Cable television
1. Cable television is a system of providing television to consumers via radio frequency signals transmitted to televisions through optical fibers or coaxial cables as opposed to the over-the-air method used in traditional television broadcasting (via radio waves) in which a television antenna is required.
2. The abbreviation CATV is often used to mean «Cable TV». It originally stood for Community Antenna Television, from cable television's origins in 1948. In areas where over-the-air reception was limited by distance from transmitters or mountainous terrain, large «community antennas» were constructed, and cable was run from them to individual homes.
3. It is most commonplace in North America, Europe, Australia and East Asia, though it is present in many other countries, mainly in South America and the Middle East. Cable TV has had little success in Africa, as it is not cost-effective to lay cables in sparsely populated areas. So-called «wireless cable» or microwave-based systems are used instead.
