It was the dish antenna or a disk-like aerial system for TV that was earlier used for receiving signals from TV stations.It was a large concave reflector for the reception of radio waves from outer space or in radio telescopes.Its use in our country was greatly on the rise when the cable was introduced a few years earlier.The cable companies now use very huge and professional antennas with sophisticated(modern and complex) mechanisms and satellite stations to convey the programs of TV stations around the world to TV viewers.The users of the cable are also in the privileged position of benefiting from the Internet for gaining valuable information and enjoying varied entertainment.
The cable and dish antenna are among the latest in the line of electronic developments of the radio,TV,tape recorder and computer.
The positive uses of the cable are many.First of all it helps the distant parts of a country to come closer and get unified in a unique manner.Those living far apart beyond the range of one TV station can watch TV programs of all the stations of the country at the same time(simultaneously) through it instead of depending on satellite communication.Different nations and countries acn watch each other's programs at will any time.This can bring all the countries together and cause them to understand each other's problems and difficulties if only care is taken that TV programs are designed to increase understanding and love between different nations and peoples.
Secondly,the cable has made possible direct communication of news and pictures from one part of the world to all other parts.This role is informative, and it surely replaces that of the newspapers and journals to a great extent.For extremely busy people,some time spent before international Tv program network can be as rewarding as reading lengthy newspaper reports for hours together.
Thirdly,as never before,a ready comparative viewing of TV programs of many countries can be made at one sitting.We can decide which TV station in which country is doing better and in what ways,and so we can watch and to listen best of all.Be it the US,the UK,France,Germany,Italy,Iran,Turkey,Japan,China,the Philippines,Russia or any other country,we can pick and choose the most appealing.The national TV can no more monopolize our time and attention.Nor can any country dominate our culture.
Fourthly,travel,trade,industry all are promoted and expanded by rapid circulation and communication of information regarding atmospheric and travel conditions,market situations, and production processes in operation around the world.We can decide about travel anywhere and make important business plans in view of all that we learn thsu.
