The Federal Trade Commission has announced settlements with three of the world’s largest advertising agencies—WPP, Publicis, and Dentsu—over allegations that they coordinated brand-safety standards in a way that excluded or disadvantaged media outlets based on political content. The case, filed in federal court in Fort Worth, Texas, is a significant signal that the FTC is willing to treat certain forms of industrywide content-related coordination as a competition problem, not merely a speech or platform-governance dispute.

According to the FTC, the agencies’ alleged conduct effectively created a boycott by steering advertising dollars away from publishers or platforms deemed politically objectionable under shared standards.
