Function
-
The main use of cable TV lines is to transmit information from one point to another. The information can be in the form of television broadcasts, broadband Internet or telephone services. Because of its durability, cable TV lines allow for clear transmissions that are not generally interrupted due to storms or other natural disasters. Other traditional means of transmitting information such as telephone lines use thin wires that can be knocked down by heavy winds. Cable TV lines have large copper wires with a dielectric insulator, surrounded by a layer of metal mesh and plastic. In addition, they are commonly run underground, giving added protection from the elements.
Features
-
Cable TV lines use a signal transmitted from a central source, usually the cable provider company. This signal travels across its wires to a central routing box located on a city block or within a building. This box sends the signal through more cable TV line to individual receiver boxes. These boxes send a signal using a coaxial cable that contains a silver or nickel tip that attaches to a television or modem. HD televisions use an additionall HD cable to send the signal.

These lines are installed and maintained by professionals who work for the cable provider company. These professionals range in duties from simple installations to laying the wires for new construction zones.
Significance

The companies have used the lines to create a industry of cable television programs with thousands of channels available nationwide. In addition, the lines can transmit information at a faster speed and larger quantity than other means, making their use for Internet access very sought after.
History
-
The first cable TV lines were invented in the 1940s; however, public use was limited as television had yet to become a viable form of communication. By the 1970s, demand for better quality transmissions and increased interest in additional television stations became apparent to the industry. Until this point, the only way to receive television signals was through analog broadcasts picked up by antennae. Cable TV lines began to be laid in large metropolitan areas and subscription services were introduced. By the 1980s, cable TV lines had spread to the suburbs and large towns throughout the U.S. New networks were created to make use of the infrastructure. In the early part of the 21st century, telephone and Internet services were introduced to consumers. The cable TV lines became an all-inclusive form of communication transmissions.
