Abstract

A system and method for implementing an electronic programming guide that allows a television viewer to access and interact with television scheduling information. The electronic programming guide provides the viewer with a grid which lists channels, titles and show times. To help the viewer locate information about shows the viewer is interested in, the guide can filter the data prior to display. Only the data that meets certain filter criteria will be displayed. The filter criteria are set by the viewer. The filter criteria can be changed by manipulating a variable selection element such as a slider.
