Those shows you mentioned are not reality tv. American Idol-not real. Fear Factor- not real. I mean seriously people, I get offered money all the time to eat rocky mountain oysters.
Those are all glorified game shows. Just because someone breaks down in front of a camera while trying to win something doesnt make it reality, in fact all of that crap is far from reality.
Now REAL reality TV, awesome! Cops, The First 48, Intervention, Dog, local evening news, all great shows.
