EU antitrust regulators opened on Friday an investigation into Alphabet unit Google and Facebook’s online display advertising services deal to check if it violates the bloc’s competition rules. The European Commission said the investigation will focus on a 2018 deal between Facebook and Google dubbed Jedi Blue that may thwart ad tech rivals and restrict competition. “Via the so-called ‘Jedi Blue’ agreement between Google and Meta, a competing technology to Google’s Open Bidding may have been targeted with the aim to weaken it and exclude it from the market for displaying ads on publisher websites and apps,” European antitrust chief Margrethe Vestager said in a statement.
