CD protection

I wonder if someone has the numbers of CD protection market or DVD protection market.
It is a good start to my study.
Thanks

Perhaps the StarForce Reviews are a good start?

Starting from February, 2003, our company publishes a newspaper “Copy Protection Review”, which covers copy protection, software piracy and CD-ROM/DVD-ROM/CD-R production issues.
