Introduction: television is one of the most wonderful inventions of modern science. It is a great improvement over the radio. Radio pleases the only sense of hearing but television pleases our senses of sight and hearing at the same time.
How it works: two things work behind television – (1) transmission of sound and (2) transmission of the picture. The problem of sending and receiving sound has been solved earlier as in the case of radio. Like sound, a picture is scanned to break it up into small elements of light and shade which are transformed into electric current by cathode ‘Ray Tube’. These ‘light waves’ thus formed are received by the receiving sets of television where through the mechanical process they are recharged and transformed into the image of the original picture.
Variety: like photography, television can be both black and white coloured. Television screen can be different sizes, such as 14 inches, 16 inches, 17 inches, 20 inches, 21, 24, 29, 30, 32 even 74 inches. Recently modern scientist have invented tiny and flat screen television. Television has also various forms and designs. Nowadays televisions are enriched 2/3 windows, games purposes, CD movie player system etc.
As mass media: Television is powerful mass media like internet, newspaper, mobile, etc. It broadcasts news and informs on national and international aspects. It refreshes our mind and focuses on the thought of the whole nation. It also highlights the on-going public concerns. So, as mass media, television has got much popularity.
Recreation/As an entertainer: Television serves as a means for our recreation. After day’s work, we sit before a television set and enjoy songs, dances, plays, movies, dramas, films etc. we feel that the artists have come to our drawing room in order to entertain us.
Its educative values: television has a great educative value. It is one of the most powerful mass media. This is used to teach the uneducated people and the students. Lectures on various topics, lessons on science through television help our young people. So, the educative value of television should also be kept in mind.
Disadvantages: television has also some bad sides. Sometimes naked films and violence are shown. So, our young generation is spoilt by watching the bad scenes. They forget everything and concentrate their attention on it.
Conclusion: Everything has its merits and demerits. But it is the most up-to-date means of communication. As a medium of mass communication, it has proved its superiority over newspaper, radio and other means. But television is a costly instrument. So, in our country, only a few rich persons can buy it. But days are coming when television will become familiar as a radio set.
