INTRODUCTION
1.1    Background of the Study
The word “television” is derived from mixed Latin and Greek word meaning “far sight”. It is a widely used telecommunication used for transmitting and receiving images, either monochromatic (black and white) or colored, usually accompanied by sound. According to (Ogbuoshi, 2005), “Television is an electronic system that is used to convert moving images and sound into electric signal, which are then transmitted by radio waves or by cable to a distance that convert the signal back to images and sound”. He also defined television “as a system for transmitting moving pictures of a scene over long distances by radio and reproduced on receiving instruments”. When news or any speech is made the person reading or making the speech can be seen over the television screen. A television camera changes the area of light and shade in a picture into electric currents of different strengths. The currents are transmitted by the radio and they are picked up by a receiver.
The receiver changes them back into the areas of light shade, which appears as a picture  on the screen of a television set. The television has the ability to communicate simultaneously through sounds and pictures. It shows immediately realities of what is happening at the time it is happening and this makes it the darling of the household members and hastens the learning process if effectively used. (Antonoff, Michael 2009), defines television “as a system of sending receiving pictures and sounds by means of electronic signals transmitted through wires and optical fibers or by electromagnetic radiation.
