# Microsoft Timeline Chronological reference for the company that defined, monopolized, and then nearly lost the personal computing era — only to reinvent itself as the infrastructure layer beneath the AI revolution. [[Microsoft]] matters to the KB not as a technology story but as a power story. The company is the original template for how tech monopolies interact with government: the 1998 [[Department of Justice]] [[Antitrust]] case came closer to breaking up a tech giant than any action before or since, and its failure — sealed when the [[George W. Bush]] administration dropped the breakup pursuit — established that tech monopolies are politically too costly to dismantle. Every subsequent case against [[Google]], [[Meta]], and [[Amazon]] operates in Microsoft's shadow. Three threads make Microsoft essential KB infrastructure: the **[[OpenAI]] kingmaker deal** (Microsoft's $13B+ investment gave it exclusive access to the most powerful AI models and the economic leverage to override [[OpenAI]]'s safety governance when the board tried to fire [[Sam Altman]]), the **government contract entanglement** (Azure Government, JEDI, JWCC — Microsoft is embedded in the defense and intelligence apparatus alongside [[Amazon]], creating structural incentives for political compliance), and the **infrastructure monopoly stack** (Windows on 1B+ devices, Office/365 in every enterprise, LinkedIn holding professional identity data on 1B+ workers, GitHub hosting most of the world's code — no company controls more of the digital workplace). Sister timelines: [[OpenAI Timeline]], [[Amazon Timeline]], [[Defense Tech Timeline]]. --- ## Era 1 — Origins (1975–1980) - **April 4, 1975** — [[Bill Gates]] and Paul Allen found Micro-Soft in Albuquerque, New Mexico. Their first product: Altair BASIC, an interpreter for the MITS Altair 8800 microcomputer. Gates and Allen had met in 1968 at Lakeside School in Seattle, where they bonded over a shared obsession with the school's teletype terminal. Gates was 19, Allen 22. - **1976** — Gates writes his famous "[[Open Letter]] to Hobbyists," arguing that software piracy (people copying Altair BASIC without paying) will kill the software industry. The letter establishes a philosophical position — that software is proprietary intellectual property, not a communal resource — that defines Microsoft's business model and its conflicts with the open-source movement for decades. - **1979** — Microsoft moves headquarters to Bellevue, Washington (later Redmond). The company has 25 employees and $2.5 million in revenue. - **November 1980** — Gates secures the deal that makes Microsoft: [[IBM]] contracts Microsoft to supply the operating system for its upcoming Personal Computer. Gates doesn't have an operating system — he licenses QDOS (Quick and Dirty Operating System) from Seattle Computer Products for $50,000, adapts it as MS-DOS, and crucially retains the right to license it to other manufacturers. This is THE defining business move of the PC era. [[IBM]] gets a commodity OS. Microsoft gets a toll booth on every PC sold by every manufacturer, forever. ## Era 2 — DOS and Windows (1981–1989) - **August 1981** — MS-DOS ships with the IBM PC. The IBM-compatible PC market explodes, and every clone runs MS-DOS — giving Microsoft a monopoly not through superior technology but through licensing structure. - **1983** — Paul Allen leaves Microsoft after a Hodgkin's lymphoma diagnosis. He later describes overhearing Gates and Steve Ballmer discussing how to dilute his equity stake while he was sick — a formative breach that permanently damaged the relationship. - **November 1985** — **Windows 1.0 launches**. A graphical shell running on top of MS-DOS, it is widely panned. But Gates correctly bets that graphical interfaces are the future (having seen the Macintosh at Apple) and commits to iterating. - **March 13, 1986** — **IPO at $21/share**, raising $61 million and valuing Microsoft at $519 million. The offering creates approximately 12,000 employee millionaires — making Microsoft the template for tech IPO wealth creation. Gates, at 31, is now worth $350 million. - **June 1987** — Windows 2.0 ships. Apple sues Microsoft for copyright infringement, alleging Windows copies the Macintosh look and feel. The case drags on until 1994; Apple loses. The ruling establishes that user interface concepts aren't copyrightable — a legal foundation for the entire software industry. - **1988** — Microsoft surpasses Lotus Development to become the world's largest PC software company by revenue. - **June 1989** — **Microsoft Office introduced** — bundling Word, Excel, and PowerPoint into a single suite. The bundle strategy undercuts competitors who sell individual applications (Lotus 1-2-3 for spreadsheets, WordPerfect for word processing) and begins the Office monopoly that persists to this day. ## Era 3 — Dominance (1990–1997) - **May 1990** — **Windows 3.0 launches** — the first mass-market success for Windows. Sells 10 million copies in two years. The graphical interface is finally good enough to replace DOS for most users. - **August 24, 1995** — **Windows 95 launch** — a cultural phenomenon. Microsoft licenses the Rolling Stones' "Start Me Up" for the launch event. 7 million copies sold in five weeks. The Start button, taskbar, and 32-bit architecture set the template for desktop computing for the next two decades. Lines around the block at midnight — for an operating system. - **August 1995** — **Internet Explorer 1.0 bundled with Windows 95** — the beginning of the browser wars. Microsoft enters the web browser market by giving IE away free with every copy of Windows, a strategy designed to destroy Netscape Navigator, which charged for its browser. The bundling decision becomes the centerpiece of the [[Antitrust]] case three years later. - **1995** — MSN (Microsoft Network) launches as an online service and internet portal. - **1996** — **MSNBC created** as a joint venture between Microsoft and NBC. Microsoft later exits the venture, but the brand persists as a cable news network. - **August 1997** — Microsoft invests **$150 million in Apple**, saving the company from near-certain bankruptcy. [[Steve Jobs]] and Bill Gates appear onstage together at Macworld. The investment preserves Apple, which later becomes the most valuable company in history. This was strategic calculation, not charity: Microsoft needed Apple to survive to counter [[Antitrust]] accusations that it was a monopoly (if Apple disappeared, the monopoly argument became airtight). Microsoft also committed to continuing Office for Mac, ensuring its productivity suite remained platform-dominant. - **By 1998** — Windows runs on 90%+ of PCs worldwide. An undeniable monopoly by any standard. ## Era 4 — The Antitrust Trial (1998–2001) The Microsoft [[Antitrust]] case is the foundational modern tech antitrust story and the last serious attempt to break up a technology company. Its outcome — and particularly the [[George W. Bush]] administration's decision to drop the breakup — established the template for tech companies being functionally too big to break up. Every subsequent case against [[Google]], [[Amazon]], and [[Meta]] has failed to get further than Microsoft did. - **May 18, 1998** — The [[Department of Justice]] and 20 state attorneys general file an [[Antitrust]] suit against [[Microsoft]], alleging illegal monopoly maintenance. The core charge: Microsoft illegally tied Internet Explorer to Windows to destroy Netscape Navigator, violating Section 2 of the [[Sherman Antitrust Act]]. - **The government's case**: Microsoft used its Windows monopoly as a weapon. By bundling IE for free with every copy of Windows, Microsoft made it economically impossible for Netscape to compete — you can't sell a browser when every computer ships with a free one. Microsoft also pressured OEM manufacturers not to install Netscape, threatened to withhold Windows licenses from companies that promoted competitors, and manipulated Java (Sun Microsystems' cross-platform language) to fragment it and preserve Windows dominance. - **November 5, 1999** — **Judge Thomas Penfield Jackson issues findings of fact**: Microsoft holds monopoly power in the market for Intel-compatible PC operating systems and used that power to harm consumers. Jackson's findings are devastating — he concludes Microsoft engaged in a pattern of anticompetitive behavior specifically designed to eliminate threats to the Windows monopoly. - **April 3, 2000** — **Jackson rules Microsoft violated the [[Sherman Antitrust Act]]** — both Section 1 (illegal tying of IE to Windows) and Section 2 (monopoly maintenance). - **June 7, 2000** — **Jackson orders Microsoft broken into two companies**: one for the operating system (Windows), one for applications (Office, IE, everything else). The structural remedy is the most aggressive antitrust action against a technology company since the AT&T breakup in 1984. - **June 28, 2001** — **The DC Circuit Court of Appeals upholds the monopoly finding but reverses the breakup order**, ruling that Jackson showed bias by making public statements about the case. The appellate court sends the remedy back for reconsideration before a different judge. - **September 2001** — The [[George W. Bush]] administration's [[Department of Justice]], under Attorney General John Ashcroft, **drops the breakup pursuit entirely**. The Bush DOJ settles for a consent decree — behavioral restrictions rather than structural separation. The consent decree requires Microsoft to share APIs with third-party companies, give OEMs more flexibility to install competing software, and submit to oversight. No breakup. No meaningful structural change. - **November 2001** — **Final consent decree approved**. Microsoft agrees to restrictions on contracting practices, disclosure of APIs, and OEM flexibility. An oversight committee monitors compliance until 2011. Microsoft's monopoly remains intact. - **The RWKB lesson**: The Microsoft [[Antitrust]] case proves the structural impossibility of breaking up a tech monopoly through the American legal and political system. The judge found a monopoly. He ordered a breakup. The appeals court agreed on the monopoly finding. And then a new administration — with different political incentives — simply dropped the remedy. The pattern repeats: the [[FTC]] under [[Lina Khan]] sues [[Amazon]] in 2023, but enforcement depends on political continuity that cannot be guaranteed across election cycles. The Microsoft case is the template for why [[Antitrust]] enforcement against tech consistently fails. ## Era 5 — Diversification and Vista (2001–2010) - **November 15, 2001** — **Xbox launches**, entering the gaming console market against Sony's PlayStation and Nintendo. Microsoft is willing to lose billions on hardware to establish a foothold in a market it considers strategically important — a classic monopoly-subsidization play, using Windows/Office profits to fund expansion into new sectors. - **2003** — Windows Server dominates enterprise computing. Microsoft's grip extends from the desktop to the data center. - **November 22, 2005** — **Xbox 360 launches**, establishing Microsoft as a serious gaming platform. The 360 generation is a commercial success and builds the Xbox Live online ecosystem. - **January 30, 2007** — **Windows Vista launches** — widely criticized for performance issues, aggressive DRM, and UAC (User Account Control) prompts that irritate users. Vista becomes shorthand for Microsoft overreach and quality decline. - **February 1, 2008** — Microsoft offers to acquire Yahoo for **$44.6 billion** — the deal would have combined Microsoft's search ambitions with Yahoo's web properties. Yahoo's board rejects the offer. In retrospect, the failed acquisition left Microsoft without a major web portal as the internet shifted from desktop software to web services. - **June 3, 2009** — **Bing search engine launches** — Microsoft's attempt to compete with [[Google]] in search. Bing never achieves significant market share (stabilizing around 3-5% globally) but becomes strategically important in 2023 when Microsoft integrates ChatGPT into it. - **July 22, 2009** — **Windows 7 launches** — restores Microsoft's reputation after Vista. Clean, fast, well-received. Windows 7 becomes the standard enterprise OS for years. - **November 4, 2010** — **Kinect for Xbox 360 launches** — a motion-sensing camera system that becomes the fastest-selling consumer electronics device in history (8 million units in 60 days). The technology is impressive; Microsoft later kills it, failing to find a sustainable business model beyond gaming. ## Era 6 — Ballmer's Last Years and the "Lost Decade" (2011–2013) Steve Ballmer's tenure as CEO (2000–2014) is retrospectively called Microsoft's "lost decade." The company missed mobile (no serious answer to iPhone/Android), missed social media (no equivalent of [[Meta]]), and was late to cloud computing. Ballmer's internal culture of "stack ranking" — forcing managers to rank employees against each other and fire the bottom tier — created a culture of internal competition that