BRUSSELS (AP) 鈥� European Union regulators hit Google with fresh antitrust charges Wednesday, saying the only way to satisfy competition concerns about its lucrative digital ad business is by selling off parts of .
The unprecedented decision to push for such a breakup marks a significant escalation by Brussels in its crackdown on Silicon Valley digital giants.
The European Commission, the bloc's executive branch and top antitrust enforcer, said its preliminary view after an investigation is that 鈥渙nly the mandatory divestment by Google of part of its services鈥� would satisfy the concerns.
The 27-nation EU has led the global movement to companies 鈥� including groundbreaking 鈥� but it has previously relied on issuing blockbuster fines, including three antitrust penalties for Google worth billions of euros (dollars).
It's the first time the bloc has told a tech giant that it should split up key parts of its business over violations of the EU's strict antitrust laws, though details on what that could look like are not clear following the preliminary finding.
Google can now defend itself by making its case before the commission issues its final decision. The company said it disagreed with the decision and 鈥渨ill respond accordingly,鈥� adding that the EU鈥檚 investigation focusing on a narrow part of its ad business.
鈥淥ur advertising technology tools help websites and apps fund their content, and enable businesses of all sizes to effectively reach new customers," said Dan Taylor, Google vice president of global ads. "Google remains committed to creating value for our publisher and advertiser partners in this highly competitive sector."
The commission's decision stems from a formal investigation that it , looking into whether Google violated the bloc鈥檚 competition rules by favoring its own online display advertising technology services at the expense of rival publishers, advertisers and advertising technology services.
European Commission Vice President Margrethe Vestager says Google is dominant on both sides of the ad-selling market. Google abused that position by favoring its own ad exchange, reinforcing its ability to charge a high fee for its services, the commission said.
鈥淕oogle is representing the interests of both buyers and sellers. And at the same time, Google is setting the rules on how demand and supply should meet,鈥� she said at a news conference." This gives rise to inherent and pervasive conflicts of interest.鈥�
YouTube was one focus of the commission's investigation, which looked into whether Google was using the video sharing site鈥檚 dominant position to favor its own ad-buying services by imposing restrictions on rivals.
Google's ad tech business is also under investigation by Britain's antitrust watchdog and faces litigation in the U.S.
Brussels has previously hit Google with more than 8 billion euros (now $8.6 billion) worth of fines in three separate antitrust cases, involving its Android mobile operating system and and services.
The company is appealing all three penalties. EU regulators have the power to impose penalties worth up to 10% of a company鈥檚 annual revenue.
While Google brought in $54.5 billion in ad sales and YouTube earned nearly $6.7 billion in ad sales in the first three months of the year, that marked a back-to-back slump.
