The practice of television executives of ordering dozens of pilots for proposed television series each year – far more than their networks could possibly broadcast as series – created a sizable body of unsold pilots that had never aired. Packaging these unsold pilots in anthology series and airing them during the summerprovidedtelevision networks with a way of both providing fresh programming during the summer rerun season and recouping at least some of the expense of producing them. Westinghouse Preview Theatre was one of these series, aired by NBC in the summer of 1961. It consisted of 10 unsold pilots for situation comedies and one musical program.
