High Quality Content by WIKIPEDIA articles! A television network is a telecommunications network for distribution of television content, whereby a central operation provides programming to many television stations or pay TV providers. Until the mid-1980s, television programming in most countries of the world was dominated by a small number of broadcast networks. Many early television networks (e.g. the BBC, NBC or CBS) evolved from earlier radio networks. In countries where most networks broadcast identical, centrally originated content to all their stations and where most individual TV transmitters therefore operate only as large "repeater stations", the terms "television network", "television channel" (a numeric identifier or radio frequency), and "television station" have become mostly interchangeable in everyday language, with professionals in TV-related occupations continuing to make a difference between them.
