A federal judge has ruled that Google is a monopolist in certain parts of the online advertising market, marking the second time within a year that the tech giant has been found in violation of U.S. antitrust laws. Judge Leonie Brinkema from the U.S. District Court for the Eastern District of Virginia determined that Google unlawfully monopolized parts of its advertising technology business to dominate the programmatic ad market, which is a significant revenue source for the company. The ruling could lead to penalties impacting billions in revenue generated from ads on various apps and websites. The decision follows a similar ruling last August, where a judge found Google maintained an illegal monopoly in search. The Department of Justice and multiple states initially filed the suit in January 2023, alleging Google’s anticompetitive practices in the advertising sector. While the court did not find Google monopolized the market for advertiser ad networks, it did rule against its dominance in publisher tools. Google’s vice president of regulatory affairs, Lee-Anne Mulholland, stated that the company plans to appeal the ruling on publisher tools, arguing that its ad tech tools are popular due to their simplicity and effectiveness. The Department of Justice sees this ruling as a significant victory for antitrust enforcement and the open internet.
