The U.S. Department of Justice previously accusedGoogle's advertising technology affects market competition, but after the court found the evidence insufficient, Judge Leonie Brinkema of the U.S. District Court for the Eastern District of Virginia ruled that GoogleThere is obvious violation of the law and constitutes market monopoly.
Leonie Brinkema pointed out that in order to maintain its technological leadership in online advertising, Google not only affects its competitors' fair competition in the market, but also affects Google's partners' opportunities to expose their advertising content on more platforms, making it difficult for consumers to see appropriate advertising content through online platforms.
The U.S. Department of Justice first filed a lawsuit against Google in January 2023. Earlier, it determined that Google violated market monopoly with its services and required it to split off its Chrome browser business.
Regarding Google's monopoly in the online advertising market, Judge Leonie Brinkema originally ruled that the US Department of Justice must present testimony from advertisers who were substantially affected. However, the judge later accepted the US Department of Justice's claim that Google has a market monopoly of up to 87% in advertising sales technology, and that it requires advertisers to use its software services with this monopoly ratio, resulting in advertisers and content platform operators having almost no other options for advertising exposure.
The court has ruled that Google's advertising business involves a monopoly, so the US Department of Justice will use this as an excuse to ask the court to rule that Google must split its advertising technology business, but the specific outcome may still depend on the final ruling of the court.
