1. **Founding and Early Vision**: Childhood friends Bill Gates and Paul Allen, passionate programmers, launched Traf-O-Data in 1972, selling a rudimentary computer to track traffic data. This foreshadowed their future.
A pivotal moment came with the January 1975 Popular Electronics, featuring MITS’s Altair 8800 microcomputer. Inspired, Allen proposed they program a BASIC interpreter. Gates swiftly contacted MITS, falsely claiming a working interpreter, leading to a demonstration. Allen built an Altair simulator while Gates developed the interpreter, which performed flawlessly for MITS in March 1975.
MITS agreed to distribute their creation as Altair BASIC. Microsoft was established on April 4, 1975, with Gates as CEO. Allen suggested “Micro-Soft.” By August 1977, an agreement with ASCII Magazine in Japan led to its first international office. The company moved headquarters to Bellevue, Washington, in January 1979.
2. **Dominance in Operating Systems: MS-DOS and Early Windows**: Microsoft entered the operating system (OS) business in 1980 with Xenix, its Unix version. However, a crucial IBM contract in November 1980 for a CP/M OS version for the IBM Personal Computer truly propelled its dominance, offering an unparalleled platform.
To fulfill the IBM contract, Microsoft purchased 86-DOS, a CP/M clone, from Seattle Computer Products. Rebranded MS-DOS, IBM also used it as IBM PC DOS. Microsoft retained full MS-DOS ownership after the IBM PC’s August 1981 release. IBM copyrighted its PC BIOS, but OS restrictions were absent, allowing Microsoft to become the leading PC OS vendor.
Beyond core software, Microsoft diversified, releasing the Microsoft Mouse in 1983, its first significant hardware foray. It also established Microsoft Press. Paul Allen resigned in 1983 due to Hodgkin’s lymphoma, later recounting a dispute with Gates over share dilution. Allen pursued diverse investments.
3. **The Groundbreaking IPO and Wealth Creation**: Microsoft’s foundational years culminated in its Initial Public Offering (IPO). On February 26, 1986, Microsoft relocated its headquarters from Bellevue to the larger Redmond, Washington, campus, symbolizing escalating growth. This new base became synonymous with the tech giant.
On March 13, 1986, Microsoft officially went public on the NASDAQ exchange. The IPO was a profound economic event, generating immense wealth for early investors and employees.

On July 27, 1994, the Department of Justice’s Antitrust Division alleged “anti-competitive per processor licenses” from 1988-1994. These required OEMs to pay royalties regardless of Microsoft OS installation, effectively acting “as a penalty, or tax, on the OEM’s use of a competing PC operating system.” In October 1997, Justice moved to stop Internet Explorer bundling with Windows, asserting a 1994 agreement violation.
The United States v. Microsoft Corp. judgment on April 3, 2000, labeled the company an “abusive monopoly,” leading to a 2004 settlement. Internationally, the European Union’s March 2004 antitrust action for abusing Windows OS dominance resulted in a €497 million ($613 million) judgment, mandating Windows XP versions without Media Player. Further EU fines of €899 million ($1.4 billion) in February 2008 for non-compliance, citing unreasonable server information prices. Microsoft asserted these were “past issues that have been resolved.”
7. **Bill Gates’ Transition and Steve Ballmer’s Era**: A significant leadership transition occurred January 13, 2000: Bill Gates stepped down as CEO, passing the role to Steve Ballmer. Gates, however, remained deeply involved as Chief Software Architect, focusing on technological vision.
