We are going to talk about the history and origin on how cable television was built, created, and invented for pure home entertainment and fun. Let's get on to this topic now, as we're going to know everything about cable television for good.Cable TV originated in the late 1940 in United States. Cable TV got its demand from places where people could not receive TV stations through an antenna. Therefore, Community Antenna Television or CATV got its birth. Mr. John Walson, storeowner of appliances in the town of Mahanoy City, Pennsylvania had discovered the birth of Cable TV. 

He had started selling television sets but there was no reception of programs at that time. Then, Mr. Walson had put up a TV antenna on top and a utility pole on top of the mountain.Signals for television had started receiving which got transferred to twin lead antenna wire down to his store. Thus came the age of buying television sets and soon the signals were started to get improved. To improve the signals and quality of the picture, coaxial cables were used. This was first discovered and implemented in June 1948. By 1962, around 800 cable systems started serving and gained a business of some 850 thousands subscribers.In the year 1972, Pay Television was launched and Service Electric introduced Home Box Office or HBO, over the cable system in Pennsylvania. By the year, 1980 Cable TV soon started airing all over the world. The television industry got a great boom with its spread everywhere. Cable TV also classified the ratings for the viewers according to the age and contents of the program. Some of the classifications are G, PG, 12+, 18+, etc.Channels are too distributed into frequencies and they are modulated with a single cable, enabling the cable operator to divide many channels from a fiber optic to coaxial cable to television sets. CATV helps in connecting Data services, FM Radio and TV channels through one single wire. Therefore, Cable TV industry has given television industry a large number of consumers for the everlasting demand of entertainment with a high quality and an improved technology.
