Whole DRM ruleset is getting too oldfashioned IMO - specially now that we have the internet. Music, movies and games are the biggest targets obviously, but it seems that it's only the game side which actually adapts with the technology. Movie and music industry remains rather oldfashioned and behind in times and instead of really adapting they shout and scream at people who download from the internet and whine about millions lost.
Authors aren't really too threatened IMO because whilst it is rather easy to scan and upload a book, nothing still beats reading the good old fashioned way.
