Also things must have been relaxed a bit for the Bob Warman version as I’m sure I’ve seen the wheel was back for that. I guess Wheel of Fortune was probably on air by this time so it would be pretty hard to argue against or maybe different regulation for satellite channels at the time?
That's right, anything went on Sky in those days - there's an episode on YouTube which is stuffed with product placement, and the wheel itself is sponsored.
They did a couple of different games in the Crowther era to decide who went to the Showcase, I always remember the Supermarket game where they'd all be challenged to choose a selection of items up to a given total. I always remember this because some of our toys for years after had stickers attached to them with a price because we'd used them to play our own version of Supermarket. What great kids we were.
Then after that, circa 1986 (as I found an episode from that year on a collection of old videos I acquired) they did a different game where the six contestants were asked how much things cost in the past, with the furthest away being eliminated each time until they were down to the final two.
I like how on the Wikipedia page they always refer to Range Finder as if it's a game in itself, rather than a piece of gaming equipment. It's like referring to a round of Bullseye as Dartboard.
