Remember CCCD? Probably not, unless you collect outdated acronyms.

Between 2002 and 2004 many Japanese record companies released copy-controlled compact discs, aka CCCDs. Tracks from such CDs could not be burned onto PCs or copied onto portable devices such as mp3 players.

But consumers didn't like what they saw as a heavy-handed tactic by Japanese labels, which eventually dumped CCCD.
