When a book is specified using a review recorded in the review storage unit (24), the control unit (21) specifies a viewable range that is more expanded than normal, and provides a sample page. In addition, when there is a review post, the control unit (21), in the distribution list storage unit (25), expands the viewing range of a review poster. When content is purchased using a review, or when the total number of viewers who have used a review is greater than a reference number of views, the control unit (21) expands the viewing range of the review poster in the distribution list storage unit (25).</p> |
