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). TMAs may cover a much larger area than the stations that serve it, especially since the digital television transition. This is particularly true in markets that have hilly or mountainous terrain that is ill-suited for digital broadcasting. In these cases, the outlying areas of a TMA may only be served by cable and satellite, or perhaps by small translators. (There are some cases, such as that of Olean, New York, where a sizable number of independent stations operate, but none carry any major network affiliation unless they operate as translators. Because of this, Olean is considered part of the Buffalo, New York market despite none of that city's major signals reaching the city from 70 miles away.) Conversely, a geographically small market such as Erie, Pennsylvania may have stations where their signal spills well over into neighboring TMAs (most of Chautauqua County, New York  is closer to Erie than Buffalo, but the county is also located within the Buffalo DMA).
