Preview Tonight is an American anthology television series that aired on ABC in the summer of 1966.
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.
[1] Packaging these unsold pilots in anthology series and airing them during the summer provided television 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.
[1] Stars appearing in the series included Van Williams, Hal Holbrook, Jessica Walter, Robert Reed, and Bert Convy.
[1] Preview Tonight ran for five episodes over the course of five consecutive weeks in the summer of 1966, airing on ABC from 8:00 to 9:00 p.m. Eastern Time on Sunday evenings.
