I also think whether TV is good or not depends on how to see it. TV is a good tool for us to get information, especially news, and we can know the incidents all over the world through the images. It's important for us. If we heard an affair, we might not think it seriously. However, we can think seriously by seeing images. (In my case, I had a big impact when I saw the image of 9.11. If I only heard it, I wouldn't have believed it.) Although all information are not always reliable, we can think events for real through TV.
I think also TV reflects the climate of our society in some degree because producers are also living our time, and make programs to have many people seen. If there are many entertainment programs now, it says that a lot of people want to see those. I think TV is a kind of each country's culture.
