Nine additional US states join lawsuit against Google's ad tech.

Nine more US states, including Michigan and Nebraska, have joined the Department of Justice's lawsuit against Google, alleging that the company broke antitrust law in running its digital advertising business. The government argues that Google should be forced to sell its ad manager suite because it illegally abused its dominance of online advertising. Google denies any wrongdoing and has asked the judge to dismiss the lawsuit. The Justice Department's ad tech lawsuit followed a separate lawsuit filed in 2020 that accused Google of violating antitrust law to maintain its dominance in search.
