Trial Opens in Antitrust Case Against Google Over Online Ads

The Justice Department told a federal judge that Google had built a monopoly in lucrative technology that delivers online ads, kicking off a second federal antitrust trial against the tech giant amid mounting scrutiny of the industry. Google used its acquisition of the advertising software company DoubleClick in 2008 to dominate technology that auctions off ads on web pages as users visit, Julia Tarver Wood, the government’s lead trial lawyer, said in opening statements.
