A judge ruled Google broke antitrust law, then let it keep its entire ad-tech business
A judge ruled Google violated antitrust law but allowed it to keep its ad-tech business. The order requires Google to make its systems interoperable with rivals, share more auction data, and appoint a compliance monitor. The Justice Department sought a breakup, but the judge deemed it unnecessary. Google's ad-tech business generated $30B in 2023, though revenue has declined for 16 quarters.
