A system is provided in which an interactive television program guide is implemented on user television equipment such as a set-top box. The program guide provides an operator showcase in the form of one or more operator showcase television listings screens, each of which contains a set of television listings information. The sets of television listings information are generated by querying a database of television listings data in a database in the set-top box. Each database query is based on content criteria previously selected by the cable system operator or other service provider. The service provider is also able to define the format with which the television listings information is displayed in the television listings screens. A title and logos may also be selected by the service provider for each screen. The operator showcase television listings screens may therefore by customized and branded by the service provider. The user may access multiple operator showcase television listings screens using a centralized operator showcase menu.
