The US government asked a federal judge on Friday to order the breakup of Google’s digital advertising business, arguing that the tech giant’s pledges to change its practices cannot be trusted.Government lawyers made their case in closing arguments of a lawsuit focused on Google’s ad tech “stack” the suite of tools that website publishers use to sell ads and advertisers use to buy them.
This marks a second major antitrust test for Google this year.In September, a judge rejected a similar Department of Justice demand to break up the California-based tech giant’s world-dominating search engine business.
These cases are part of a broader US government effort to curtail the competitive dominance of big tech companies, including Apple, Amazon and Meta.Results have been mixed so far another judge decided against government lawyers in a suit against Meta’s social media empire earlier this week.
In a brief filed ahead of Friday’s arguments, the DOJ and multiple US states accused Google of illegally acquiring monopolies in two interconnected advertising technology markets through a “decade-long campaign of ever-mutating unlawful conduct.”
The government’s case portrays Google as simultaneously controlling multiple sides of the digital advertising marketplace owning the platform that publishers use to sell ads, the exchange where transactions occur, and commanding huge advertiser demand.
According to the DOJ, Google once compared this arrangement to Goldman Sachs owning the New York Stock Exchange.
“We are here to fix the problem. We will argue that the best solution is to break up Google’s monopoly, which will create a new competitor,” Assistant Attorney General Gail Slater said in a post on X.Google has pushed back, characterizing the proposed remedies as extreme government overreach that would harm publishers, advertisers and consumers.
