Google is facing another significant antitrust trial in Virginia, focusing on its alleged monopoly over online advertising technology. Regulators argue that Google dominates the ad tech market by controlling both the buy and sell sides, enabling it to keep a significant portion of advertising revenue. Prosecutors claim this monopoly harms publishers and advertisers by inflating costs and limiting competition. Google, however, denies these allegations, arguing that it operates in a competitive market and provides superior services. The case, which follows a recent ruling declaring Google's search engine an illegal monopoly, could lead to substantial changes in Google's business practices and impact the broader digital advertising industry. The outcome is closely watched by major publishers and other stakeholders who rely on digital ad revenue.
