US v. Google redux: all the news from the ad tech trial

Here is a 197-word summary of the news article: On April 17th, 2025, a judge ruled that Google acted illegally to acquire and maintain monopoly power in online advertising. The US Department of Justice (DOJ) and Google are now returning to court to argue over whether this should lead to a Google breakup, forcing the company to sell its AdX ad exchange. The DOJ argued that Google unfairly dominated the market for ad tech tools used by publishers and advertisers. Google countered that it created efficient products and faced plenty of competition. The judge overseeing the case expressed reluctance to order a breakup, saying the case "ought to settle." Key points from the trial: - Experts warned that DOJ proposals to limit Google's ad tech could create major issues - Publishers and advertisers testified that they have no viable alternatives to Google's tools - The DOJ seeks to remove Google's "massive head start" in ad tech, while Google calls the proposals "radical and reckless" - Witnesses disagreed on how much of Google's ad tech a buyer should be able to own if a breakup occurs - Google muddied the waters about the feasibility of a breakup, but a DOJ witness said splitting up the tools is technically feasible.
