Abstract

The present invention provides a content search and display system capable of increasing opportunities for the user to encounter more unknown contents than ever. Operating situation detecting means 25 detects an operating situation of search condition specifying means 15. According to the operating situation of the search condition specifying means 15, condition adding/modifying means 27 adds or modifies a search condition. In the course of searching, opportunities are produced for the user to encounter unexpected unknown contents not randomly, but based on a certain search condition, by operating the search condition specifying means 15.
