The purpose of the invention is to present advertisements properly to users. To realize this, a web server sends necessary related information which includes links for download, to a client machine, in accordance with a download request of the client machine. When the client machine requests start of download, by use of the link, the web server, in response to this, distributes designated predetermined contents and an advertisement supply server distributes predetermined advertisement contents. When there occurs an instruction of forced termination of distribution of advertisement contents by the advertisement supply server, from the client machine, the advertisement distributing server terminates distribution of advertisement contents and sends a forced termination flag which shows forced termination of distribution, to the web server. The web server, in response to reception of the flag, ceases distribution of contents.
