How Google defended itself in the ad tech antitrust trial

Over the past week, Google has called more than a dozen witnesses to defend itself against claims by the Justice Department and a group of state attorneys general that it has a monopoly in advertising software that places ads on web pages, part of a second major federal antitrust trial against the tech giant.

Google’s lawyers wrapped up their arguments in the case on Friday, and the government will now offer a rebuttal. Judge Leonie Brinkema of the US District Court for the Eastern District of Virginia, who is presiding over the nonjury trial, is expected to deliver a ruling by the end of the year, after both sides summarize their cases in writing and deliver closing arguments.
