US Patent 10390101 Advertisement rotation

A system and method for delivering content over a network is provided. Content may be primary content (e.g., music or a movie) or ancillary content (e.g., an advertisement). The ancillary content may further be classified as universal ancillary content that all users of the present system will receive; targeted ancillary content that particular users of the present system will receive; and context-specific ancillary content that users of the present system and viewing particular primary content will receive. The type of primary and/or ancillary content delivered to the user will depend, in part, on indicia of the user of a device receiving the content. The present invention seeks to ensure that a user has relevant and up-to-date ancillary content notwithstanding the nature or date of the primary content. Feedback data concerning the viewing of the ancillary content may also be generated such that a provider of the advertisement and/or product may provide targeted advertisements and improved products and services.
