When you switch on the radio, you can listen. But when you use the telephone, not only can you listen to others but also you can chat with them; however, you cant see anything at all. Television is perhaps much better than both of them. People can watch TV and listen to it, but they cannot take part in what they see. Today , some people are using a new type of telephone called vision phone. With it two people who are talking can see each other. Vision phones can be of great use when you have something to show the person whom you are calling. It may also have other uses in the future. Some day you may be able to call up a library and ask to read a book right over your vision phone. You may be able to do the shopping through it too.
