Nielsen is an American market research and audience measurement company that supplies standardized data used across television, digital media, streaming, and advertising markets. Founded in 1923, it is widely known for establishing industry benchmarks that guide media planning and ad pricing.

Measurement Services

The company operates large-scale consumer panels and data integrations to track viewership, listening, and engagement across linear TV, connected devices, and online platforms. Its analytics support broadcasters, publishers, streaming services, and advertisers in understanding reach, frequency, and performance.

Role in the Media Ecosystem

Nielsen functions as an independent measurement authority within the media value chain, providing trusted third-party insights rather than producing or distributing content. Its datasets influence programming decisions, advertising spend allocation, and long-term media strategy across global markets.
