The European Commission has fined Google nearly $3.5 billion for abusing its dominance in digital advertising by unfairly favoring its ad exchange, AdX. Regulators mandated the company cease these practices within 60 days, citing severe ‘inherent conflicts of interest’ in the adtech supply chain. Teresa Ribera, executive vice president, emphasized the need for fair digital markets, warning of more potent actions if Google fails to comply. Google plans to appeal the ruling.
