Microsoft Antitrust Case: Monopoly, IE, and the Sherman Act
This paper examines Microsoft's high-profile antitrust disputes with the U.S. Department of Justice, focusing on the company's alleged abuse of market power through the bundling of Internet Explorer with its Windows operating system. It reviews the conditions that define monopoly, the government's role in regulating anticompetitive behavior, and the specific charges brought under Section 2 of the Sherman Act. The paper also considers how Microsoft's conduct affected competition in the browser market, the concept of rent-seeking behavior, and how evolving internet access and mobile operating systems eventually eroded Microsoft's dominant market position.

What makes this paper effective
- Grounds the Microsoft case study in foundational economic concepts — monopoly conditions, deadweight loss, barriers to entry, and rent-seeking — before applying them to the specific antitrust dispute.
- Uses direct citations from primary legal and journalistic sources (the DOJ conclusions of law, The Washington Post, The Seattle Times) to anchor its claims about the charges Microsoft faced.
- Concludes by contextualizing the case historically, noting how market forces (faster internet, mobile operating systems) ultimately achieved some of what regulatory intervention sought.
Key academic technique demonstrated
The paper demonstrates applied economic analysis: it introduces abstract concepts (deadweight loss, rent-seeking, barriers to entry) and then maps each concept directly onto real-world corporate behavior and legal outcomes. This technique shows the reader not just what happened, but why it mattered economically.
Structure breakdown
The paper opens with a theoretical framework defining monopoly and government regulation, then transitions into the Microsoft case history, followed by the specific legal charges under the Sherman Act, and closes with analysis of market effects and the broader resolution of the situation. Each section builds logically on the last, moving from theory to application to outcome.
Introduction to Monopoly Conditions
Monopoly conditions can be defined by an array of circumstances that a company can find itself in when it lacks any reasonable competition. These conditions can manifest in a variety of ways, and in some cases it is only reasonable to have one company provide goods or services — such as utilities or internet access — because these services require massive infrastructure investments that create barriers to entry for other firms in the market. Many of these institutions are regulated by the government to ensure that prices are not raised to an extent that they create a large deadweight loss to society — that is, a price higher than the market equilibrium at which marginal revenues equal marginal costs. In the event that a monopoly situation arises, the government can intervene in its operations to attempt to remedy the negative consequences.
Microsoft's Market Position and Antitrust History
One of the best examples of potential antitrust violations and investigations in recent decades can be illustrated by Microsoft's market position. Microsoft spent 21 years — more than half its lifetime — fighting antitrust battles with the U.S. government, waging one of the biggest monopoly disputes in the country's history (Chan, 2011). The company was nearly split up in the early 2000s because its operating system provided an unfair advantage in the web browser industry. Since Microsoft Windows is the world's most popular operating system for personal computers, software bundled with the system would be automatically available to users. This meant that Microsoft's browser, Internet Explorer, held an unfair advantage over competitors such as Netscape — a position that was argued to constitute an unlawful advantage in the market.
Department of Justice Charges and the Sherman Act
The United States Department of Justice concluded that Microsoft was abusing its market power — on grounds other than price — through its inclusion of the Internet Explorer (IE) web browser in its operating system. In 1994, Microsoft Corporation was sued by the Department of Justice on behalf of the United States for violating §2 of the Sherman Antitrust Act "…by engaging in monopolization through a series of exclusionary and anticompetitive acts designed to maintain its monopoly power" (The Washington Post, 2000). Furthermore, the company was charged with, among other things: (1) attempting to monopolize the web browser market; (2) tying its Internet Explorer browser application to its Windows operating system; and (3) "unlawfully maintaining a monopoly in the operating system market through anticompetitive terms in its licensing and software developer agreements."
Conclusion: Competition and the Changing Landscape
Although Microsoft did not gain any direct economic profits from the sale of its web browser, it leveraged its market power to eliminate competition in a way that served its broader commercial interests. This makes the case a notable and instructive example in antitrust law. Ultimately, technological change — faster internet access and the rise of mobile platforms — accomplished much of what regulatory intervention had sought to achieve, restoring a competitive environment in both the browser and operating system markets.
