In recent years televission has become the most popular form of entertainment.It does not look as if it will be less popular than ever,New systems of television have been made possible by the discovery of laser.
A laser is a beam of light that has many strange qualities.By using a laser it is possible to throw very large and very clear pictures onto a screen.there may be as large as three meters.many people could watch this kind of television together.
;aser beams have also made very thin television sets possible.these sets can be hung on the wall of a room like a large picture.Another development in the future will be three-dimensional television,the picture will look more"real".
In the near future you will be able to buy your favorite television programs already recorded on tapes.they will be like the tapes that are used in recorders today.you will also be able to record television programs and play them back later.the laser beam will make this possible.
