The iPod's continued success goes far beyond the product to encompass multiple types of innovation that helped to create and over time defend the sources of value.
1. Business model-sell songs for 99 cents, instead of whole albums
2. Networking-relationships with music companies, movie studios, television studios, universities
3. Enabling Process-digital rights management software (DRM) that prevents file copying
4. Product Performance-Design language of extreme simplicity is used across Apple's products
5. Product System-Inherent interoperability between devices and the online platform; defended by the DRM software that creates a dependency on playing purchased music on the proprietary product line
6. Channel-the iTunes Store
7. Brand-managing the portfolio of "i" products as a consistent sub-brand
8. Customer Experience-shift from being the hub of the digital home to the hub of the digital lifestyle; promise of a seamless, interoperable, beautiful product.
