A U.S. federal judge has ruled that Google has illegally monopolized the online advertising technology market, marking a significant victory for the Department of Justice in its antitrust case against the tech giant. The ruling found that Google willfully acquired and maintained monopoly power in the markets for publisher ad servers and ad exchanges. The Department of Justice, along with a coalition of states, argued that Google’s dominance forced advertisers and publishers to incur higher costs while allowing Google to take a larger share of each transaction. The ruling paves the way for potential divestitures, such as the sale of Google’s Ad Manager, which includes its publisher ad server and ad exchange. Google plans to appeal the decision, contending that the case focused on past behaviors and overlooked competition from other tech companies.
