — licensing DOS to the entire clone market made it the industry standard.
The decision to keep licensing rights, rather than sell outright to IBM, became one of the most consequential business moves in tech history.
- June 25, 1981Microsoft Incorporates
The partnership becomes a corporation.
Microsoft formally incorporated in 1981, restructuring from a partnership into Microsoft Corporation.
A legal and organizational milestone as the company professionalized.
Incorporation came the same year the IBM PC launched with Microsoft software.
- November 1985The First Windows
Microsoft launches Windows 1.0.
Microsoft released the first version of Windows, a graphical operating environment that ran on top of MS-DOS, offering a mouse-driven interface with windows and menus.
Windows would become the world's dominant PC operating system, though early versions saw modest adoption.
It took several versions before Windows became a mainstream success.
- February–March 1986Redmond Campus and the IPO
A new home and a landmark stock debut.
On February 26, 1986, Microsoft moved to its corporate campus in Redmond, Washington. On March 13, 1986, Microsoft went public. The IPO priced shares at $21; by the end of the first trading day the stock stood around $28.
The IPO created enormous wealth — reportedly three billionaires and an estimated 12,000 millionaires among employees over time — and funded decades of growth.
The offering raised roughly $61 million and gave Microsoft a market capitalization of about $777 million.
- August 1, 1989Microsoft Office Debuts
The productivity suite that conquered offices.
Microsoft introduced its earliest version of the Office suite, bundling productivity applications such as Word and Excel.
Office became one of the most widely used software products in the world and a durable pillar of Microsoft's revenue.
Decades later, Office evolved into the subscription service Microsoft 365.
— The Bet (1975–1980)
Two friends who had bonded over computers as teenagers saw an opportunity most people missed: the personal computer would need software, and lots of it. They built a BASIC interpreter for the Altair 8800 and founded Micro-Soft to sell it. In these lean early years, Microsoft was a scrappy band of programmers writing languages for the earliest microcomputers.
— The Standard (1980–1995)
The IBM deal transformed everything. By supplying MS-DOS and keeping the right to license it widely, Microsoft became the default operating system for the exploding PC industry. Windows layered a graphical face on top, and with Windows 3.0 and then the phenomenon of Windows 95, Microsoft became the software heartbeat of the world's computers. Office locked in its grip on the workplace.
— The Giant Under Fire (1995–2014)
Dominance brought scrutiny. Antitrust regulators challenged Microsoft's power. The company launched Xbox and Windows XP, thrived in enterprise software, but was caught flat-footed by the rise of the internet, search, smartphones, and mobile operating systems, where rivals surged ahead.
— The Reinvention (2014–Present)
Satya Nadella refocused Microsoft on the cloud with Azure, embraced subscriptions with Microsoft 365, acquired LinkedIn and later Activision Blizzard, and made a defining bet on artificial intelligence through OpenAI. The result was one of the great corporate comebacks — culminating in a market value above $3 trillion.

Microsoft has faced significant controversy, most notably a major U.S. antitrust case around the late 1990s concerning its market dominance and the bundling of Internet Explorer. It also encountered antitrust scrutiny in the European Union in the 2000s. The company has periodically drawn criticism over competition practices and the pace of some product transitions. These disputes are presented here as documented business and legal history.
Microsoft and its leaders have received extensive recognition in business and technology. The company is consistently ranked among the world's most valuable and influential corporations. Its 1986 IPO was widely praised at the time. Its leaders, including Bill Gates and Satya Nadella, have been repeatedly recognized among the most influential figures in technology and business. (Specific individual awards are summarized generally where exact details could not be independently verified.)
Microsoft is one of the most recognized brands in the world. Windows and Office are used by vast numbers of people daily; Xbox has a large global gaming community; and Azure serves businesses worldwide. The company's brand is synonymous with personal and enterprise computing.
As of 2026, Microsoft sits at the center of the two defining technology trends of the era: cloud computing and artificial intelligence. Its Azure platform powers a huge share of global digital infrastructure, its productivity tools remain essential to work and education, and its AI investments shape how businesses and individuals use intelligent software. Understanding Microsoft's history helps explain how the modern digital world was built — and where it may be heading.

SHORT SUMMARY: Microsoft, founded in 1975 by Bill Gates and Paul Allen, became the dominant force in personal-computer software through MS-DOS, Windows, and Office, and later reinvented itself as a cloud and AI leader worth over $3 trillion.
MEDIUM SUMMARY: Starting with a BASIC interpreter for the Altair 8800, Microsoft rose to power by supplying MS-DOS for the IBM PC and licensing it widely. Windows and Office made it ubiquitous. After a 1986 IPO and years of dominance — and a landmark antitrust battle — the company navigated leadership changes from Gates to Ballmer to Nadella. Under Nadella, Microsoft pivoted to cloud computing with Azure, acquired LinkedIn, invested heavily in OpenAI, and reached a market value above $3 trillion.
LONG SUMMARY: Microsoft's story spans the entire personal-computer era. Founded in 1975 in Albuquerque by childhood friends Bill Gates and Paul Allen, it began by writing programming languages for early microcomputers. The pivotal 1980–1981 deal to supply MS-DOS for the IBM PC — while retaining licensing rights — made Microsoft's software the industry standard. Windows, launched in 1985 and popularized by Windows 3.0 and the blockbuster Windows 95, defined desktop computing, while Office conquered the workplace. The 1986 IPO created immense wealth. At its peak, Microsoft's dominance triggered a major antitrust case. Leadership passed to Steve Ballmer in 2000, who expanded into gaming with Xbox and hardware with Surface but saw Microsoft trail in search and mobile. In 2014, Satya Nadella became CEO and led a historic turnaround centered on cloud computing (Azure), subscriptions (Microsoft 365), major acquisitions (LinkedIn, and later Activision Blizzard), and a defining bet on artificial intelligence via OpenAI. By January 2024, Microsoft surpassed a $3 trillion market capitalization, cementing its place among the most valuable and influential companies in history.
