Nielsen Media Research
Nielsen Media Research (
NMR) is a
U.S. firm, headquartered in
New York City, and operating primarily from
Oldsmar,
Florida, which
measures media audiences, including
television,
radio and
newspapers. NMR is best-known for the
Nielsen Ratings, a measurement of television viewership.
Nielsen Media Research began as a division of
ACNielsen, a
marketing research firm. In
1996, Nielsen Media Research was split off into an independent company, and in
1999, was purchased by the
Dutch conglomerate VNU. In
2001, VNU also
purchased ACNielsen, thereby bringing both companies under the same corporate umbrella.
Nielsen Media Research is a sister company to
Nielsen//NetRatings, which measures
Internet and
digital media audiences, and
Nielsen BuzzMetrics, which measures Consumer-Generated Media.
