Answer: What is Cable Television mean?

Cable television is a system of delivering television programming to consumers via radio frequency (RF) signals transmitted through coaxial cables, or in more recent systems, light pulses through fibre-optic cables. This contrasts with broadcast television (also known as terrestrial television), in which the television signal is transmitted over-the-air by radio waves and received by a television antenna attached to the television; or satellite television, in which the television signal is transmitted over-the-air by radio waves from a communications satellite orbiting the Earth, and received by a satellite dish antenna on the roof. FM radio programming, high-speed Internet, telephone services, and similar non-television services may also be provided through these cables. Analog television was standard in the 20th century, but since the 2000s, cable systems have been upgraded to digital cable operation.

A "cable channel" (sometimes known as a "cable network") is a television network available via cable television. When available through satellite television, including direct broadcast satellite providers such as DirecTV, Dish Network and Sky, as well as via IPTV providers such as Verizon FIOS and AT&T U-verse, this is referred to as a "satellite channel". Alternative terms include "non-broadcast channel" or "programming service", the latter being mainly used in legal contexts. Examples of cable/satellite channels/cable networks available in many countries are TVNZ 1, ABC, RTM TV1, NHK General TV, KBS1, CCTV-1, Channel One Russia, BBC One, BBC Two, BBC Four, BBC News Channel, RTE One, Rede Globo, Las Estrellas, CBC, NBC, CBS, FX, TBS, E!, Travel Channel, MTV, Cinemax, HBO, NBC Sports Network, CBS Sports Network, Fox Sports 1, ESPN, NHK World, BBC World News, Al Jazeera English, MSNBC, Fox News Channel, CNN, CNN International, National Geographic Channel, History Channel, Discovery Channel, Disney Junior, Nickelodeon, Disney Channel, Cartoon Network, Disney XD, ABS-CBN and Eurosport.

The abbreviation CATV is often used for cable television. It originally stood for Community Access Television or Community Antenna Television, from cable television's origins in 1948. In areas where over-the-air TV reception was limited by distance from transmitters or mountainous terrain, large "community antennas" were constructed, and cable was run from them to individual homes. In 1968 6.4% of Americans had cable television. The number increased to 7.5% in 1978. By 1988 52.8% of all households were using cable. The number further increased to 62.4% in 1994.
