Nielsen

Global leader and de facto currency standard in audience measurement for television, digital, and cross-platform media

Founded in 1923, Nielsen is one of the world's most recognized names in measurement and data analytics, providing audience measurement, advertising effectiveness, and consumer intelligence solutions across media and retail sectors. For over a century, Nielsen has served as the currency of media measurement, enabling broadcasters, streaming platforms, advertisers, and agencies to understand audience behavior across television, radio, digital, and emerging media channels. Its ratings and measurement data are widely used as the industry standard for buying and selling advertising inventory. Nielsen's core offerings span audience measurement (including its flagship TV ratings), digital ad ratings, streaming measurement, and cross-platform analytics. The company's Nielsen ONE platform represents its next-generation unified measurement solution, designed to provide deduplicated, cross-media audience metrics as media consumption continues to fragment across linear TV, connected TV, and digital platforms. Nielsen also provides marketing mix modeling, attribution, and brand lift measurement tools that help advertisers optimize campaign performance and ROI. Nielsen operates as a publicly traded company and holds a dominant position in the media measurement landscape, competing with companies like Comscore, Kantar, and iSpot.tv. After a period of significant corporate activity — including a leveraged buyout and subsequent re-listing — Nielsen remains a critical infrastructure provider for the global advertising and media ecosystem, serving broadcasters, streaming services, advertisers, agencies, and publishers worldwide.
