Philip Roth predicts novel will be minority cult

The Guardian online has a story about how novelist Philip Roth predicts novel will be minority cult. According to the story by Alison Flood (Monday 26th of October, 2009),

He said it was “the print that’s the problem, it’s the book, the object itself”. “To read a novel requires a certain amount of concentration, focus, devotion to the reading. If you read a novel in more than two weeks you don’t read the novel really. So I think that kind of concentration and focus and attentiveness is hard to come by – it’s hard to find huge numbers of people, large numbers of people, significant numbers of people, who have those qualities,” he said.

I wonder if it true that screens take less concentration than books. I can believe it about television, but not about doing things on the screen like programming or even playing a console game. I can finish most books much faster and with less hard work than playing a console game (which may say something about my gaming skills.) Is it really the form of the object (screen vs book) or the content (typical TV show vs difficult novel)?
