The best language is always found in books because it's considered. It's a high language. Sometimes, it is complex and difficult. It's empowering and offers a way to speak about yourself that you don't have if all you are doing is reading the newspaper and watching TV.
So no one should rely on television either for their knowledge of music or for news. There's just more going on. It's an adjunct to the written word, which I think is still the most important thing.
