I would have to think a few things have contributed to the demise of the old thrill show....the one off stunts that people book tend to be a bit cheaper and more interesting to spectators, but I think the Xgames has been a big contributor to the lack of interest. I mean once you have seen some guy backflip a motorcycle across a 100 foot gap with all his limbs hanging off the bike do you really get excited by a couple cars doing zigzags and driving on 2 wheels?
