A delivery mechanism for distributing media items to subscribers uses a timed based benchmark, or a triggering event, in lieu of or in addition to a conventional capacity driven model. In this manner, subscribers can temporarily have access to a number of titles exceeding a quota in some instances, in order to reduce monitoring requirements, or further some promotional interest. In other instances subscribers are consulted in advance before new titles are delivered, to give them an option of selecting their choice or a choice made automatically for them by a recommender system.
