Google must break up digital ad business over competition concerns, European regulators say

$Alphabet-C(GOOG.US)$ $Alphabet-A(GOOGL.US)$ European Union antitrust regulators took aim at Google's lucrative digital advertising business in an unprecedented decision, saying Wednesday that the tech giant must sell off some of its ad business to address competition concerns.
The European Commission, the bloc's executive branch and top antitrust enforcer, said its preliminary view after an investigation is that “only the mandatory divestment by Google of part of its services” would satisfy the concerns.
The 27-nation EU has led the global movement to crack down on Big Tech companies — including groundbreaking rules on artificial intelligence — but it has previously relied on issuing blockbuster fines, including three antitrust penalties for Google worth billions of euros (dollars).
