Abstract
The electronic media distribution system which facilitates the distribution of media to consumers over a network, such as the Internet, while achieving commercial business objectives and protecting the intellectual property rights associated with the media being distributed. One such media distributed by the system is musical content. The system provides the infrastructure and support for various market participants to engage in buying, selling, finding and distributing music. Content owners, distributors, retailers (112) and consumers (114) are all market participants. The system provides an interface for consumers to locate, access and receive musical content (120) over the Internet. The system facilitates continued control over the musical content (110) sent to consumers (114) by dynamically enforcing retailer agreements and restrictions governing the purchase, use and distribution of the content. The system also provides a service to retailers and distributors in assisting with the management of sales and distribution of music over the Internet.
