Background
The Copy Control protections were devised in response to the file sharing and casual CD copying that has become commonplace in recent years, allegedly causing the music industry significant losses, or "ungained" revenues. Neither issue was particularly relevant when the CD standard was introduced in the early 1980s, and thus, unlike the more recent DVDs, the CD standard specifies no inherent form of copy protection or other digital rights management. Copy Control is one of a number of attempts to apply copy protection on top of the CD standard, but since it is merely a modification of the already unrestricted standard which must still yield usable results in most CD players, the efficacy of the system varies significantly. Nevertheless, EMI's labelling of some Copy Controlled discs attempted to override consumers' statutory rights with the disclaimer "except for defective product resulting from the manufacturing process, no exchange, return or refund is permitted".
As the Copy Control discs do not conform to the requirements of the CD standard, they are not labeled with the CDDA logo, which is trademarked by Philips. A Copy Control "CD" which would not play in a car CD player was deemed "defective" in a French 2003 lawsuit, and every recent Copy Control released disc carries visible Copy Control notices stating merely compatibility with CDs and the possibility of playback problems "on some equipment, for example car CD players". Nevertheless, the discs are frequently referred to as CDs or "copy-protected CDs" in music stores and in colloquial language.

Famous quotes containing the word background:
“I had many problems in my conduct of the office being contrasted with President Kennedys conduct in the office, with my manner of dealing with things and his manner, with my accent and his accent, with my background and his background. He was a great public hero, and anything I did that someone didnt approve of, they would always feel that President Kennedy wouldnt have done that.”
—Lyndon Baines Johnson (19081973)
“Silence is the universal refuge, the sequel to all dull discourses and all foolish acts, a balm to our every chagrin, as welcome after satiety as after disappointment; that background which the painter may not daub, be he master or bungler, and which, however awkward a figure we may have made in the foreground, remains ever our inviolable asylum, where no indignity can assail, no personality can disturb us.”
—Henry David Thoreau (18171862)
“In the true sense ones native land, with its background of tradition, early impressions, reminiscences and other things dear to one, is not enough to make sensitive human beings feel at home.”
—Emma Goldman (18691940)
