A receiver for receiving a digital radio broadcast in which additional information is multiplexed with audio information includes a memory for storing the additional information, a liquid crystal display (LCD), and a bookmark button. When the bookmark button is depressed during reception of a program, a control unit stores the additional information of the program in the memory as bookmark data. The bookmark data stored in the memory is displayed on the LCD. When data is specified as search data the control unit sequentially searches programs currently being broadcast or to be broadcast, and detects and tunes in to a program that includes the search data in the additional information of the program. Alternatively, the additional information of the detected program is displayed on the LCD and tuning in to the program is performed in accordance with an operation by a user.
