A method and a system of recommending media content on a media system (109) by use of a user's interest profile, implicit feedback from the user and the reliability of the feedback: The media system can be a set-top box, a TV, a PC, a DVD player, a radio or a VCR. The media system receives inputs to the media system by use of a keyboard, a mouse, a remote control, an interactive menu, a microphone, gesture recognition or a joystick. The method includes the steps of retrieving information about media content, retrieving feedback information about a user's interaction with the media system (implicit feedback), retrieving feedback information about a user's rating of the media content (explicit feedback), updating the interest profile in response to the feedback information, estimating a score that represents reliability of the user's rating of the media content in response to at least one of the retrieved feedback information about the user's rating of the media content, and using the users rating, the score and a score of the interest profile to modify the interest profile.
