The decline in the sales of music compact disks (CD) due to piracy is discussed. It is shown that music sales increased during the early 20th century, but dropped sharply in 1921. At the time, the music industry attributed this decline to the rise of radio stations, which were threatened with prosecution in 1923. Record sales increased during World War II, but declined again in the late 1940s and early 1950s due to conjunction with the television.
