Audience Measurement

Today’s program content is viewed on more than just television sets. Consumers are watching via the Internet and on mobile devices, in-home and out-of-home, live and time-shifted, free and paid, rebroadcast and original programs. Nielsen provides advanced measurement solutions, rich demographic data and deep behavioural insights that help clients understand how consumers engage with media within and across all the platforms they use—TV , online, mobile and emerging.


We measure national TV viewing using Nielsen’s People meter technology to electronically capture all viewing from our nationally projectable sample of panelists.

Nielsen representative panels of Internet users provide browsing and streaming metrics for online users. Using census-based measurement, we provide in-depth tracking and analysis of site performance as well as information about audience consumption of, and engagement with, streaming media.

And for mobile media, we are pursuing on-device meter panels to record every interaction users have with measurable mobile devices, which complement our robust survey data.

Finally, through single-source panels along with modelled databases, we measure how consumers engage with multiple media platforms.


Nielsen TV/Internet Data Fusion service integrates the Nielsen National People Meter Panel with the Nielsen Online panel through the use of common data elements to provide a consumer-centric view of media usage.

Nielsen Cross-Platform Homes provides single-source cross-media measurement, which supplies innovative data from the only dataset to measure TV and Internet in the same household. Nielsen currently uses this data to measure the online contribution to television ratings.
