<p>There is provided a new content distribution technique. A document processing device (100) functions as a browser for reading a document held in a web server (25), acquires a document from the web server (25) via the Internet (29), and displays it. A mode detection unit (78) detects that mode is shifted to a mode for performing a work having an additional value other than the display such as web page edition, printing, copying a part so as to re-use the web page by a user. Here, an advertisement display unit (79) displays an additional content such as an advertisement. There is suggested such a business model that when the mode is shifted to a mode for the user to re-use the content, instead of requiring consideration, an advertisement is displayed.</p> |
