As a viewer navigates the hierarchical tree structure provided by program guide 100, any suitable number of levels 105 may be displayed to the viewer. Further, the viewer may encounter a number of levels 105 while navigating one path through the program guide 100, while the viewer may encounter a different number of levels 105 while navigating a second path in the program guide 100.

  • Each content selection 190 may identify a specific television program or programming event or, alternatively, a content selection 190 may correspond to a television channel.
  • each content selection 190 may be represented by any suitable image or shape - e.g., a rectangle, a square, a circle, an oval (or ellipse), a triangle, or a parallelogram - that is presented using a solid, dashed, hidden, dotted, or double line, or any other suitable lines and/or symbols.
  • a branch 102 may couple a category (or content selection) with the upper level category with which it is associated.
  • a branch 102 may also interconnect all of the categories and/or content selections at a level being displayed to the viewer.
  • a "branch” refers to any viewable element indicating an association between a content selection and an upper level category, between a category and another upper level category, between two or more content selections at the same level, and/or between two or more categories at the same level.
