[1][2] CBC management originally intended to combine Program X with another new production, Canadian Short Stories, to form a common Theatre Canada series despite the radically different concepts of each production.
However, the Dominion Drama Festival intended to rename itself Theatre Canada and objected to CBC's plan.
Theatre Canada was subtitled Canadian Short Stories and aired Thursday evenings from September 1971 as a separate series which was replaced by Program X in that time slot from December 1971.
[2] This half-hour series was broadcast as follows (times in North American Eastern): James W. Nichol and Mavor Moore wrote other episodes of Program X, while directors during the series included David Cronenberg, George Jonas and Lorne Michaels.
[1] A film by David Acomba was scheduled for Program X but withdrawn from broadcast ostensibly due to a failure to meet "broadcast standards", although media suggested the possibility of intervention by the Ontario Provincial Police in this case.
