There's several shows pertaining to that now. Not sure all the stations, but, History has the Doomsday Preppers which is quite interesting. There's always been a fairly large number of people doing this. Rule of thumb for everyday'ers is to have 3 days to a week of supplies on hand just for your everyday emergencies, so this could be big for that. And if you look at the Mormons they stock up for about 3 years. So add the doomsdayers and and all those that want to be self sufficient when this country goes belly up for the next crash (that thought has a lot of followers) you have quite a market.
