The ongoing antitrust trial against Google has seen YouTube CEO Neal Mohan testify that the company's success in digital advertising is due to innovation, not monopolistic practices. The U.S. Department of Justice (DOJ) alleges that Google has built a dominant position through predatory acquisitions, including DoubleClick and Admeld, effectively 'parking' competitors to eliminate threats. Mohan countered that Google's growth is a reflection of the expanding ad industry rather than monopolistic behavior, and emphasized the competition Google faces in the ad tech market. The trial's focus on the term 'parking' relates to accusations that Google buys rivals to neutralize competition. As the trial progresses, the DOJ continues to argue that Google's control over the ad tech ecosystem harms both advertisers and publishers by driving up prices. The outcome of the trial could lead to significant repercussions for Google's operations in the digital advertising space.
