Should federal antitrust laws more strictly regulate how companies bundle products for their clients?

The Supreme Court has scheduled a November 13 conference to consider a petition from Nielsen regarding an antitrust injunction. The case centers on whether the company's ratings pricing methods constitute unlawful tying under the Sherman Act.

Why it matters

Nielsen argues the lower court's ruling conflicts with existing precedents in the Sixth and Ninth Circuits. The outcome may clarify standards for pricing liability and constructive tying in the advertising industry.

A district court initially set daily sanctions at $50,000 for failure to submit a compliant pricing offer. This order was subsequently stayed by the Second Circuit on September 10 pending further judicial review.

The players

Nielsen

Nielsen is a global measurement and data analytics company that provides audience insights for the media and advertising industries.

Cumulus

Cumulus is a major American radio broadcasting company that owns and operates hundreds of stations across the United States.

US Supreme Court

The US Supreme Court is the highest judicial body in the United States and holds the authority to interpret federal law and constitutional issues.

Second Circuit

The Second Circuit is a federal appellate court that hears appeals from district courts located in New York, Connecticut, and Vermont.

The details

The Second Circuit previously affirmed a preliminary injunction against Nielsen after finding that the standalone price of its Nationwide report created an unlawful tie. Cumulus, the opposing party in the suit, originally secured the injunction in late December.

December 30: District court granted a preliminary injunction to Cumulus.
July 13: The Second Circuit affirmed the preliminary injunction against Nielsen.
August 18: The Second Circuit denied Nielsen's petition for a rehearing.
September 9: The district court ordered Nielsen to submit a compliant pricing offer.
November 13: Supreme Court conference to consider the petition.

Market Landscape

The legal battle highlights ongoing tensions regarding how antitrust laws like the Sherman Act apply to bundle-based pricing models in data-heavy industries. This case positions the court to potentially set a new threshold for what constitutes unlawful tying in the media measurement sector.

The court's decision will determine if Nielsen is forced to alter its current pricing structures for Nationwide reports. For advertisers and media companies, this could lead to changes in how audience measurement data is packaged and priced in future contracts.

The takeaway

Antitrust litigation involving major data providers can trigger broad shifts in how essential industry services are priced and sold. Businesses relying on third-party metrics should monitor these legal developments as they may impact long-term procurement costs.
