An information processing terminal is connected to an external server via the information sharing system (WEB) so as to implement Twitter, social networking services, and text posting services. The information processing terminal is used to receive a desired content (e.g. a television broadcast content), to browse the posted information posted on the WEB from the external server, to select at least one classified information (e.g. hash tags) used to classify the posted information from among a plurality of classified information, to obtain at least one classified information with reference to the external server, and to simultaneously display at least one classified information linked with the desired content. The information processing terminal simultaneously displays a content display screen used to display the desired content and a posting service display screen used to display a plurality of posted information browsed from the external server.
