Judge rules google Held Monopoly Over Online ad Technology
In a notable blow to the tech giant, a U.S. federal judge has ruled that Google illegally monopolized aspects of the online advertising technology market. This decision follows a previous ruling last year that found Google to be a monopoly in the online search market, potentially leading to further business divisions for the company.

Judge Leonie Brinkema of the Eastern District of Virginia issued the ruling Wednesday, stating that Google violated antitrust laws related to advertising servers and exchanges in three specific areas of advertising technology. The lawsuit, initiated against Google on April 17, alleged anti-competitive practices in the technical market.
Details of the Court’s Findings
The court determined that Google holds a dominant position in the exchange market, which facilitates the buying and selling of advertising space, and in the advertising server market, which aids websites in managing and displaying advertisements. The ruling specifically noted that Google maintained its dominance by preventing publishers – the media outlets offering ad space – from utilizing competing advertising servers, thereby hindering real-time bidding on ad exchanges.
Though, the court rejected the Justice Department’s claim that Google monopolized the advertising network market, were advertisers and publishers are connected.
Justice Department’s Lawsuit and potential Remedies
The ruling stems from a lawsuit filed by the U.S. Department of Justice (DOJ) in January 2023, accusing Google of monopolizing advertising-related technology and abusing its market power to stifle competition within the advertising technology industry. Following the ruling’s confirmation, the court will consider potential corrective actions against Google, including the possibility of ordering the company to divest parts of its business. The DOJ had previously suggested that Google should sell Google Ad Manager, a key component of its advertising network division.
The DOJ asserts that Google controls approximately 90% of the publisher advertising server market, exerting significant influence over online advertising spaces, including those on media and news websites. Google reportedly charges between 20% and 30% of advertising costs as platform usage fees. During the trial, testimony indicated that Google’s dominant position makes it virtually impossible for entities to utilize alternative online advertising services.
Google’s Response and Planned Appeal
Google has announced its intention to appeal the ruling. “We’ve won half of this litigation and the other half will appeal,” the company stated. Google also expressed disagreement with the ruling concerning publisher tools, asserting that “Publishers have a variety of options, and Google’s advertising technology tools are simple, inexpensive and effective.”
Publishers have a variety of options, and Google’s advertising technology tools are simple, inexpensive and effective.
Broader Antitrust Concerns for Google
This antitrust setback adds to Google’s existing challenges. The company previously lost an antitrust lawsuit related to the online search market and faces the potential forced sale of its Chrome browser, a core business asset. Hearings regarding the resolution of the search market monopoly are scheduled to begin on April 21.
