“Today’s lawsuit seeks to hold Google to account for its longstanding monopolies in digital advertising technologies that content creators use to sell ads and advertisers use to buy ads on the open internet,” said Assistant Attorney General Jonathan Kanter of the Justice Department’s Antitrust Division. “Our complaint sets forth detailed allegations explaining how Google engaged in 15 years of sustained conduct that had — and continues to have — the effect of driving out rivals, diminishing competition, inflating advertising costs, reducing revenues for news publishers and content creators, snuffing out innovation, and harming the exchange of information and ideas in the public sphere.”
Google now controls the digital tool that nearly every major website publisher uses to sell ads on their websites (publisher ad server); it controls the dominant advertiser tool that helps millions of large and small advertisers buy ad inventory (advertiser ad network); and it controls the largest advertising exchange (ad exchange), a technology that runs real-time auctions to match buyers and sellers of online advertising.
Graphic describing Google's role in Ad-Tech industry Google’s anticompetitive conduct has included:
Acquiring Competitors: Engaging in a pattern of acquisitions to obtain control over key digital advertising tools used by website publishers to sell advertising space; Forcing Adoption of Google’s Tools: Locking in website publishers to its newly-acquired tools by restricting its unique, must-have advertiser demand to its ad exchange, and in turn, conditioning effective real-time access to its ad exchange on the use of its publisher ad server; Distorting Auction Competition: Limiting real-time bidding on publisher inventory to its ad exchange, and impeding rival ad exchanges’ ability to compete on the same terms as Google’s ad exchange; and Auction Manipulation: Manipulating auction mechanics across several of its products to insulate Google from competition, deprive rivals of scale, and halt the rise of rival technologies. As a result of its illegal monopoly, and by its own estimates, Google pockets on average more than 30% of the advertising dollars that flow through its digital advertising technology products; for some transactions and for certain publishers and advertisers, it takes far more. Google’s anticompetitive conduct has suppressed alternative technologies, hindering their adoption by publishers, advertisers, and rivals.
