In a significant ruling, a federal judge has determined that Google holds an illegal monopoly in the online advertising market, marking a troubling development for the tech giant. This decision, described as a crucial moment for antitrust efforts, suggests that the company has unlawfully dominated the ad tech sector to the detriment of competitors and consumers. The ruling opens the door for potential breakup proceedings, prompting discussions on the future of Google and its vast advertising network. Legal experts note that this second ruling against Google within a year may accelerate efforts to dismantle its monopolistic practices, further reshaping the digital advertising landscape.
