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] Along with Preview Tonight, Summer Fun was one of two such series ABC aired in the summer of 1966,[1] and it consisted entirely of unsold pilots for situation comedies, some prepared for the 1965–66 and 1966–67 seasons and most shot in color.

[2] Stars appearing in the series included Joan Blondell, Tom Ewell, Shelley Fabares, Celeste Holm, Bert Lahr, Basil Rathbone, and Jon Voight.

[1] Summer Fun ran for seven episodes over the course of seven consecutive weeks in the summer of 1966, airing on ABC from 8:00 to 8:30 p.m. Eastern Time on Friday evenings.
