It is a problem that information and an advertisement can be only seen in the idle state of a terminal equipment, resulting in decrease of advertisement value. A time at which an advertiser displays an advertisement to a client can be specified to the client that has its primary object to display, and a schedule of advertisement display is adjusted based on a fee for the advertisement display in a server when a competition of plural advertisers displaying advertisements at the same time or the like occurs, whereby an advertisement is displayed at a client side at a time desired by the advertiser, resulting in provision of a highly effective advertisement.
