How about an invention program. Amateur inventors who have an idea to improve the world (not just a home gadget for selling, but something that will actually benefit the world), wo try to win a grant to but their idea into action.
I really think that we should get back to the basics and give the public simple TV Shows like Streets of San Francisco and Happy Days that gave us entertainment instead and creating problems for contestants. Take Biggest Loser fort example. If you are responding to the diets etc and losing weight you're voted off because you're a threat. Surely they could make it so that the lowest loser for the week goes and they would know that and out in harder and stick to the diet and do their best to stay. It's like knowing that if they don't apply themselves they are gone.
