The illustrative stories that begin every chapter are fascinating. Anyone who understands analogies and cares about our culture will be puzzled about the new expansions of copyright until decades after an creator's death, apparently because of the influence of a few lobbyists, like Sonny Bono's suddenly bereaved and very sympathetic widow and the apparently "charming" Jack Valenti.

But even more frustrating than companies like Disney trying to kill the public domain access that Disney was founded on, are stories of organizations like the RIAA and MPAA trying to outlaw technology to protect their outdated business models.

I started listening to this book with that "homework" feeling, but I was pleasantly surprised to find that I enjoyed the whole thing.
