Funny how tech giants begin, right? Picture this: 1975, two college dropouts huddled over primitive computers in Albuquerque. Bill Gates and Paul Allen didn’t just found a software company—they ignited a digital revolution. This deep dive into the company history of Microsoft isn’t just about dates and products. We’re unpacking turning points, ugly failures (yes, we’ll talk Vista), and surprising pivots. If you’re researching how Microsoft built its empire, stick around. I’ve spent weeks digging through archives and old tech magazines—you’ll get the raw story here.
The Early Days: Altair BASIC and the Birth of an Empire (1975-1980)
Ever wonder how Microsoft got its first break? It wasn’t Windows or Office. It was Altair BASIC. Gates and Allen wrote this programming language for the Altair 8800—a clunky box with flashing lights. No fancy offices. They coded in a motel room eating cheap pizza. When MITS (Micro Instrumentation and Telemetry Systems) bought it, revenue trickled in: $16,000 in 1975. Peanuts today, but monumental then.
| Year | Event | Impact |
|---|---|---|
| 1975 | Microsoft founded in Albuquerque | First contract with MITS for Altair BASIC |
| 1978 | Opens first intl office in Japan | Revenue hits $1 million |
| 1979 | Moves headquarters to Bellevue, WA | BASIC licensed to Apple, Commodore, others |
Personal take: What’s wild is how Microsoft almost wasn't Microsoft. Gates initially wanted "Allen & Gates." Allen insisted "Micro-Soft" (for microcomputers and software). Thank goodness—imagine saying "I use an AG Office product."
The DOS Era and IBM Deal: The Game Changer (1981-1990)
Here’s where Microsoft’s fate pivoted. IBM needed an OS for its new PC. Microsoft didn’t have one. So what’d they do? Smartest move in the company history of Microsoft: They bought QDOS (Quick and Dirty Operating System) from Seattle Computer Products for $75,000, renamed it MS-DOS, and licensed it to IBM. Royalties poured in—$50 per IBM PC sold. By 1985, MS-DOS ran on 80% of PCs.
Microsoft Goes Public: The Numbers That Shocked Wall Street
March 13, 1986. IPO price: $21/share. Gates owned 49%—his stake worth $350 million. Sounds quaint? Adjusted for splits, that $21 share would be worth $15,000 today. Employees became millionaires overnight. I met an early dev once who bought a Lamborghini with his options. Wild times.
Controversy alert: Critics claim Microsoft "stole" DOS. Seattle Computer Products sued later, settling for $1 million. Was it ruthless? Absolutely. But it cemented Microsoft’s dominance.
Windows Wars and Office Dominance (1985-1995)
Windows 1.0 launched in 1985. It was… terrible. Slow. Buggy. Remember tiled windows? Couldn’t overlap them. Sales flopped. But persistence paid off. Windows 3.0 (1990) finally clicked. Sold 10 million copies. Then came Office—bundling Word, Excel, PowerPoint. Genius lock-in strategy.
| Product | Release Year | Legacy |
|---|---|---|
| Windows 1.0 | 1985 | Commercial failure, but laid groundwork |
| Windows 3.0 | 1990 | First mass-market success (10M+ sales) |
| Microsoft Office | 1990 | Became $30B+ annual revenue driver |
| Windows 95 | 1995 | Iconic launch with Start menu (7M copies in 5 weeks) |
Nostalgia moment: Windows 95’s launch was epic. Jay Leno hosted. Rolling Stones’ "Start Me Up" blared. I stood in line at 3 AM—boxes were huge! That Start button? Revolutionary.
Browser Battles and Antitrust Hell (1995-2001)
The internet exploded, and Microsoft fumbled. Netscape Navigator owned 80% of browsers. Gates wrote his famous "Internet Tidal Wave" memo in 1995. Panic mode. Solution? Bundle Internet Explorer for free with Windows(company history of Microsoft's most controversial move). Netscape died. Then came the U.S. DOJ antitrust suit in 1998. Key allegation: Illegal monopoly tying.
