I happened to come across some TV listings from April 1976, in my hometown newspaper in Regina, Canada. They listed The Price is Right airing in a half hour format, five days a week, at 4:30 pm on CKCK, the local CTV affiliate.
Curiosity gets the better of me here. In April of 76, Daytime Price had gone to its one hour format, and Nighttime Price was once a week. So are they airing old episodes of the daytime show here? Reruns of the nighttime show, perhaps?
(Incidentally, I believe this is the ONLY time a local station in Regina ever aired the show in its 36 years. In the 1980s we received a CBC affiliate from Yorkton, Sask., that was airing the show at 5pm, though.)
