METHOD AND SYSTEM FOR DISTRIBUTING ADVERTISEMENTS OVER NETWORK

摘要

A communication terminal transmits a demand for access to a WWW server connected with a network to a relay server in the network. The relay server transmits the access demand to the WWW server and receives display data from the WWW server, and transmits an advertising ID for specifying an advertisement satisfying pre-defined conditions, together with the display data to the communication terminal. This communication terminal displays the display data on the screen and transmits the advertisement data demand containing the advertising ID, as received from the relay server, to an advertisement distribution server through the relay server. The advertisement distribution server transmits, when it receives the advertisement data demand, the advertisement data corresponding to the advertising ID contained in the advertisement data demand, through the relay server to the communication terminal. This communication terminal displays, when it receives the advertisement data, an advertisement corresponding to the advertisement data, together with a screen image corresponding to the display data.
