Systems and methods for displaying program guide information are disclosed. In some implementations a method includes, at a computing device having one or more processors and memory storing one or more programs for execution by the one or more processors, formatting, for display, program guide data on a grid. The grid includes (i) a first axis representing units of time and (ii) a second axis representing multimedia channels. The program guide data comprises information representing a set of multimedia events. Responsive to a user-supplied selection of a multimedia event in the set of multimedia events a panel is overlaid on a portion of the grid. The panel provides additional data regarding the multimedia event.
