Digital Rights Management (generally abbreviated to DRM) is term that refers to any of several technologies used by publishers or copyright owners to control access to and usage of digital music or video. This measure tends to protect the authors rights.
For example, when you buy a song with iTunes, you can only listen to it with 3 different computers. But if you download the same song from a peer to peer network, you’ll be able to listen it on as much computers or iPod as you want.
So in my opinion, the most affected are the donwloaders, because they can’t anymore share the files, and use the content they bought like they want.