killed collaboration and innovation. Engineers spent more energy undermining colleagues than building products. - **May 10, 2011** — Acquires **Skype for $8.5 billion** — the video calling service. A premium price for a declining product that Microsoft never successfully integrated. - **June 18, 2012** — **Surface tablet launches** — Microsoft enters hardware to compete with Apple's iPad. Surface never achieves iPad-level sales but establishes Microsoft in the premium hardware market. - **June 25, 2012** — Acquires **Yammer for $1.2 billion** — an enterprise social networking service. Folded into Office 365. - **October 26, 2012** — **Windows 8 launches** — controversial tile-based interface designed for touchscreens alienates desktop users. The attempt to force a mobile paradigm onto desktop computing is rejected by users and businesses alike. - **September 3, 2013** — Acquires **Nokia's phone business for $7.2 billion** — Microsoft's attempt to compete in smartphones. The acquisition is a catastrophic failure: Microsoft writes off nearly the entire value in 2015, lays off 18,000 Nokia employees, and abandons Windows Phone. The Nokia deal is Ballmer's most expensive mistake and the clearest evidence that Microsoft's desktop monopoly could not be leveraged into mobile. ## Era 7 — The Nadella Renaissance (2014–2018) - **February 4, 2014** — **Satya Nadella becomes CEO**, replacing Ballmer. Nadella declares a "cloud-first, mobile-first" strategy — a tacit admission that Ballmer's approach failed. More importantly, Nadella transforms Microsoft's internal culture from the destructive stack-ranking competition to a "growth mindset" philosophy (borrowed from psychologist Carol Dweck). The cultural shift is as significant as the strategic one: Microsoft goes from a company where divisions sabotaged each other to one that cooperates. - **2014–2015** — **Azure cloud computing scales rapidly**. Under Nadella, Microsoft pivots hard toward cloud infrastructure, competing directly with [[Amazon]]'s AWS. Azure becomes the second-largest cloud platform globally — and unlike AWS, Microsoft can bundle it with Office 365 and Windows Server, giving enterprise customers a single-vendor stack. - **June 13, 2016** — Acquires **LinkedIn for $26.2 billion** — Microsoft's largest acquisition at the time. LinkedIn gives Microsoft the professional identity layer for over 500 million workers (now 1B+). The data value: Microsoft knows where people work, what skills they have, who they know, and when they're looking for new jobs. This is structural power over the labor market, not just a social network. - **March 23, 2016** — **Tay chatbot launches on Twitter** — Microsoft's AI chatbot is designed to learn from conversations with users. Within hours, Twitter users teach Tay to produce racist, sexist, and genocidal statements. Microsoft takes Tay down within 16 hours. The episode is an early warning about AI alignment: a system that learns from unfiltered human input will learn the worst of human behavior. The lesson is not applied at scale until the ChatGPT safety debates of 2023–2024. - **June 4, 2018** — Acquires **GitHub for $7.5 billion** — the platform where the majority of the world's open-source and proprietary code is hosted. GitHub gives Microsoft structural control over the software development ecosystem. When Microsoft later integrates AI Copilot into GitHub, it embeds AI-assisted code generation into the workflow of tens of millions of developers worldwide. ## Era 8 — The OpenAI Bet (2019–2021) The Microsoft-[[OpenAI]] partnership is the most consequential corporate AI deal in history. See [[OpenAI Timeline]] for the full arc. - **July 22, 2019** — Microsoft invests **$1 billion in [[OpenAI]]**, beginning the partnership that will define both companies. The deal gives Microsoft exclusive cloud-provider rights (OpenAI runs on Azure) and commercial licensing for OpenAI's models. - **2020** — Azure revenues surpass $50 billion annually. Microsoft is now a cloud company that also sells software, not the other way around. - **January 2021** — Microsoft invests additional billions in [[OpenAI]]. The total investment eventually reaches approximately $13 billion, making Microsoft [[OpenAI]]'s largest investor and exclusive cloud partner. - **2021** — **JEDI cloud contract controversy**: after allegations that [[Donald Trump]] personally