Nielsen: Co-viewing pilot delivers 4% increase for live TV events

May 5, 2026

Nielsen, the audience measurement specialist, data and media intelligence, has announced the results of its co-viewing pilot for February’s top live televised events. 

The new data shows an average +4.19 per cent lift in total viewers for the following marquee live events: Super Bowl LX, Olympics Opening Ceremony, NBA All Star Game, Daytona 500, Olympics Closing Ceremony, Olympics Men’s Hockey Gold Medal Game and State of the Union Address.

The co-viewing results from the pilot programme will not be included in final and official Big Data + Panel ratings for Nielsen clients, thus will not be considered ‘currency’ that advertisers transact on. Nielsen plans to have the co-viewing methodology enhancement fully implemented into its suite of media intelligence products with a goal of incorporating it into currency measurement for the 2026/2027 TV season.

“Our Co-Viewing pilot exemplifies our unwavering commitment to providing the most accurate measurement for our clients during these dynamic times of change,” commented Karthik Rao, CEO, Nielsen. “In the past year alone we’ve made continued enhancements to our ratings to better reflect the power of live TV in reaching massive audiences.”

Nielsen’s co-viewing enhancement layers in panelists using wearable devices inside of the home. Those wearable devices were not previously applied to the co-viewing modeling, as Nielsen has been introducing more high-tech wearables into its panel.
