I think if people realized that many great TV shows and movies get their inspiration from books, and that by reading those books they can get so much more out of a story, it would be much easier to convince people to read. When I find out there's a book that a film or show is based on, I make every effort to read it especially if I like the show. But you're right, it's much easier to watch something passively than actively read a page and process the info. I think I'll always love it though.