intervened to steer the $10 billion JEDI contract away from [[Amazon]] (to punish [[Jeff Bezos]] over [[Washington Post]] coverage), the [[Department of Defense]] cancels JEDI entirely. It is replaced by **JWCC (Joint Warfighting Cloud Capability)**, a multi-vendor contract split among Microsoft, [[Amazon]], [[Google]], and Oracle. Microsoft secures its position in the defense/intelligence infrastructure. - **January 18, 2022** — Microsoft announces acquisition of **Activision Blizzard for $68.7 billion** — the largest gaming acquisition in history. The [[FTC]] sues to block the deal, arguing it would give Microsoft unfair competitive advantage in gaming. The FTC loses in court; the deal closes in October 2023. The failure of the [[FTC]] challenge reinforces the pattern established by the 1998 [[Antitrust]] case: regulators identify market-concentrating acquisitions but lack the legal tools or political durability to stop them. ## Era 9 — AI Transformation (2022–2023) - **November 30, 2022** — **ChatGPT launches** ([[OpenAI]], powered by Microsoft Azure infrastructure). The product reaches 100 million users faster than any application in history. Microsoft's cloud infrastructure underlies every ChatGPT interaction. - **January 2023** — Microsoft confirms a **multibillion-dollar additional [[OpenAI]] investment**, bringing the total to approximately $13 billion. The deal gives Microsoft a 49% profit share, exclusive commercial licensing, and structural leverage over [[OpenAI]]'s direction. - **February 7, 2023** — **New Bing with ChatGPT integration** launches — Microsoft's attempt to use AI to disrupt [[Google]]'s search monopoly. Bing briefly becomes the most interesting product in tech. [[Google]] responds with Gemini, and the search market share barely moves — but the integration demonstrates Microsoft's vision of AI embedded in every product. - **March 16, 2023** — **Microsoft 365 Copilot announced** — an AI assistant embedded in Word, Excel, Outlook, PowerPoint, and Teams. The ambition: every knowledge worker interaction with Microsoft software will be AI-mediated. If it works, Microsoft captures the productivity gains from AI across the entire white-collar economy. - **November 17–21, 2023** — **The [[Sam Altman]] firing crisis**. [[OpenAI]]'s board fires Altman as CEO. Microsoft immediately offers to hire Altman and the entire [[OpenAI]] team. Nadella's move nearly breaks [[OpenAI]] apart — 700+ of 770 employees sign a letter threatening to leave for Microsoft. Within days, Altman is reinstated and the safety-focused board members who fired him are removed. The episode proves Microsoft's structural power: when [[OpenAI]]'s governance board tried to exercise oversight, Microsoft's economic leverage nullified them. Capital overrode governance. See [[OpenAI Timeline]]. ## Era 10 — Copilot, Consolidation, and the IBM Fear (2024) - **Early 2024** — **Microsoft 365 Copilot rolls out enterprise-wide**. Adoption is slower than Microsoft projected — enterprises struggle with data readiness, licensing costs ($30/user/month), and unclear ROI. The gap between AI hype and enterprise deployment becomes apparent. - **March 19, 2024** — Microsoft hires the **Inflection AI team**, including co-founder Mustafa Suleyman, who becomes CEO of a new Microsoft AI division. The move is strategic insurance: Microsoft is building in-house AI capabilities to reduce dependency on [[OpenAI]]. The message to [[Sam Altman]] is clear — Microsoft has alternatives. - **2024** — Microsoft briefly becomes the **world's most valuable company** at approximately $3.1 trillion market cap, surpassing Apple. The valuation is driven almost entirely by AI expectations — investors are betting that Microsoft's [[OpenAI]] partnership and Copilot integration will capture the productivity gains from AI across the global economy. - **2024** — The [[TikTok]] ban discussion resurfaces. Microsoft (with [[Walmart]]) had bid for TikTok's US operations in 2020 under [[Donald Trump]]'s first-term ban attempt. The bid failed, but it illustrated how "national security" concerns become business opportunities for well-connected companies. - **Internal tension**: Nadella is reportedly worried about "becoming [[IBM]] while [[OpenAI]] becomes the next Microsoft" — a historically literate fear. [[IBM]] dominated computing in the 1980s, outsourced the operating system