Media market
The examples and perspective in this article deal primarily with North America and do not represent a worldwide view of the subject. (October 2011) |
A media market, broadcast market, media region, designated market area (DMA), television market area, or simply market is a region where the
Markets are identified by the largest city, which is usually located in the center of the market region. However, geography and the fact that some metropolitan areas have large cities separated by some distance can make markets have unusual shapes and result in two, three, or more names being used to identify a single region (such as Wichita–Hutchinson, Kansas; Chico–Redding, California; Albany–Schenectady–Troy, New York; and Harrisburg–Lebanon–Lancaster–York, Pennsylvania).

Television
A Television Market Area (TMA) is a group of counties in the United States covered by a specific group of
A similar term used by Nielsen Media Research is the Designated Market Area (DMA), and they control the trademark on it. DMAs are used by Nielsen Media Research to identify TV stations that best reach an area and attract the most viewers. There are 210 Nielsen DMAs in the United States, 70 of which are metered (in other words, viewership in these markets are estimated automatically instead of through the archaic diary system still in use in the smaller markets).[5][6]
TMAs may cover a much larger area than the stations that serve it, especially since the
Arbitron (now Nielsen Audio) also maintained similar areas for television ratings, each called an "area of dominant influence" (ADI), which were first created in 1966.[7] For the 1993–1994 television season, there were 209 ADIs in the continental United States.[8] Arbitron stopped offering a television ratings service in late 1993.[9]
Radio
Nielsen Audio (previously Arbitron) maintains smaller areas for radio stations; each is called an Arbitron Radio Metro. Whereas a typical TMA may cover ten counties, an Arbitron market generally covers two to four, and a TMA may contain two to four separate Radio Metros. There are 302 Radio Metros in the United States, but not all areas of the country are covered.
In 2009, Nielsen began offering radio ratings in competition with Arbitron, starting in those markets ranked 101st and smaller.[10]
