An electronic program guide (EPG) having a grid-guide menu and multiple-level nested cascading menus, each cascading menu is adapted to be overlaid upon a current page of the grid-guide menu. During navigation, within a selected multiple-level nested cascading menu, a nested, cascading category-tree of submenus appear and are overlaid upon the current page of the grid-guide menu, until the nested, cascading category-tree is exhausted. A remote control device permits navigating within the grid-guide menu and the multiple-level nested cascading menus. Additionally, the remote control interacts with the EPG to effectuate multiple program selections during the current grid-guide menu during a single selection sequence.
