Abstract: A broadcast receiving device comprises: a memory medium 403 that stores a received e-mail and broadcast mail, an add-on program 402b for adding an e-mail header to a broadcast mail body text, and a display program 402c that displays a broadcast mail and an e-mail stored in the memory medium 403 on a monitor 407. When a CPU 411 receives the broadcast mail according to the programs, it extracts the broadcast mail body text, adds the e-mail header to the broadcast mail, stores it in the memory medium 403. Then the CPU 411 reads out the information of the broadcast mail and the e-mail stored in the memory medium 403, and displays them in one screen.
