Nielsen ratings measure the popularity of American television programs. Developed by Nielsen Media Research, the ratings are not qualitative evaluations of how much a program is "liked," but, instead, how many many people watched.

In essence, Nielsen ratings help determine the audience size and composition of television programming.

To learn more about how Nielsen collects the data to make the numbers come to life, see Ratings & Data, Sampling & Recruiting, and Meters & Diaries.
