Invention itself has done nothing wrong TV is a great invention which can’t be denied by any of us. Although there are many people insisting that TV has proved to be one of the worst inventions of modern times, I still have to argue: invention itself has done nothing wrong. Right after the web TV appeared, people seemed to begin listing all the disadvantages TV has. Why don’t we look back into the times when there was no web TV, no WIFI, and there was only TV which was the most modernized tool for entertainment. TV made our lives much easier and much more convenient that we could know the news happening around the world without leaving home. We have various TV programs to choose from, which again makes people worry that some of them would be harmful. We’d better think in this way, also because of so many choices, we become selective and are able to get rid of those which may do harm to our daily lives. Moreover, in recent years, SARFT is trying very hard to give those programs strict examinations to pick out the right ones for people to watch, and tough censorships have come out to make sure that the TV programs will be healthier. For kids, parents should make strict rules about what their children are going to watch and how long they are permitted to stay in front of TV, thus encouraging kids to develop a good habit of watching the right program at the right time, which can also reduce the harm TV may do to them. The convenience TV has brought us shouldn’t be denied just because of the improper use it has been made of. Whether an invention like TV is harmful or not depends on how people treat and use it, and there is nothing wrong with the invention itself at all.
