An interactive television application such as an interactive television program guide may display screens of program listings for a user. Such program guide screens may include listings for both scheduled program and for programs that are without a scheduled start time. Program listings may be displayed based on time, genre, theme, etc. Menu options may be provided that allow the user to search for video-on-demand programs by title, actor, keyword, genre, etc.
