Business models are closely related to the technologies available to produce and distribute products and services. Nowhere is this more appar- ent 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.
