A video distribution system according to an embodiment of the present invention comprises a video distribution server and a user terminal, in which the server provides a live video distribution service for distributing and viewing live video to a user via the user terminal. The system is configured such that the distribution screen presented to the distributor of the live video has a comment display area for displaying at least part of the comment group including comments from viewers, and the display mode is based on at least the number of hidden subsequent comments whose order of posting is later than that of the displayed portion of the comment group displayed in that area. Therefore, when the distributor responds to a displayed comment, the distributor can obtain information based on the number of hidden subsequent comments whose order of posting is later than that of this comment.
