The Justice Department is suing Google to break up its ad business

Alongside eight states, the US Department of Justice is suing Google to break up the company’s advertising business. In a complaint filed Tuesday with a federal court in Virginia, the agency accused Google of illegally monopolizing the digital advertising market. “Google’s anticompetitive behavior has raised barriers to entry to artificially high levels, forced key competitors to abandon the market for ad tech tools, dissuaded potential competitors from joining the market, and left Google’s few remaining competitors marginalized and unfairly disadvantaged,” the Justice Department alleges.