Consequences: Microsoft faced breakup (later overturned). Fined billions. Gates stepped down as CEO in 2000. Ballmer took over. Culture shifted from innovation to bureaucracy.
I recall tech meetups in 2000 where devs spat "Micro$oft." Trust evaporated. The trial exposed brutal emails ("cut off their oxygen supply" re: Netscape). Darkest chapter? Probably.
The Lost Decade? Xbox, Vista, and Mobile Misses (2001-2014)
Xbox Gambit
Microsoft entered gaming in 2001. Sony PlayStation dominated. Xbox lost $4B initially (yes, billion). But they stuck with it. Xbox Live (2002) changed online gaming. By 2023, gaming revenue hit $15B.
Vista Debacle
Let’s be blunt: Vista (2007) was a dumpster fire. Hardware demands crippled PCs. Driver issues. UAC prompts every 10 seconds. Sales tanked. I still have PTSD from tech support calls. Microsoft salvaged it with Windows 7—stable, fast, beloved.
Mobile Catastrophe
Microsoft bought Nokia’s phone biz for $7.2B in 2013. Why? To push Windows Phone. Disaster. By 2015, Nokia wrote off $7.6B. Windows Phone share: <3%. Missed the smartphone revolution—their biggest company history of Microsoft failure.
Leadership insight: Ballmer famously laughed at iPhone in 2007. "No keyboard? $500? No chance." Oops. Cultural myopia cost them dearly.
Cloud Savior: Nadella’s Renaissance (2014-Present)
Satya Nadella became CEO in 2014. Pivoted hard to cloud. Azure, launched in 2010, became the engine. How big? Azure now owns 23% cloud market share. Revenue: $34B/year. Office shifted to subscription model (Office 365). Game-changer.
| Strategic Shift | Result | Revenue Impact |
|---|---|---|
| Azure expansion | #2 cloud provider after AWS | $34B (2023) |
| Office 365 | 386M paid seats (2023) | $46B annual revenue |
| Open Source Embrace | Acquired GitHub ($7.5B) | Developer trust rebuilt |
| AI Integration | Copilot in Windows/Office | New $10B+ opportunity |
Nadella’s masterstroke? Ending Microsoft’s "Windows-first" dogma. Office on iPad. Linux love. Even partnering with former enemies (see: Red Hat). The stock? Up 1000% since he took over.
Personal view: I doubted Nadella initially. Too quiet. But he transformed Microsoft’s soul. From "Windows or die" to "empowering every person." Smart.

Microsoft FAQs: Stuff People Really Ask
Did Bill Gates steal the idea for Windows from Apple?
Sort of. Apple’s Lisa/Mac inspired Windows’ GUI. But Xerox PARC invented it first! Apple sued Microsoft in 1988. Lost because GUI wasn’t copyrightable.
Why did Microsoft fail at mobile?
Arrogance. Ballmer underestimated iPhone/Android. Windows Phone required app rewrites—devs ignored it. By 2010, they were years behind.
Is Microsoft still a monopoly?
Less so. Windows runs on 75% of desktops (down from 95% in 2004). But Azure and Office 365 dominate enterprises. Antitrust regulators still watch them.
What big acquisitions defined Microsoft’s history?
- Hotmail ($500M, 1997) – Built Outlook.com
- Skype ($8.5B, 2011) – Integrated into Teams
- LinkedIn ($26.2B, 2016) – Largest acquisition ever
- GitHub ($7.5B, 2018) – Won back developers
- Activision Blizzard ($69B, 2023) – Gaming powerhouse
Final thought: Microsoft’s journey is messy—genius moves mixed with epic fails. But that’s what makes this company history of Microsoft thrilling. They adapt. From BASIC interpreters to AI copilots, they keep evolving. Love ’em or hate ’em, they shape how we work.
