+For audio, the logo "Compact Disc Digital Audio" is actually owned by Philips and licensed for use by manufacturers who meet the RedBook standard for digital audio. Many forms of CopyControl degrade the audio quality or alter the data structures on the plastic wafer in an attempt to prevent customers using the data. By thus degrading their product, the manufacturers may no longer meet the RedBook standard, meaning they cannot ''legally'' be called CompactDisc~s.
+Since consumers might notice that plastic wafers which do not work in their equipment are missing the "CD" logo and so stop bying such CopyControl~led wafers, there is an incentive for manufacturers to mislabel their discs.
