EU Investigates Google’s Advertising Business

The European Union announced Tuesday it is once again investigating Google for what could be anti-competitive activities in digital advertising.

The investigation will try to determine if Google is harming competitors by restricting third party access to user data that could better target advertising. "We are concerned that Google has made it harder for rival online advertising services to compete in the so-called ad tech stack," European Competition Commissioner Margrethe Vestager said in a statement. Google said it would cooperate in the investigation.
