Neilson Media Research
Nielsen ratings refers to Nielsen Media Research, the premier organization that tracks television viewing habits of homes across the country. For over fifty years, Nielsen has been a pioneer and industry leader in audience measurements. The company is known as neutral observer and does not influence results for special interests.
By 2022, this rating system had become archaic in several respects, such as not distinguishing between viewers watching out of addiction (including gambling or spectator football obsession) and viewers using the television as background noise, few of whom are genuine prospects for most advertising.
