A discovery interface facilitates the selection of available media content. Content-relevant graphical tiles are displayed in strips within the discovery interface. In this manner, a user can survey graphics associated with available content. When the discovery interface section (e.g., a row) is in focus, the graphical tiles are expanded as compared to the tiles in sections that are not in focus to provide easier viewing by the user. Furthermore, when an individual tile is in focus, then the tile expands further to be wider and taller than any of the other tiles in the associated tile strip. In one implementation, the focused tile is also highlighted, such as with a distinguishing border. In another implementation, metadata associated with the content of the focused tile is displayed in the proximity of the focused tile.
