Justice Dept. Sues Google, Says It Monopolizes Digital Advertising Technologies

The Justice Department, along with the Attorneys General of California, Colorado, Connecticut, New Jersey, New York, Rhode Island, Tennessee, and Virginia, filed a civil antitrust suit against Google for monopolizing multiple digital advertising technology products in violation of Sections 1 and 2 of the Sherman Act.

The complaint alleges that Google monopolizes key digital advertising technologies, collectively referred to as the “ad tech stack,” that website publishers depend on to sell ads and that advertisers rely on to buy ads and reach potential customers. Website publishers use ad tech tools to generate advertising revenue that supports the creation and maintenance of a vibrant open web, providing the public with unprecedented access to ideas, artistic expression, information, goods, and services. Through this monopolization lawsuit, the Justice Department and state Attorneys General seek to restore competition in these important markets and obtain equitable and monetary relief on behalf of the American public.
