US government seeks breakup of Google's ad tech business

The US Justice Department is seeking a court-ordered breakup of Google’s advertising technology business after a judge determined the company had illegally monopolized key parts of the digital ad market. The government specifically targets Google’s ad exchange and publisher ad server, arguing that Google’s dominance leaves most publishers dependent on its technology and stifles competition. Prosecutors contend that behavioral changes are insufficient and that only divestiture can prevent Google from finding new ways to maintain its monopoly. Google opposes the proposed breakup, arguing it is impractical, would harm publishers, and lacks legal precedent, instead offering to modify certain business practices. A further hearing is scheduled for September, where detailed arguments about possible remedies will be presented. This effort follows a separate antitrust case in which the DOJ is also seeking the divestment of Google’s Chrome browser.
