The death of the CD

Among the details of an L.A. Times report: 48 percent of teenagers bought zero CDs in 2007.

The report, which involved 5,000 people who answered questions online, highlighted a generational split. The increase in legal online sales was driven by people 36 to 50, the report said, giving the music industry an opportunity to target these customers by tapping into its older catalogs.

That’s not to say iTunes is not popular with the younger set. Mallory Portillo, 24, an executive assistant in Santa Monica, said she hadn’t bought a CD in five years, but typically spent more than $100 a month buying music online. She will turn to illegal music sharing sites only if she can’t find new releases or more obscure music on iTunes, she said.
