Supreme Court reviews video privacy law for targeted ads

That matters economically because targeted advertising remains one of the most lucrative models in digital media, and a ruling against Paramount could force companies to seek consent more often or scale back data-driven ad products. The dispute also tests whether consumer privacy law written for a physical-video era can be applied to online content consumption, email newsletters and cross-platform tracking.

At argument, lawyers for Paramount said the plaintiff was not a “consumer” under the law because he did not buy video content, while the plaintiff’s counsel argued Paramount “built its model” around sharing personal identifiers without consent. Several conservative justices sounded skeptical of stretching the statute into internet ad-tech territory, with Justice Brett Kavanaugh calling that a “reorientation” of the law.

Investors are watching because a broad reading could add legal risk for Paramount, which already faces pressure to defend margins in a tougher media ad market, and could also create a wider compliance overhang for peers including Disney, Netflix and other streaming and publishing platforms that rely on audience data. Paramount shares are not part of the case, but the legal question goes to the economics of digital advertising across media.

The court is expected to rule by the end of its term in June, and the decision could set the boundary for privacy litigation in the streaming and ad-tech sectors for years.
