The BBC and Digital Music News (and I’m sure others as well) have articles about the results of some research by Jupiter Research. The research shows how little iTunes use gets, compared to the number of iPods incirculation and the alternative sources of music to load onto them. The report indicates that people draw the bulk of their music on their iPods from CDs that they own and to an extent P2P file sharing.
The most interesting point that the BeeB highlights is the fact that people who tend to have these devices also tend to purchase more CDs. So, despite the integration of iTunes and iPods – people at the end of the date like to have something real that they can touch and feel.
