Random musing

I was at the library checking out some DVDs and CDs, when this thought struck me: the most difficult thing here to pirate is the books themselves. It's relatively cheap and easy to rip movies and music nowadays, but to copy a book? It would just be too expensive and time consuming to do so and that's not even taking into account the copy's quality. Who would have thunk it? The oldest mass media is also the best copy protected.
