Don’t get why they would tell the audience not to cheer or show emotion when something exciting happens a lot of shows have people hired to get people to do just that hype people I believe they are called. I could see them not wanting something like that in jeopardy because they are trying to recall information about questions Wheel rob maby you could provide some more insight as to why wheel producers run the show like this.
Well, Jeopardy!'s meant to be a subdued, but fast-paced game. But we still of course hear the audience applaud contestants finding the Daily Double (even if they go on to get it wrong), so it's sad to watch classic episodes of Wheel and hear everyone stop for a moment to celebrate the Wheel landing on $1,000 (even if they end up calling a wrong letter), yet today, someone could spin $5,000 five times in a row and it would be treated like $500.
When I was at WOF, I was given two excuses. First, I cheered when someone landed on the Million Dollar Wedge, and was told during the break, "You can't react like that because it looks like you're showing favoritism to one contestant". It was literally the first turn of the game. Then on another episode taped that same day, someone hit the $3500 twice in a row (which led to him winning over $20K in that round alone, which is more than what many winners finish the whole game with) and was told by someone else during the break, "When you scream like that, it messes with the audio." This makes no sense given how loud audiences were in the past, especially when they used to film on location. And look at how crazy Price is Right's audience cheers for things like "Here's $500 for getting the price exactly right", and giving standing ovations for someone winning $1,000, while Wheel's audience just sits and claps politely when people win the million.
That being said, although I've never been to a Jeopardy! taping myself, I read that the audience actually does not clap during the credit roll; it's all added in post-production. I can definitely see Jeopardy!'s staff shushing someone screaming "YEAAAAAHH!!" at a successful true Daily Double, but again, it's a much different atmosphere than someone spinning the top amount multiple times in a row on WOF.
