Google acted illegally to maintain a monopoly in some online advertising technology, a federal judge ruled on Thursday, adding to legal troubles that could reshape the $1.88 trillion company and alter its power over the internet.
Judge Leonie Brinkema of the U.S. District Court for the Eastern District of Virginia said in a ruling that Google had broken the law to build its dominance over the largely invisible system of technology that places advertisements on pages across the web. The Justice Department and a group of states had sued Google, arguing that its monopoly in ad technology allowed the company to charge higher prices and take a bigger portion of each sale.
Google has increasingly faced a reckoning over the dominant role its products play in how people get information and conduct business online. Another federal judge ruled in August that the company had a monopoly in online search. He is now considering a request by the Justice Department to break the company up.
Judge Brinkema, too, will have an opportunity to force changes to Google’s business. In its lawsuit, the Justice Department pre-emptively asked the court to force Google to sell some pieces of its ad technology business acquired over the years.
