The Justice Department will file an antitrust lawsuit Tuesday alleging that Google engaged in anticompetitive conduct to preserve monopolies in search and search-advertising that form the cornerstones of its vast conglomerate, according to senior Justice officials.
The long-anticipated case, expected to be filed in a Washington, D.C., federal court, will mark the most aggressive U.S. legal challenge to a company’s dominance in the tech sector in more than two decades, with the potential to shake up Silicon Valley and beyond. Once a public darling, Google attracted considerable scrutiny over the past decade as it gained power but has avoided a true showdown with the government until now.
Google owns or controls search distribution channels accounting for about 80% of search queries in the U.S., the officials said. That means Google’s competitors can’t get a meaningful number of search queries and build a scale needed to compete, leaving consumers with less choice and less innovation, and advertisers with less competitive prices, the lawsuit will allege.
