United States v. Microsoft Corp.
The road to the antitrust trial ran through a decade of escalating scrutiny. The Federal Trade Commission opened an inquiry in 1990 into whether Microsoft was abusing its PC operating-system monopoly, deadlocked two-to-two in 1993, and closed the file; the Department of Justice under Janet Reno then opened its own investigation, producing a July 15, 1994 consent decree in which Microsoft agreed not to tie other products to Windows sales but remained free to integrate additional features into the operating system. That distinction became the battlefield: Microsoft insisted Internet Explorer was not a product but a feature it was allowed to add, while the government disagreed. With more than ninety percent of workplace PCs running its systems, Microsoft's licensing restrictions on manufacturers, its treatment of rival browsers, and its manipulation of application programming interfaces drew the government's case that bundling had unlawfully foreclosed competitors.
