Nielsen

Nielsen, operated by Nielsen Holdings, is a global audience-measurement, data, and analytics company. The original A. C. Nielsen Company was founded in 1923 in the United States by Arthur C. Nielsen Sr. and pioneered the use of statistical measurement to estimate media consumption. The current Nielsen entity emerged after a series of corporate transactions including its initial public offering in 2011, the 2021 separation of its consumer-packaged-goods Global Connect business as NielsenIQ, and its take-private acquisition by a consortium led by Elliott Investment Management and Brookfield Business Partners in 2022. Nielsen is co-headquartered in New York City and Tampa-area Florida.

Nielsen's offerings centre on Nielsen ONE, a cross-platform measurement product designed to unify audience measurement across linear television, connected television, digital, and streaming, alongside content metadata and analytics under the Gracenote brand, marketing-effectiveness measurement, and audience segments and activation. The company serves broadcasters, streaming platforms, publishers, ad agencies, advertisers, and content owners.
