Movies/Music/TV are more portable than games, steam doesn't have to deal with portability (multiple different devices, not explicit PC's that run the games) (yet) which is why it's a good system for what it is. Essentially a Steam for everything would never be able to have DRM otherwise certain devices would get locked out, which returns us to the original problem of DRM. Steam just locked onto a niche market and realized their potential.
