Abstract: A server included in a meeting support system plays back a content correlated with a meeting, and synchronously distributes a playback result to a plurality of terminal devices. The server stores a time the meeting is held, the content played back in the meeting, and a user who participates in the meeting in a memory as a meeting history in each meeting. The server transfers information about the meeting that an assigned user participates in and the content played back in the meeting in order to present the information in the terminal device in accordance with user assignment received from the terminal device. The information is registered in the meeting history.
