Abstract
A method and structure is capable of scanning through available programs on a display screen and selectively displaying the most recently scanned programs in a spiral formation on the display screen. The spiral formation conveys visual information to the viewer about when the programs were scanned by the arrangement and sizing of a number of positions of the spiral formation. Provided with the visual information of the recently scanned programs in the spiral formation, the viewer can readily determine which programs were recently scanned and when they were scanned.
