Federal Judge Rules Google Illegally Monopolized Ad Tech Markets

The ruling allows U.S. prosecutors to seek the breakup of Google's advertising business, with hearings on potential remedies to follow.

Overview

  • Judge Leonie Brinkema found Google violated antitrust laws by monopolizing the publisher ad server and ad exchange markets.
  • The court determined Google unlawfully tied its publisher ad server and ad exchange, harming competition and consumers.
  • The Department of Justice is pushing for Google to divest its Google Ad Manager, which includes the publisher ad server and ad exchange.
  • Google plans to appeal the decision, arguing it won part of the case as claims of monopoly in advertiser ad networks were dismissed.
  • A separate trial next week will address the DOJ's request for Google to sell its Chrome browser to address dominance in online search.
