Comcast SportsNet

Comcast SportsNet (CSN), also known under the corporate names NBC Sports Regional Networks or Comcast Sports Group, is the collective name for a group of regional sports networks in the United States that are primarily owned and operated by Comcast, and operated through the NBC Sports Group unit of NBCUniversal.

Each of the networks carry regional broadcasts of sporting events from various professional, collegiate and high school sports teams (with broadcasts typically exclusive to each individual network, although some are shown on more than one CSN network within a particular team's designated market area), along with regional and national sports discussion, documentary and analysis programs. In addition to the seven Comcast SportsNet-branded networks, Comcast is also has a partial ownership interest in SportsNet New York (co-owned with Time Warner Cable and the New York Mets).

Depending on their individual team rights, some Comcast SportsNet outlets maintain overflow feeds available via digital cable, telco and satellite providers in their home markets, which may provide alternate programming when not used to carry game broadcasts that the main feed cannot carry due to scheduling conflicts. Comcast SportsNet's business and master control operations are based in New York City, New York.
