@blatham,
The quality of what you are reading/watching is more important than the medium through which you get it (books, TV, internet, etc.). It's entirely possible to read a lot and still remain stuck in the same banalities forever, if all you read comes from the same narrow circle of narrow-minded writers. Likewise, it's perfectly possible to become a very successful individual without reading much, as long as you compensate with other good quality and diverse sources of knowledge.
There are plenty of people on this planet who gather all their knowledge from their own life alone. They don't read, they don't watch TV, they waste no time on Internet. Maybe they listen to the radio a bit. but for the most part they just speak with people around them, and learn from them, and from their own life. These people are often very original in their thinking.
But to come back to TV vs the Internet, I do think that the Internet has changed our rapport to lies and truth, and how lies and truth are spread. In essence, everybody can start his own TV now. In that context, the most successful lies are going to be those coming from a variety of sources, or what pretends to be a variety of sources. Before, one or two TV channels were enough.
