single cross-media currency

Audience is EverythingTM — Audiences no longer see a difference between traditional TV, streaming and digital. So your measurement shouldn’t either. The media industry needs cross-media measurement that’s complete and provides comparable metrics for ads and content across platforms, services and devices. And this measurement needs to reflect consumption by actual people.

Nielsen is embracing a “ONE” mindset to modernize its panels, platforms and products to create a single, cross-media currency, so you’re able to buy and sell across linear and digital platforms seamlessly.

Measurement transformed

As audiences move seamlessly between linear, streaming and digital, advertisers are demanding a single, deduplicated view of their audience across all platforms and mediums, while publishers want to provide more ad options for buyers and improve the overall viewer experience.

With a single, deduplicated number from Nielsen ONE, you will have visibility into audiences by platform, as well as the unique demographic profile of each publisher. And with these insights, you’ll be able to effectively adapt to future platforms and devices.

ONE panel

A single-source, geographically representative panel will measure viewing across devices, while underpinning Nielsen’s ID resolution system to validate audiences and deduplicate exposures across ads and content.

Multiple devices connected by a cloud-based platform


A unified cloud-based platform will allow easy integration and normalization of big data, as well as direct integrations with digital platforms, using a variety of best-in-class models that leverage machine learning.
