The program retrieval support device includes the following units. A program-information-accumulation unit (102) accumulates pieces of program information. A program-search-criterion-input unit (101) receives from a user a search criterion. A program-information-search unit (103) searches the pieces of program information accumulated in the program-information-accumulation unit (102) using the received search criterion. A program-information-display unit (104) displays a list of pieces of program information found by the search. A program-information-user-selection unit (105) receives from the user an input of pointing (selecting) a piece of program information from the displayed pieces of program information. A program-search-criterion-generation unit (106) determines whether or not the pointed program is a major program and if the pointed program is a major program then generating new search criteria for narrowing down the search range to be more similar to the selected program. A program-search-criterion-display unit (107) displays the generated new search criteria.
