Abstract: In an inherited communication management apparatus, a storage unit stores viewing information relating to the content viewing state of a user of a terminal. On a request from the user of the terminal for content viewing, a requesting unit requests another inherited communication management apparatus to examine whether or not the other inherited communication management apparatus stores viewing information including information relating to interruption of the content viewing by the user. A receiving unit receives a result of the examination requested by the requesting unit. When the examination result received by the receiving unit includes the viewing information including information relating to the interruption of the content viewing, a transmitting unit transmits information relating to interrupted content based on the viewing information to the terminal of the user that has requested the content viewing.
