Maybe this is just a silly technicality, but still something I've wondered about.
Both TPiR and WoF have, at various points, laid claim to the title of "America's Most Popular Game Show," or at least different TV tie-in products have referred to those shows as such.
Wheel, of course, is commonly the #1-rated show in syndication, despite the fact that its star seems to have burned out slightly since hitting its peak in the 80s.
On the other hand, Price's ratings aren't all that hot by daytime network TV standards, but the show has been on for 32 years and counting, 12 years longer than WoF (well, 3 years if you count the daytime version, but that of course is not continuous)...so obviously someone is still watching. (The Million Dollar Spectaculars are a different matter entirely.)
So, essentially, the question comes down to which is a more accurate measure of popularity--ratings or longevity?
