Microsoft Antitrust Case: Monopoly, Litigation, and Outcomes
This paper provides a comprehensive overview of the antitrust case brought by the U.S. Department of Justice against Microsoft Corporation in the late 1990s. Beginning with Microsoft's founding and its rise to dominance in PC operating systems and applications, the paper traces the government's four-count complaint under the Sherman Act, including allegations of illegal tying, monopolization, and exclusionary agreements. It examines Judge Thomas Penfield Jackson's findings of fact, his order to break up the company, and the eventual reversal on appeal. The paper concludes with an account of the settlements Microsoft reached with the DOJ, state attorneys general, and private plaintiffs, as well as the company's attempts to rehabilitate its public image.

What makes this paper effective
- The paper grounds legal arguments in concrete historical context by tracing Microsoft's origins before analyzing antitrust violations, giving readers the background needed to evaluate the allegations fairly.
- It quotes the four Sherman Act counts verbatim, allowing the legal claims to speak for themselves rather than relying solely on paraphrase.
- The chronological structure is tight and purposeful, moving from corporate founding through litigation to settlement without unnecessary digressions.
Key academic technique demonstrated
The paper demonstrates effective use of primary legal source material — including the court's "findings of fact" and the specific counts of the complaint — integrated with secondary business and technology history. This mixed-source approach grounds abstract legal concepts (such as barriers to entry and the "vicious circle" of network effects) in real market dynamics that a general reader can follow.
Structure breakdown
The paper opens with the government's allegations and the relevant consent decree, then pivots to a historical narrative of Microsoft's founding and growth. A middle section analyzes the competitive strategies that led to dominance, followed by a detailed account of the trial and Judge Jackson's ruling. The paper closes by covering the appellate reversal, successive settlements, and Microsoft's evolving public relations strategy — a structure that moves logically from cause to consequence.
Introduction: Government Allegations Against Microsoft
Issues in antitrust cases tend to be very complex and technical, but in the case of the government versus Microsoft, they are quite understandable. The government alleged that Microsoft used predatory pricing tactics to destroy competitors and eliminate competition in the marketplace. The company was also accused of erecting technical barriers within its operating systems to make it difficult or impossible for non-Microsoft software to run on Windows. In 1993, the Department of Justice (DOJ) began an investigation into these practices, which resulted in a consent decree on July 15, 1994, in which Microsoft agreed that it would not tie other Microsoft products into its Windows operating system.
In the late 1990s, Microsoft began bundling its Internet Explorer web browser into Windows and soon acquired a dominant position in the browser market. As a result, an antitrust case was brought against Microsoft in October 1997. The four counts filed against Microsoft were:
Count 1: "Unlawful Exclusive Dealing and Other Exclusionary Agreements in Violation of Section 1 of the Sherman Act.... Microsoft's agreements with ISPs, ICPs, and... OEMs... unreasonably restrict competition... thereby restraining competition in the Internet browser market..."
Count 2: "Unlawful Tying in Violation of Section 1 of the Sherman Act.... Microsoft has tied... its Internet browser to its separate Windows operating system..."
Count 3: "Monopolization of the PC Operating Systems Market in Violation of Section 2 of the Sherman Act.... Microsoft possesses monopoly power in the market for PC operating systems.... Microsoft has willfully maintained, and unless restrained by the Court will continue to willfully maintain, that power by anticompetitive and unreasonably exclusionary conduct. Microsoft has acted with an intent illegally to maintain its monopoly power in the PC operating system market, and its illegal conduct has enabled it to do so..."
Count 4: "Attempted Monopolization of the Internet Browser Market in Violation of Section 2 of the Sherman Act."
