MDL 3010Antitrust

Google Digital Advertising Antitrust Litigation

The plaintiffs' economic causation theory posits that Google's monopolistic control over digital advertising markets—through practices such as suppressing header bidding, acquiring competitors like DoubleClick, and engaging in tying arrangements—has artificially inflated advertising costs for buyers and suppressed revenues for publishers. This conduct has resulted in economic harms including increased operational costs for advertisers, diminished revenue streams for publishers, and market exclusion of smaller competitors, thereby entrenching Google's dominant market position.
