Google and the US Department of Justice delivered closing arguments in an antitrust case targeting Google's advertising technology.
The Justice Department seeks to force Google to sell parts of its ad tech business, claiming it constitutes a monopoly in open-web display advertising.
Google argues that open-web display advertising is an artificial category and that it controls only around 10% of the market.
The Justice Department refutes Google's argument and cites internal comments suggesting Google's aim to dominate display advertising.
