US sues Google over its digital ad ‘dominance’
The US Department of Justice is suing Google for allegedly exercising monopolistic control of the digital advertising market, in the latest legal broadside against the group as Washington seeks to crack down on the dominance of Big Tech.
A complaint filed on Tuesday by the DoJ and a group of US states in a Virginia federal court accuses Google of using “anti-competitive, exclusionary, and unlawful means to eliminate or severely diminish any threat to its dominance over digital advertising technologies”.
It said “industry behemoth” Google had harmed competition in the ad tech sector “by engaging in a systematic campaign to seize control of the wide swath of high-tech tools used by publishers, advertisers, and brokers, to facilitate digital advertising”.
Authorities also accused Google of having “pervasive conflicts of interest” because it controls numerous aspects of the digital ad market, including the tech used by website publishers to sell ad space and the biggest exchange where ads are sold.
The US government has accused Google of violating the 1890 Sherman Antitrust Act, one of the country’s main corporate antitrust laws. It is seeking damages and also demanding that the company be forced to divest its Google Ad Manager suite.
Google did not immediately respond to a request for comment.
This is the first lawsuit against Google filed by the DoJ’s antitrust unit under the leadership of Jonathan Kanter, a critic of Big Tech who has prioritised cracking down on anti-competitive practices in the industry.
But Google is facing other legal challenges from the government brought under previous DoJ leadership. In 2020 the department sued the group for allegedly suppressing competition in internet search, seen as the government’s most high-profile antitrust move since its lawsuit against Microsoft in the 1990s.
