On Thursday, a federal judge ruled that Google violated antitrust laws and illegally monopolized the online ad tech industry. In 2023, Google made $237.9 billion from advertising revenue, far more than competitors like Microsoft and Baidu. The Justice Department and a group of states joined together to sue Google in this case.

A landmark court ruling in the U.S. sets the stage for a global reckoning with Google’s role in the digital economy.
