The program guide server may provide program guide data, schedules reminders, schedules program recordings, and parental locks programs on the basis of the expressions. Users' viewing histories may be tracked. The program guide server may analyze the viewing histories and generates viewing recommendations, targets advertising, and collects program rating information on the basis of the viewing histories.
