7.7: Network Effects and Antitrust Law

Regulating digital monopolies remains a complex challenge. U.S. antitrust law has traditionally focused on consumer harm, yet many digital platforms offer “free” services, lower prices, and enhanced functionality, complicating conventional assessments of market dominance. Technology companies often argue that competition is only “one click away” and that network effects—while powerful—ultimately benefit users by improving connectivity and efficiency. The Microsoft antitrust case is frequently cited in this context: despite government intervention, it was market innovation—most notably the rise of Google—that ultimately reshaped the competitive landscape.

At the same time, scholars and journalists emphasize that antitrust action can serve as a catalyst for innovation. Charles Duhigg (2019) observes that the Microsoft case inadvertently opened space for new entrants such as Google to emerge. Similarly, Wall Street Journal columnist Greg Ip (2017) argues that regulatory intervention may at times be necessary to dismantle entrenched monopolies and restore competitive conditions. Whether today’s technology giants maintain their dominance or yield to new competitors will depend on the interplay of policy decisions, technological innovation, and public will.
