I think, in my opinion, there have been many survival shows in the last few years, starting with Les Stroud. What I think has fueled these shows is because of the way the World or our Country is heading. I think a lot of people see doom and gloom in coming times. Economic and other things. I said starting with Les Stroud but really it started with the reality shows like Survivor. I dont know how Im trying to say it, but It seems to me these shows are really popular because people want to know how to handle future disasters. We have all heard about the Mayan Callender and we had 9/11. I think thats why these are so popular. Simple fact, people want to learn how to be prepared for the hard times a head. I may be way off on that. If so, sorry.
