US prepares to challenge Google’s online ad dominance

Washington: For years, Google has faced complaints about how it dominates the online advertising market.

Many of the concerns stem from the internet giant’s suite of software known as Google Ad Manager, which websites around the world use to sell ads on their sites. The technology conducts split-second auctions to place ads each time a user loads a page.

The dominance of that technology has landed Google in federal court. On Monday, Judge Leonie Brinkema of the US District Court for the Eastern District of Virginia will preside over the start of a trial in which the Department of Justice accuses the company of abusing control of its ad technology and violating antitrust law.
