Other Meanings
Commonly, the term "television channel" is used to refer to either a terrestrial television station or its cable/satellite counterpart (both outlined below). Sometimes, especially outside the U.S. and in the context of cable/satellite television, it is used instead of the term television network, which otherwise (in its technical use above) describes a group of geographically-distributed television stations that share affiliation/ownership and some or all of their programming with one another.
This terminology may be muddled somewhat in other jurisdictions, for instance Europe, where terrestrial channels are commonly mapped from physical channels to common numerical positions (i.e. BBC One does not broadcast on any particular "channel 1" but is nonetheless mapped to the "1" input on most British television sets). On digital platforms, such (location) channels are usually arbitrary and changeable, due to virtual channels.

Famous quotes containing the word meanings:
“An amoeba is a formless thing which takes many shapes. It moves by thrusting out an arm, and flowing into the arm. It multiplies by pulling itself in two, without permanently diminishing the original. So with words. A meaning may develop on the periphery of the body of meanings associated with a word, and shortly this tentacle-meaning has grown to such proportions that it dwarfs all other meanings.”
—Charlton Laird (b. 1901)
“The first green night of their dreaming, asleep beneath the Tree,/God said, “Let meanings move,” and there was poetry.”
—Muriel Rukeyser (1913–1980)
