A content distribution system includes a content distribution server and a portable game terminal. The content distribution server retains a first license for comprehensively permitting the use of multiple digital contents and issues to the portable game terminal a second license for individually permitting the use of a digital content selected by a user from among the multiple digital contents. The portable game terminal retains the second license and permits the use of the selected digital content if it is within the license period of the second license at the time.
