Television programs are represented by program interface objects (PIOs) within an interactive television system. The program interface objects may be represented by visual indicator for quick identification of the represented television program, one or more attributes providing information concerning the represented television program, and one or more actions that may be performed on or in connection with the represented television program. The PIOs may be sorted, filtered, and/or managed based on user-provided criteria. The PIOs may also be linked to allow an operation performable in connection to one PIO to be performed in connection with the linked PIO(s).
