There are more than enough laws on the books for content producers to protect their efforts.
The issue is that old media want protections that enable them to carry on with business as usual.
It's like Kodak somehow getting laws passed against digital storage for camera's that guarantee them the revenue of selling film for cameras.
Netflix, Apple, Hulu, Pandora, Amazon, HDTracks, B&W Music.... have all shown new business models are not only possible but profitable.
Seemingly a lot of these old guard companies just want to continue being Block Buster Video instead of seeing where the wind is blowing and becoming a Netflix or even RedBox.
