Overview
- A federal judge found Google unlawfully monopolized publisher ad servers and ad exchanges, violating U.S. antitrust law.
- The ruling stems from a 2023 lawsuit brought by the DOJ and multiple states, targeting Google's ad-tech practices.
- Judge Leonie Brinkema determined Google tied its publisher ad server and ad exchange through contracts and technology to suppress competition.
- The DOJ seeks to force Google to sell its Google Ad Manager suite, with a remedies phase to determine next steps.
- Google plans to appeal the decision, while a separate trial on the potential divestiture of its Chrome browser begins next week.
