Television is very popular nowadays. We can have a clear idea what is happening in the world. We can have live information about sports events and competitions. One can have a weather forecast and plan several things beforehand. It is also a good source of entertainment which is very cheap. You can watch interesting programs that are both entertaining and useful. If you want to travel but do not have enough money, you can enjoy traveling on TV (for example, watching the Discovery channel or National Geographic channel). There is a scientific channel which is suitable for all ages. That is the fastest and cheapest way to improve your knowledge. However along with some positive sides it has its negative points. Watching too much television is wasting time. Some films are not for all ages. Watching too much television also does harm to your eyes and nerves. Older people lose their own opinion. They feel whatever is being shown on television is correct and should be practiced as such. Nowadays TV is replaced by computer. Children spend too much time at the screen. Parents must always know what programs their children watch on TV or the Internet and how much time they spend doing it.
