The European Commission has asked rival companies to permit disclosure to Google of confidential information they submitted that support allegations that it abuses its dominance in advertising.
As in previous antitrust cases, the commission typically circles back to companies to make specific information nonconfidential because it will have to show Google the evidence it has based its charges on.
Margrethe Vestager, the EU s antitrust chief, has already slapped Google with formal antitrust charges for allegedly skewing its search results to favor its own shopping service, and more recently in April, over Google s conduct with its Android mobile operating system.
The EU is also looking into whether Google restricts advertisers that use Google s auction-based advertising service, where they bid for the placement of ads on search result pages, from moving to other search advertising platforms.
The U.S. Federal Trade Commission closed a similar investigation in 2013 after Google committed to removing restrictions imposed on advertisers trying to coordinate their online advertising campaigns across several platforms.
News Corp, NWSA -4.81 % publisher of The Wall Street Journal, has filed formal complaints with the commission regarding Google s business practices, including an allegation the U.S. tech giant reinforces its dominance in general search by scraping or copying content from publishers to display the results of news articles.
