As digital music stores become more common and convenient, the age of the compact disc as the preferred medium is coming to a close. In fact, according to year-end sales figures released by The Nielsen Co., sales of CDs are down a whopping 20 percent.
The sales of physical discs have dropped from 450.5 million in 2007 to only 362.6 million in 2008. And during this time, digital album sales made a gigantic jump of 32 percent over their previous year’s sales.
Apple’s iTunes music store has been particularly successful, having broken the 1 billion song mark with 1.07 billion sold. Along with this, their sales went up 27 percent over the previous year.
