DOJ, 8 States Sue Google Over Its Online Ad Business

The Justice Department is seeking the breakup of Google’s business brokering digital advertising across much of the internet, a major expansion of the legal challenges the company faces to its business in the U.S. and abroad.

A lawsuit filed Tuesday, the Justice Department’s second against the Alphabet Inc. unit following one filed in 2020, alleges that Google abuses its role as one of the largest brokers, suppliers and online auctioneers of ads placed on websites and mobile applications. The filing promises a protracted court battle with wide-ranging implications for the digital-advertising industry.

Filed in federal court in Virginia, the case alleges that Google abuses monopoly power in the ad-tech industry, hurting web publishers and advertisers that try to use competing products. Eight states, including California and New York, joined the Justice Department’s lawsuit.

The lawsuit asks the court to unwind Google’s “anticompetitive acquisitions,” such as its 2008 purchase of ad-serving company DoubleClick, and calls for the divestiture of its ad exchange.

“For 15 years Google has pursued a course of anticompetitive conduct that has allowed it to halt the rise of rival technologies, manipulate auction mechanics, insulate itself from competition, and forced advertisers and publishers to use its tools,” Attorney General Merrick Garland said at a press conference Tuesday. “Google has engaged in exclusionary conduct that has severely weakened if not destroyed competition in the ad-tech industry.”

A Google spokesman said the lawsuit “attempts to pick winners and losers in the highly competitive advertising technology sector.”

“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,” the spokesman said.
