How rapidly did Wheel take off? It premiered 1/75 and the trial hour shows were 9/75.
I don't know the ratings data off the top of my head, but I recall Roger's recollection is that the Showcase Showdown and specifically the use of an oversized wheel was a direct shot at Wheel.
Another tidbit: 14 of the first 25 contestants to play PG3 made it to the Showcase (not including the tossed 0003D).
So, combining this along with the stats of your other post, while there was an evident disadvantage to being third insofar as how much you could win to qualify for the Showcase, more than half in first five weeks did make it to the Showcase; and this would be reasonable insofar as there would be some losses in the first two games on some occasions.
Not much in the half hour format you could do since the third game was the last, but this begs the question: If you're in the Row before the fourth game in the hourlong format, do you throw the One Bid? You know it's likely not going to be a car game, and unless there are losses in the final two games, you may be, at best, setting yourself up as the first or second spinner in the Showcase Showdown. On the other hand, you may not win a succeeding One Bid and be
forever without another chance forced to wait ten years before you can again try.
If anything, the Cullen version started with a bigger bang than TNPiR did with a bigger variety of prizes and a more energetic host off the bat.
Did it, though? I admit my knowledge of the Cullen versions is pretty limited, but I seem to recall some story floating the Internet years ago about it having a disastrous pilot and Bill almost getting choked by his mic cord when it got caught while the turntable spun. Perhaps it was better by day one, but even then, do we know for sure it did have a larger variety of prizes at the start of the run?
Bob had yet to start his opening monologue
On this subject, while I praise the late '70s as being the peak of the show's golden era, one thing that definitely got better later on was when Barker starting opening the show with true monologue. The fare in the '70s was often along the lines of, "Welcome to The Price Is Right! If you're looking for excitement, you've come to the right place because over the next hour, we are going to try to give away thousands of dollars in cash and prizes to this studio audience!", which is very stereotypical game show host cringe. Sardonic as Barker was in the '80s, the opening monologue was a definite highlight of the show (and I find it impressive how Barker more or less improvised his monologues, yet it was no secret that Richard Dawson had a writer for his opening bits on Family Feud, and well... they weren't nearly as entertaining).
