Television station

A television station is a business or other organisation that transmits (broadcasts) programs over terrestrial television
A television transmissions can be by analog television signals or, more recently, by digital television.
The television broadcasting standards are set by the government, and these vary around the world. 
Television stations broadcasting over an anolog system were typically limited to one television channel, but digital television enables them to broadcast subchannels
The term is normally applied to terrestrial television stations, and not to cable or satellite television broadcasting.
Television stations usually require a license from a government agency which set many requirements and limitations on the station. The licence will, for example, define the geographic area that the station is limited to and allocate the broadcast frequency of the radio spectrum for that station's transmissions, and places limits on what types of programs can be broadcast and requires a station to broadcast a minimum amount of certain programs, besides many other conditions.
Most television stations are owned independently, but many are either affiliated with a television network or are owned by a television network
To avoid concentration of media ownership of television stations, government regulations in most countries around the world generally limit the ownership of television stations by television networks or other media operators, but these regulations vary considerably. 
Some countries have set up nationwide television networks, in which individual television stations act mere as repeaters of nationwide programs. In those countries, the local television station has no station identification and, from a consumer's point of view, there is no practical distinction between a network and a station, with only small regional changes in programming, such as local news
