EU Regulators Open Antitrust Probe of Google's Online Ad Business

European Union regulators took aim at the heart of Google’s business model, announcing that the Silicon Valley giant is the subject of a new antitrust investigation for potentially abusing its dominance in the online advertising market to stifle competition. The investigation is part of a broader push by the European authorities to clamp down on the world’s largest technology companies. Amazon, Apple and Facebook are also the subject of antitrust actions by the 27-nation bloc, and the European Union is drafting new antitrust and digital services laws to further tighten oversight of Big Tech.
