Abstract: User terminals receive multimedia content, such as on-line articles, from a publisher. The user terminals collect statistical data indicating the current popularity of the content with the users, and report the statistical data back to a server associated with the publisher. The server accumulates and periodically analyzes the statistical data and dynamically generates prices for the publisher to charge the advertisers based on this information. Placing advertisements with more popular content, as determined by the statistical data, could cost the advertisers more than placing advertisements with less popular content.

Abstract: A network server implements Digital Rights Management (DRM) techniques to limit or inhibit unauthorized access or usage of protected multimedia content, such as a video or a song. However, the server also allows a user who has purchased protected multimedia content to share that content with one or more other people based on the strength of the user's relationships with those people.
