(DMA)–The formal term for what is more commonly known as a TV or broadcast market. DMA's are selected by totaling the viewer hours of TV stations whose signals reach a particular county with total hours, then converted to a percentage share of all viewing hours. DMA's are named for the market of origin of the station(s) with the largest share of viewer hours, and all counties whose largest viewer share is given to stations in that same market of origin are grouped together under that DMA. NOTE: Because of the reach of broadcast signals, DMA's don't always conform to whole-county geography like metro markets or newspaper markets. In certain cases, Nielsen splits counties, treating each portion as if it were a separate county. Each county, or portion thereof, is allocated to a single DMA, eliminating any geographic overlap. DMA's cover the whole U.S., except for parts of Alaska.
A Nielsen geography defined by television viewing, not radio listening, patterns. It may or may not include all counties in the Metro or TSA.

Nielsen Media Research established standards to determine the market area for a broadcast station.
Designated market audience for a television or radio station. Area includes all locations within the strength of the signal. The larger the city the higher DMA rank.

DMAâ€™s are used by Nielsen Media Research to identify TV stations whose broadcast signals reach a specific area and attract the most viewers. A DMA consists of all counties whose largest viewing share is given to stations of that same market area. The continental U.S., Hawaii, and parts of Alaska currently consist of 210 non-overlapping DMAâ€™s.( Back to the top)
Designations by A.C. Nielsen similar in concept to ARB's Area of Dominant influence (ADI). A DMA is generally a group of counties in which stations located in the Metro Area achieve the largest audience share. Like ADIs, DMAs are exclusive in that they don't overlap.
A unique geographic area defined by Nielsen Media Research so that the entire US is assigned to one of some 210 DMAs.
A television market as delineated by the A.C. Nielsen Company.
Geographical area comprised of a market and adjacent counties or census divisions, as defined by Nielsen Media Research.
