I had a great idea for a tv show for adults, a quiz/game show called Inferno. It sounds rather dramatic, but it’s not.
You have a small audience of maybe a hundred or so, mainly young folk. Someone is picked at random to come and answer ten straightforward general knowedge questions.
The first is worth £1, the second £2, the third £4 and so on, doubling each time so the tenth is worth £512. But the sum accumulates, so after two questions you have £3, after three you have £7 and so on, so getting the tenth wins you £1023. Great for maybe a couple of minutes work.
