Business models are closely related to the technologies available to produce and distribute products and services. Nowhere is this more apparent than the recorded music business, whose foundations since the early 20th century have been based on the technology on hand, from sheet music, to records, tape cas-settes, CDs, and DVDs. And now, the Internet has enabled two new business models: the online store download-and-own model used by Amazon and Apple’s iTunes, where you purchase songs and store them on a computer or devices, and the subscription service model used by Rhap-sody, Pandora, and many others, where for a monthly fee you can listen to an online library of songs streamed to your devices. In this business model you don’t own the music, and if you miss a payment, it’s gone.
