If DVDs and Blu-rays were always protected, why is the icon needed?
The motion picture industry wants to make sure that consumers are aware that the DVD and Blu-ray discs they rent or purchase can only be used to play back content on licensed devices, and that they cannot be freely copied. This icon is also part of a larger effort by the motion picture industry to help raise consumer awareness of the need for technical protection of copyrighted content (such as movies and television shows) in the digital age. Use of such technical protections leads to broader availability of high-value, digital content to the consumer.
