Abstract: There is provided an information processing apparatus including a content information acquisition part configured to acquire pieces of content information extracted based on an extraction condition, and a display controller configured to cause content icons corresponding to the pieces of content information, respectively, to be displayed on a track placed around a region. In a first display stage, the display controller causes the content icons to be displayed sequentially on a first track in a manner that the content icons appear at a first point on the first track and disappear at a second point on the first track, the second point being different from the first point, and, in a second display stage, the display controller causes a predetermined number of the content icons corresponding to the pieces of content information, respectively, to be displayed on a second track.
