Mumbai: Nielsen and Roku have announced a multiyear agreement to integrate Roku’s streaming data with Nielsen’s measurement products, aiming to provide advertisers with a clearer, unified view of a fragmented television landscape. The partnership seeks to tackle the ongoing challenge of accurately tracking viewership across traditional cable, connected TVs, and ad-supported streaming platforms.
Under the deal, Roku’s granular viewer data will feed directly into Nielsen’s “Big Data + Panel” product, a hybrid system that combines traditional viewer diaries with digital signals from millions of set-top boxes and smart TVs.
“This partnership addresses a timely industry need: granular insights that marketers need to grow their brands,” said Ameneh Atai, General Manager of Audience Measurement at Nielsen.
Roku devices currently account for over 21 percent of all television viewing in the U.S., according to Nielsen, giving the measurement firm unprecedented visibility into consumer behavior. In return, Roku gains access to Nielsen’s streaming platform ratings, providing critical insights for The Roku Channel, now the country’s second-largest ad-supported streaming app.
For Nielsen, the partnership is part of its broader effort to maintain its status as the “gold standard” in audience measurement. The “Big Data + Panel” system was accredited by the Media Rating Council earlier this year, but the firm has faced scrutiny over its ability to fully capture the complexity of modern, streaming-first viewing habits.
Recent initiatives include collaborations with Amazon—where Nielsen audience segments are now available via Amazon’s demand-side platform—and Horizon Media, focusing on identity-matching to track viewers consistently across devices.
As the TV industry approaches the “upfront” season, when networks sell the bulk of ad inventory, the alliance underscores that while viewing habits have evolved, the race to accurately count audiences and deliver actionable insights remains fiercely competitive.
