Information posting system, information posting method, electronic commerce system, electronic commerce method

摘要

An electronic commerce in which the double input of information, the delay of information posting by a mediate information provider and the resultant loss are eliminated when a seller or an information transmitter posts the same information on the Web page of the seller or the transmitter and on the Web page of the mediate information provider. When the seller or the information transmitter transmits information on commodities or services on its Web page or the TV program, a program for assigning an identifier automatically to the detailed content item to be posted is employed to write the information. Thus the information is transmitted as in the prior art to the Web page of the seller or transmitter or the TV program and the Web pages of one or more mediate information providers or the TV program without any additional transfer or error by only a single input and by only a single transmission.
