A computer system includes a touch-screen display that displays an electronic program guide to a user. The EPG includes a list of television programs scheduled to be shown at a current time as well as a timeline and an indicator. The television programs in the EPG have a substantially fixed size, independent of the program duration. The user can adjust the relevant time in the EPG by manipulating the timeline and the indicator so that they slide relative to one another. The EPG is updated to include a list of television programs at a new time according to the new position of the indicator on the timeline. A selectable icon is provided to enable the user to return the EPG to a current time.
