The internet music market is a new profit-making entity and is growing rapidly due to its extension into the mobile device market. Introduction of the portable multimedia player (PMP), which is the next generation of MP3-players, will influence a customer’s audio and video service preference. The internet music market needs to develop a new business model (BM) for PMPs. This article examines new BMs for customer preference via a conjoint analysis.
