Google is facing a significant antitrust trial led by the U.S. Department of Justice, accusing the tech giant of monopolizing the online advertising market by using anti-competitive practices. At the center of the case is Google Ad Manager, a platform that allegedly consolidates Google's control over publisher ad servers and ad exchanges, making it difficult for rivals to compete. Prosecutors have presented evidence, including statements from former Google executives, that suggest the company aimed to 'crush' competition. Google denies these allegations, arguing it faces substantial competition from other tech companies like Meta, Amazon, and Apple. The outcome of this trial could lead to the breakup of Google's ad tech business, significantly impacting its $200 billion advertising revenue. The case is being closely watched as it could set a precedent for future regulatory actions against Big Tech.
