Business model for providing articles and advertisements for pay by contents delivery and related information exchange method and system

摘要

A supply side converts, into an information fragment, each of a lot of articles and advertisements provided by publishing sources such as a newspaper company and a plurality of advertisement sources, and codes and delivers the information fragments. The supply side makes a subscription contract including a restricted genre and period with a viewer side via a bidirectional communication medium. The supply side supplies a decoding key that is effective only within the confines of the contract and thereby allows the viewer side to capture and display only information fragments that satisfy the contract. The supply side charges the viewer side for only the captured fragments and collects a fee from the viewer side. Further, on-page advertisement fragments or flier fragments are linked to article fragments so that when an article fragment or an advertisement fragment is captured, the other is also captured and displayed.
