An Atlanta-based digital advertising company that markets streaming and pop-up videos has sued Google—already under investigation by state attorneys general for possible antitrust activities—over claims its using its sweeping online presence to monopolize the online ad market.

The federal complaint, filed Tuesday in the Northern District of Georgia by Inform Inc., not only seeks damages and an injunction halting Google’s allegedly monopolistic practices but also asks the court to break up the company into separate corporations individually focused on its own advertising business, Android services and Chrome web browser.
