The machinery behind digital advertising rarely draws public scrutiny, but a new settlement involving some of the industry’s most powerful players is forcing a closer look at how decisions about content—and money—have been made behind the scenes.
Federal regulators, alongside a coalition of state attorneys general, announced Wednesday that several major advertising agencies have agreed to stop participating in coordinated efforts that restrict where ads can appear based on political or ideological content. The agreement, if approved by a federal judge, would impose new limits on how firms like Dentsu US Inc., GroupM (WPP Media), and Publicis Inc. interact with one another when determining “brand safety” standards.
At the center of the case is the concept of “brand safety”—a set of guidelines advertisers use to avoid placing ads next to content they consider risky or controversial. According to the Federal Trade Commission, those guidelines evolved into something more structured and, potentially, more restrictive. Regulators allege that, beginning around 2018, these agencies worked through trade associations to establish a shared “Brand Safety Floor,” effectively setting a baseline for what types of content would be excluded from advertising consideration.

The concern, as outlined by the FTC, is not that individual companies made judgment calls about where to spend their money, but that those decisions may have been coordinated. By aligning standards across competing firms, the agencies allegedly reduced competition in the ad-buying market and limited the ability of advertisers to make independent choices tailored to their own preferences.
Texas Attorney General Ken Paxton framed the issue in more direct terms, arguing that the coordinated practices amounted to an effort to suppress certain viewpoints by cutting off revenue streams to publishers. In his view, the impact extended beyond market dynamics into questions of free expression, particularly for conservative-leaning outlets.
Under the terms of the settlement, the agencies have agreed not to enter into agreements that would restrict business with publishers based on political viewpoints or ideological content. They also committed to avoiding coordinated limits tied to diversity, equity, and inclusion criteria. Oversight will come in the form of a court-appointed monitor tasked with ensuring compliance.
FTC Commissioner Andrew Ferguson emphasized the antitrust dimension, stating that the alleged coordination disrupted normal competitive pressures and constrained both advertisers and publishers. He argued that removing those shared restrictions would restore a more open marketplace, where decisions about ad placement are made independently rather than collectively enforced.
