Television Stations and Channels
A television station broadcasts video and audio to television
receivers in a particular area. Traditionally, TV stations made
their broadcasts by sending specially-encoded radio signals over the
air. Individual television stations are usually granted licenses to
use a particular section of the radio spectrum (a channel) through
which they send their signals.
The term television channel has
become synonymous with "TV station" and even television network,
leading to confusion. Television stations usually just have one transmitter, but are also generally
associated with a nationwide television network, through which they
get significant amounts of programming. Because some regions have
had difficulty picking up over-the-air signals (particularly in
mountainous areas), satellite and cable television has been
introduced.
Television stations specifically built to run on cable
or satellite blur the line between TV station and TV network. That
fact led some early cable networks to call themselves superstations.
Broadcast stations in an area can sign up to be carried on cable,
but content providers like TLC Network can too. They aren't licensed
to run broadcast equipment like a station and they don't regularly
provide content to licensed broadcasters either.
Furthermore, a
distributor like TNT may begin producing its own programming, and
shows presented exclusively on cable by one distributor may be
syndicated to broadcast stations.
A person viewing by cable or satellite may not know what kind of
organization is responsible for the program. So what seems to be a
station or a network may be neither.
