The issue of DRM is a complex one.  An alliance has been created (The Digital Watermarking Alliance) to promote the value of digital watermarking to content owners, industry, policy makers and consumers.

From their website:

“With movies, music and photos increasingly being distributed and shared digitally across numerous mediums, and printed value documents such as IDs and financial
instruments at risk to counterfeiting, fraud and theft, protecting therights and integrity of these assets and enabling legitimate uses has become critical.
At the same time, consumers are demanding instant access to entertainment content – any time, any place and in any format.”
