Nielsen, Mediaocean Announce New Integration to Power The Next Phase of Data-Driven Linear, Advanced Audience Measurement

MRI-Simmons and S&P Global Mobility are expanding advanced audience capabilities into Nielsen ONE.

The collaboration will help drive greater interoperability by allowing marketers to maintain a single, consistent audience definition throughout the campaign lifecycle.

June 4, 2026 - New York - Nielsen, a global leader in audience measurement, data and media intelligence, today announced a new collaboration with Mediaocean to power the next phase of advanced audience measurement in today's rapidly evolving media landscape.

Nielsen will provide reporting on advanced audience segments for data-driven linear (DDL) national TV campaigns to expand the integration of its Big Data + Panel audience measurement solution directly within Mediaocean's Prisma platform, the trusted system of record for global media investment.

The collaboration will help drive greater industry interoperability by allowing marketers to maintain a single, consistent audience definition throughout the advertising journey. Clients can define advanced audience segments (first- and third-party and Nielsen-owned) within Nielsen Audience Builder and then see the corresponding measurement metrics directly within Mediaocean.

By doing so, the two companies are helping marketers move beyond traditional age and gender based demographics by enabling more advanced audience definitions to be applied consistently across ad planning and measurement workflows.

The collaboration also brings greater continuity and visibility into data-driven linear campaigns, giving advertisers a better way to understand and evaluate multi-screen ad performance.

Said Nielsen Chief Product Officer Akhil Parekh: "Advertising's next frontier will be built on true interoperability - not just data sharing, but a consistent audience definition that travels from planning all the way through to measurement. Together with Mediaocean, we're giving marketers exactly that: the ability to define audiences once and then to carry that precision across the entire campaign lifecycle."

"The big theme here is consistency," said Prisma Chief Product Officer Drew Kane. "As the advertising ecosystem becomes increasingly fragmented, maintaining a consistent audience definition across planning, activation, and measurement has become a challenge. By teaming up with Nielsen, we are helping to create a more connected workflow that brings greater visibility and alignment across the marketing journey."

Concurrently, S&P Global Mobility is integrating insights from its Polk Automotive Solutions Portfolio, a leader in automotive advanced audiences insights, so that marketers can better reach customers in this sector. (Polk intelligence encompasses nearly 35 years of vehicle owner history, more than one billion vehicle transactions annually, and more than 650 million vehicles tracked daily.)

Marketers and agencies can now leverage Polk Audiences across Nielsen's planning and measurement products, including Nielsen Audience Builder, Nielsen Media Impact, Nielsen ONE Planning and Nielsen ONE Ads. These audiences will also be available against Nielsen's Big Data+Panel data and integrated into Nielsen's digital planning/measurement solutions.

MRI-Simmons, a leading provider of survey-based insights about American consumers, is likewise expanding its relationship with Nielsen to deliver new, research-driven audience insights within Nielsen ONE planning and measurement tools.

The overall upside for clients is improved campaign performance, via even better data-driven planning, measurement, and optimization capabilities.

This integration and its resulting capabilities will officially launch in September, just in time for the fall 2026 TV season.
