The present application relates generally to content management (e.g., management of audio, video and/or imagery). One claim recites a method including: tracking up to N identifiers associated with previously accessed content items, where N is an integer, and where each previously accessed content item has an identifier associated therewith; reviewing rendering rules associated with a new content item or with an identifier associated with the new content item; and restricting access to the new content item if the rendering rules are not met or satisfied. The rendering rules include one or more rules allowing access to the new content item if: i) its identifier is one of the N identifiers associated with the previously accessed content items, or ii) less than N content items have been accessed within a predetermined time. Of course, other claims, implementations and embodiments are provided as well.
