Abstract
A server computer stores user favorites information that relates to the favorites of a user. Whether digital information that has newly occurred on a network suits the favorites of the user is judged based on the user favorites information. If it is judged that there exists digital information that suits the favorites of the user, the server computer informs the user of the new establishment of the digital information that suits the favorites of the user by transmitting E-mail to the user. When a browsing request of the digital information is made by the user, the server computer delivers the digital information to the user and stores history information relating to a history of the digital information that has been delivered to the user. Thereafter, the server computer updates the user favorites information based on the history information.
