ABSTRACT
Cable News Network [abbreviated as CNN] international news broadcasting company, based in the United States and founded in 1980, which was the first to introduce 24-hour news coverage
cable telephony telephone service offered by a cable television company
cable television television service via cable. Cable television was first used
in the late 1940s in order to broadcast television signals to places that either could not receive them through the air, or who could receive them only with much
interference. Some cable systems carry more than 100 channels; this large number has made NARROWCASTING possible. Unlike broadcasting, which tries to appeal to the largest possible audience, narrowcasting offers programs that appeal to a particular interest. Cable channels may specialize in news, movies, comedy, science, music, health, religion, weather, and so on. Customers pay a monthly fee for service, plus additional fees for certain channels. Most cable services also offer one or more channels that make movies or special events available on a pay-per-view basis. These can be ordered either by telephone or through a set-top box.
