When did Major Movie Studios begin using CP?

Does anybody know when the major hollywood movie studios began using copy protection on their DVD’s?

:sad:

Welcome to CDF,
It all started way back with VHS tapes and Macrovision. Most DVD’s have had some sort of copy protection since the beginning.

Here’s a link to Wikipedia introducing Content Scramble System (CSS).

Really old disney tapes used it. We learned that trying to transfer them to DVD. :sad:
