On the one hand I understand that the circumstances of the respective markets (movies vs. other media) aren't directly comparable, but on the other hand
- eBooks are often (though not always) available without DRM
- to the extent that music is still sold instead of being streamed, no-DRM is more or less universal
The eBook market is different, because its economics are different.
Piracy costs video producers (TV, movies) more because the cost of production is higher, they spend way more in marketing, and most importantly, their power to set licensing fees for that IP is greatly diminished.
Books for the most part are cheap for publishers to make and distribute; no one is getting $10m advances for a mansuscript. Yet they still charge $10 or more for the digital version!
