U.S. Sues Google Over Alleged Advertising Monopoly—Latest Tech Antitrust Suit



The Department of Justice and eight states filed a lawsuit against Google on Tuesday, claiming the tech giant abuses its monopoly on online advertising technology and has stifled its competition through a series of acquisitions—the latest in a series of antitrust suits against Google and other large tech companies.

Key Facts

In the suit, filed in federal court in Virginia, the Justice Department alleges Google has “corrupted legitimate competition” in the online ad space through a “systematic campaign to seize control of” online tools used to facilitate advertising.

Specifically, the suit alleges Google has purchased its ad tech competitors and continues to “wield its dominance” online, forcing advertisers to use the site and “disrupting their ability to use competing products effectively.”

Google’s alleged monopoly creates disadvantages for website publishers and other online advertisers “who dare to use competing ad tech products” for “higher quality or lower cost matches,” according to the suit.

The suit, filed by the DOJ along with California, Colorado, Connecticut, New Jersey, New York, Rhode Island, Tennessee and Virginia, violated the federal Sherman Act—which prohibits monopolization and the attempt or conspiracy to monopolize—and seeks to break up the company’s ad tech service by forcing it to shed some of its ad business.


Google did not immediately respond to a request for comment from Forbes, though the company has denied previous accusations that it had monopolized the digital ad space, as well as an earlier antitrust complaint that it cut out rivals through its search engine. Google argued in late 2020 that its ad tech prices had fallen in recent years, which it called “the hallmarks of a highly competitive industry.”

Crucial Quote

“Google, a single company with pervasive conflicts of interest, now controls the technology used by nearly every major website publisher to offer advertising space for sale, the leading tools used by advertisers to buy that advertising space, and the largest ad exchange that matches publishers with advertisers each time that ad space is sold,” according to the suit.

Key Background

The lawsuit is the second filed by the DOJ against Google. An October 2020 suit filed under the Trump Administration claimed Google had violated antitrust law by stunted competition in internet searches through a series of “exclusionary practices” that have been “harmful to competition.” That case is set to go to trial in September.


Shares of Google parent company Alphabet have fallen nearly 1.2% on the day, decreasing to $98.63 as of 2 p.m. The company’s share price has taken a major hit since peaking at $148.93 in November 2021, part of a broader decline in tech stocks.
