Nielsen to exit Puerto Rico audience measurement by December 2026
Nielsen will discontinue its radio and television audience measurement services in Puerto Rico by December 2026. The decision creates a significant challenge for local broadcasters who must now look to alternative providers for independently validated audience metrics.
Key Takeaways
- The 5 companies currently subscribing to Nielsen Audio in Puerto Rico represent less than 20% of the island's total radio listening.
- Hemisphere Media Group, a major player, owns the two highest-rated subscribing stations and three of the top five.
- Spanish Broadcasting System (SBS), a dominant market leader, currently does not subscribe to Nielsen Audio in the region.
- TV broadcasters have existing fallback options such as Comscore, iSpot.tv, and VideoAmp, but radio has no current alternative.
- Nielsen will provide a handover period through December 2026 to facilitate a transition to new local measurement stakeholders.
Why It Matters
The removal of Nielsen's metrics threatens to destabilize Puerto Rico’s broadcast economy by eliminating the primary currency used for agency transactions. Without independently validated reach and frequency data, local stations risk losing ad budgets to global digital platforms that offer granular attribution. While the TV sector is insulated by established rivals like Comscore and VideoAmp, the radio industry faces a critical lack of third-party alternatives. This move underscores a broader trend where Nielsen is consolidating resources, potentially leaving smaller or fragmented markets without standardized measurement. Watch for a collective push by local broadcasters to fund a new joint measurement service before the 2027 media-buying cycle begins.
Additional Context
The withdrawal from Puerto Rico aligns with Nielsen's broader focus on overhauling its national 'Big Data + Panel' service to maintain Media Rating Council (MRC) accreditation. Per MediaPost (March 2026), Nielsen has recently cut other localized services, including its SIGMA Radio ad monitoring across 137 U.S. markets, as it prioritizes its cross-platform Nielsen One suite. These cuts follow intense scrutiny of Nielsen's demographic accuracy regarding Hispanic and Spanish-dominant households. In May 2026, the MRC reaffirmed Nielsen’s national accreditation only after the company integrated third-party universe estimates from the Advertising Research Foundation (ARF) to better represent minority audiences. While Nielsen narrows its footprint, rivals are aggressively expanding their local market capabilities. Per Comscore (April 2026), the company secured multi-year agreements with over 15 major station groups including Sinclair and E.W. Scripps, positioning itself as a direct alternative for local currency. Similarly, the U.S. Joint Industry Committee (JIC) reaffirmed the 'currency-grade readiness' of Comscore, iSpot, and VideoAmp in July 2025, providing a blueprint for the multi-currency environment Puerto Rico may now be forced to adopt. For Puerto Rican media, the challenge is localized; unlike the continental U.S., digital transition metrics remain tied to traditional broadcast consumption, which still commands significant reach per bMedia Group reports (May 2026).
