A terrestrial network (or broadcast network in the United States) is a group of radio stations, television stations, or other electronic media outlets, that form an agreement to air, or broadcast, content from a centralized source.^[1] For example, ABCTooltip American Broadcasting Company (U.S.), CBC/Radio-CanadaTooltip Canadian Broadcasting Corporation (Canada), the BBCTooltip British Broadcasting Corporation (UK), the ABCTooltip Australian Broadcasting Corporation (Australia), ARDTooltip ARD (broadcaster) (Germany), KBSTooltip Korean Broadcasting System (South Korea), and NHK (Japan) are TV networks that provide programming for local terrestrial television station affiliates to air using signals that can be picked up by the home television sets of local viewers.^[1] Networks generally, but not always, operate on a national scale; that is, they cover an entire country.

Streaming media, Internet radio, and webcasting are sometimes considered forms of broadcasting despite the lack of terrestrial stations; its practitioners may also be called "broadcasters" or even "broadcast networks".
