I was wondering what the sales of MP3 players is – are there enough out there to see a change in audio consumption habits? Or, are MP3 players and iPods a niche phenomenon? Some figures and proedictions were reported in Electronic News – MP3 Market to Nearly Quadruple by 2009. These are based on market analysis from iSuppli Corporation which predicts that MP3 player sales will go from 36.8 million units shipped in 2004 to 132 million units shipping in 2009. At that rate I think it safe to say we have a widespread phenomenon. How then will it change audio listening and consumption? Will radio be replaced by podcasts? Will online music stores replace storefronts?
