leading provider of television information services in the United States and Canada, serving national and local customers including television networks and affiliates, independent stations, syndicators, cable networks, cable systems, and advertisers and their agencies. Nielsen Media Research provides to those they serve reports of consumer television viewing habits based on two separate sets of data. The first consists of data collected by meters attached to household television sets that report when the television is on and to what channel it is tuned, and, with the aid of People Meters (which measure who is watching television through the assignment of a button to each member of the household, including visitors, which when pushed indicates exactly which member of the household is watching the television), who is watching the television. The second set of data consists of listings of what programs are on those channels tuned.
Headquartered in New York City with offices in major markets throughout the United States and Canada, Nielsen Media Research is an independent, publicly traded company.
