A prize contest system has user terminals and a prize-offering site. The prize-offering site has databases which store prize information on prizes, an entry-accepted date and advertisement information on a sponsor of the prizes in association with one another. In response to a request made through any user terminal, the prize-offering site sends prize-contest information to that user terminal using the prize information, the advertisement information and information on the entry-accepted date. With regard to ordinary entries, the prize-offering site accepts only those entries which are directed to prizes of that date. With regard to those entries which have keywords shown on an advertisement medium, such as a magazine, the prize-offering site permits entries for prizes whose entry-accepted dates have not come yet.
