Abstract: A storage stores content sets in which, when a preceding content is used, a subsequent content is made available after a lapse of certain time. A provider provides, to a user terminal, an available content that is usable by a user among contents within the content sets. A setter sets, when an unused content not having been used by the user among the available contents is first used, a start date and time at which a subsequent content following after the unused content is made available, in association with the subsequent content. A selector selects, according to time remaining until the set start date and time, at least one recommended content from among the available contents. A generator generates a recommendation list in which the selected recommended content is followed by the subsequent content. A presenter presents the generated recommendation list to the user terminal.
