PROBLEM TO BE SOLVED: To provide a trading system or the like for time series information, capable of selling parts of articles, such as serials of a magazine along the time series, in a lump at a relatively low cost. SOLUTION: This trading system comprises the server device of a publishing company 201, the reading devices of a reader 202, and a financial agency 203. When the magazine is newly published, a reader acquires a yearly schedule, decides a purchase article in the magazine according to the schedule, and places orders to the publishing company side. The reader pays the charge to the publishing company side through the financial agency. Each time the magazine is published subsequently, the ordered purchase article is transmitted to the reader from the publishing company. |
