US Patent 8930977 Tracking user affinity through interactions with media files

A user's interactions with a media player during the playing of a media file may provide a variety of information regarding the user's interests in the media file, or in any objects, images, sounds, individuals, things or themes expressed or described therein. A media player or the software operating thereon may be modified to receive interactions from the user and/or to analyze such interactions in order to associate the user with such objects, images, sounds, individuals, things or themes. The user's interactions may also be analyzed by a media service, an online marketplace or any external location in order to identify any items related to such objects, images, sounds, individuals, things or themes, or for any other purpose.
