Compact disc
The compact disc format replaced both the vinyl record and the cassette as the standard for the commercial mass-market distribution of physical music albums. After the introduction of music downloading and MP3 players such as the iPod, US album sales dropped 54.6% from 2001 to 2009. The CD is a digital data storage device which permits digital recording technology to be used to record and play-back the recorded music.
