Google faces new antitrust trial after ruling declaring search engine a monopoly

One month after a judge declared Google’s search engine an illegal monopoly, the tech giant faces another antitrust lawsuit that threatens to break up the company. The Justice Department and a coalition of states contend Google built and maintains a monopoly over the technology that matches advertisers to online publishers. The government contends Google's dominance over the software on both the buy side and the sell side of the transaction enables it to keep up to 36 cents on the dollar when it brokers sales between publishers and advertisers. Google says the government’s case is based on an outdated perception of the internet, when desktop computers dominated the landscape. The trial begins Monday in federal court in Alexandria, Virginia.
