Startup Idea : Online Game Show Video Competitions

I want to be on a game show and win huge prizes. Lots of other people do as well. We can create a game show presented online. Upload videos into certain competition categories and vote on top performers. Say I want to be the best in the world at billiards trick shots. I send in my videos and try to get votes. If someone does something better than me, I try to do something even better. There could be sponsors of certain competitions e.g. Who can eat a box of Oreos the most creative way? Who can use the ShamWow to clean the dirtiest thing? People can create their own categories and monetize their videos/category with ads like YouTube. Or the site could set up prizes from its own profits. It could potentially be made into a TV show like Ridiculousness and American Idol rolled into one: live audiences plus viewers voting on winners as they watch internet videos.
