Watermarking takes its first steps

Mediaweek: Nielsen offers protection to copyright holders
Nielsen is expected to introduce a digital watermarking service to protect copyrighted video content from being pirated online. While other companies have ventured into video copyright protection, Nielsen has a leg up on potential rivals because it is responsible for encoding almost all network TV programs as part of its ratings service.

Watermarking fun
Good one Nielsen.
As long as you only track information and don't damage the user experience, I'll love you even more.
My chipmunk might even write a rap for you.
