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.

"Today’s lawsuit from the DOJ attempts to pick winners and losers in the highly competitive advertising technology sector,” a Google spokesperson told Engadget. “It largely duplicates an unfounded lawsuit by the Texas Attorney General, much of which was recently dismissed by a federal court. [The] DOJ is doubling down on a flawed argument that would slow innovation, raise advertising fees, and make it harder for thousands of small businesses and publishers to grow."
