Television has a number of uses. First of all, it makes it possible for us to see what is happening far away. In our homes we watch on television, films or events taking place in other cities, countries and other continents. The artificial satellites have made it possible to watch events in other countries directly. Television is a very fine medium of entertainment. It brings musician and the music, singer and his singing and actor and his acting close to us. Whether it is rain or sunshine, hot or cold, we can enjoy television programmes within four walls of our homes.
Television can be used to teach uneducated people. Through it we can improve knowledge of our students and educated people.we can present on TV educational programmes of different categories.
We can telecast other programmes of general information. For example there can be science programmes about modern inventions. Special economic television programmes can be very useful for general public.through them market rates of different articles can be quoted and explained. Political television programmes are of great importance.they bring political leaders and their views close to people.
We should present such TV programmes which entertain the people in the right way as well as improve their knowledge and character. We should avoid the presentation of programmes that may spoil the taste , character and morale of people.
THE INVENTION OF THE T.V.
The credit as to who was the inventor of modern television really comes down to two different people in two different places both working on the same problem at about the same time: Vladimir Kosma Zworykin, a Russian-born American inventor working for Westinghouse, and Philo Taylor Farnsworth, a privately backed farm boy from the state of Utah.“Zworykin had a patent, but Farnsworth had a picture…”
Zworykin is usually credited as being the father of modern television. This was because the patent for the heart of the TV, the electron scanning tube, was first applied for by Zworykin in 1923, under the name of an iconoscope. The iconoscope was an electronic image scanner - essentially a primitive television camera. Farnsworth was the first of the two inventors to successfully demonstrate the transmission of television signals, which he did on September 7, 1927, using a scanning tube of his own design. Farnsworth received a patent for his electron scanning tube in 1930. Zworykin was not able to duplicate Farnsworth’s achievements until 1934 and his patent for a scanning tube was not issued until 1938. The truth of the matter is this, that while Zworykin applied for the patent for his iconoscope in 1923, the invention was not functional until some years later and all earlier efforts were of such poor quality that Westinghouse officials ordered him to work on something “more useful.”
