Multiple videos in a particular set are distributed for local storage at central offices. Each of the videos is distributed to at least one but not all of the central offices. An order for a selected video from the set is received from a customer served by a first of central offices. If the selected video is not stored by the first central office but is stored by a second of the central offices, the selected video is downloaded from second central office to the first central office, and communicated from the first central office to the customer.
