The Department of Justice (DOJ) has filed a second antitrust lawsuit against Google, accusing the tech giant of using its dominance in the online advertising market to stifle competition.

The lawsuit claims that Google has used its market power to maintain its monopoly in the online search and advertising markets, and to control pricing in the online ad market.

The DOJ is seeking to break up Google’s ad business and to restore competition in the online advertising market.

The lawsuit follows an earlier antitrust suit filed by the DOJ in October 2020, which accused Google of using its dominance in the online search market to give its own products an unfair advantage over competitors.

In its latest lawsuit, the DOJ alleges that Google has used its market power to limit competition in the online ad market by controlling the technology used by other companies to buy and sell ads.

The DOJ is also seeking to prevent Google from using its market power to restrict access to its advertising technology.

The lawsuit is the latest in a series of antitrust actions taken by the DOJ against tech companies. The DOJ has previously filed antitrust lawsuits against Apple, Facebook, and Amazon.

Google has denied the allegations, saying that its ad business benefits consumers and that its technology is open and competitive.

The case is expected to be a long and complicated one, and could have significant implications for the future of the online advertising market.
