Microsoft Monopoly Case Study
Defining the relevant market

Other forms of operating systems - such as those used in hand-held computers, Apple Macintoshes, network computers connected to other machines, or servers for hosting Internet sites - were judged by the courts to constitute separate markets and thus to offer no competition.

In addition, Microsoft sought to make deals both with computer manufacturers and with online services like AOL to offer Internet Explorer with their products, sometimes exclusively, and it prevented manufacturers from deleting Microsoft's browser even when they also installed Netscape's. In short, it threw its weight