to Microsoft, and never recovered. Microsoft is now in [[IBM]]'s position: dependent on a partner that could outgrow it. ## Era 11 — Current (2025–2026) - **January 2025** — [[Donald Trump]] says Microsoft is eyeing a [[TikTok]] bid again. The recurring pattern: Trump creates regulatory threat, then positions himself as dealmaker, with well-connected companies (Microsoft, Oracle) as potential beneficiaries. - **April 2026** — **Microsoft and [[OpenAI]] revise their partnership** — the new terms adjust revenue-share caps, remove exclusivity provisions, and allow [[OpenAI]] to distribute models across multiple cloud providers (not just Azure). Microsoft's fears about over-reliance on [[OpenAI]] are materializing: the partner is growing independent. - **May 2026** — Nadella testifies in the *[[Musk v. Altman]]* trial, revealing he worried about Microsoft "becoming the next [[IBM]]." Internal emails disclosed in the trial show Microsoft spent **$100 billion+** on [[OpenAI]] by June 2026. - **FY2025** — Revenue above $255 billion, market cap approximately $2.9 trillion. Copilot adoption remains below internal targets. Fortune reports "Microsoft lost its way in the AI race" — the narrative shifts from AI leader to AI spender. - **The current position**: Microsoft sits atop the most comprehensive infrastructure stack in technology — Windows (OS), Office/365 (productivity), Azure (cloud), LinkedIn (professional identity), GitHub (code), Xbox/Activision (gaming), and [[OpenAI]] integration (AI). But the [[OpenAI]] dependency creates existential risk: if [[OpenAI]] outgrows the partnership or a competitor's models surpass GPT, Microsoft's entire AI strategy rests on a foundation it doesn't control. --- ## RWKB Significance — Why This Matters [[Microsoft]] is the original tech monopoly story and the template for how technology companies interact with government power. Five structural patterns make it essential to the KB: **1. The [[Antitrust]] template.** The 1998–2001 Microsoft case is the foundational modern tech antitrust story. A federal judge found a monopoly, ordered a breakup, and an appeals court upheld the monopoly finding. Then a new administration — [[George W. Bush]]'s [[Department of Justice]] under John Ashcroft — simply dropped the breakup pursuit. The lesson: [[Antitrust]] enforcement against tech depends on political continuity that cannot be guaranteed across election cycles. Every subsequent case — [[Google]], [[Amazon]], [[Meta]] — has failed to get further. **2. The [[OpenAI]] kingmaker.** Microsoft's $13B+ investment gave it exclusive access to the most powerful AI models, embedded across products used by billions (Office, Azure, GitHub Copilot). When [[OpenAI]]'s safety board tried to exercise governance by firing [[Sam Altman]], Microsoft's economic leverage nullified them within days. The episode proved that in the AI era, capital overrides governance structures — even ones specifically designed to prevent exactly this scenario. **3. Government contract dependency.** JEDI, JWCC, Azure Government — [[Microsoft]] is deeply embedded in the defense and intelligence infrastructure alongside [[Amazon]]. Both companies need government contracts (multi-billion-dollar guaranteed revenue). The government needs their infrastructure (migration costs make switching nearly impossible). This mutual entanglement creates structural incentives for political compliance — the same dynamic documented in the [[Amazon Timeline]] and [[Defense Tech Timeline]]. **4. The [[IBM]] lesson.** Nadella's fear of "becoming [[IBM]]" is historically literate and structurally precise. [[IBM]] dominated computing, outsourced the OS to Microsoft, and never recovered. Microsoft is now in [[IBM]]'s position — dependent on a partner ([[OpenAI]]) that could outgrow it. The pattern: incumbent monopolists outsource a critical layer to a hungry startup, which then captures the value. **5. The infrastructure monopoly stack.** No company controls more of the digital workplace: Windows (1B+ devices), Office/365 (every enterprise), LinkedIn (1B+ professional profiles), GitHub (most of the world's code), Azure (second-largest cloud). Each layer reinforces the others and creates switching costs that make the whole stack nearly impossible to displace. Adding AI Copilot to every layer is an attempt to make the stack permanently indispensable.
