In an original decision in 2017, Google was fined for giving its own shopping recommendations an illegal advantage over rivals in search results.

Google has suffered another significant legal blow in Europe, as the European Court of Justice (ECJ) upheld a €2.42 billion ($2.65 billion) fine over antitrust violations involving its shopping comparison service.

The $2.7 billion fine may affect the conduct of other tech giants. Some experts urge the U.S. to follow Europe's regulatory lead.
