90% of music is still purchased on CDs

A piece of evidence that Mark Cuban is right that TV won't be replaced by TV (at least not anytime soon): Even though digital music is pretty popular, 90% of all music is still purchased on CDs. Reed Hastings mentioned this in a recent interview that he did. This is same reason why I think that good old PVRs and TV time-shifting technologies are going to be around for a long time to come, even though TV shows are increasingly available online through channels like AOL's In2TV and Apple's iTunes.
