The Nielsen Corporation, self-referentially known as The Nielsen Company, and formerly known as ACNielsen or AC Nielsen, is a global marketing research firm, with worldwide headquarters in New York City, United States. Regional headquarters for North America are located in Chicago.
As of May 2010, it is part of Nielsen Holdings.
This company was founded in 1923 in Chicago by Arthur C. Nielsen Sr. in order to give marketers reliable and objective information on the impact of marketing and sales programs. ACNielsen began expanding internationally in 1939, and now operates in more than 100 countries.
One of Nielsen's best known creations is the Nielsen ratings, an Audience measurement system that measures television, radio and newspaper audiences in their respective media markets. In 1950, they acquired the C. E. Hooper company and began attaching recording devices to a statistical sample of about 1,200 consumer television sets in the U.S. These devices used photographic film in mail-in cartridges to record the channels viewed by the consumer and thus determine audience size. Later they developed electronic methods of data collection and transmission. In 1996, Nielsen split off this part of its operations into a separate company called Nielsen Media Research (NMR), which operated as an independent company until it was acquired by Dutch conglomerate VNU in 1999. The company was headquartered in Stamford, Connecticut before the acquisition by VNU.
Another market research tool is the Homescan program where sample members track and report all grocery and retail purchases, allowing purchasing patterns to be related to household demographics. Homescan covers several countries including Australia, Canada, the United Kingdom, and the United States. In 2004, ACNielsen chose the CipherLab CPT-8001 as its data collection terminal for the Homescan program throughout Asia.
In Germany, ACNielsen gained reputation for their introduction of the Nielsen areas (or Nielsengebiete in German), each of which includes one or more German federal states sharing a similar economic structure, culture, and consumer behaviour. Marketing strategies in Germany depend considerably on the Nielsengebiete, to the extent that some trademarks or marketing campaigns have only been introduced in some of the Nielsengebiete. In many newspapers and magazines disseminated nationwide, advertisements may be placed for just one or some Nielsengebiete; the circulation figures of print media are often stated according to Nielsengebiete as well.
Mergers and acquisitionsEdit
In 2001, ACNielsen itself was acquired by VNU, as part of VNU's Marketing Information group, and thus is now under the same corporate umbrella as the company it spawned, NMR. Nielsen Media Research is based in New York City, while ACNielsen headquarters remain in Schaumburg, Illinois.
In 2005, ACNielsen initiated their MVP (Media Voice Panel) program. Panel members carry an electronic monitor that detects the digital station and program identification codes hidden within the TV and radio broadcasts they are exposed to. At night, members place the monitor in a cradle that sends the collected data through the home's electrical wiring to a relay device that transmits it by phone, making it one of the first practical uses of electrical wiring as a home network. With an approximately one week notice to members, the MVP program ended on March 17, 2008.
In 2007, the owner VNU changed its name to "The Nielsen Company".
