If you are addicted to Shark Tank and have seen em all, it's based on a Canadian (and even earlier british) show called Dragons Den. I admit going back after watching Shark Tank it will seem a little hokey and they let a lot of goofballs on there with brutal ideas, but its about half of the same sharks (they were called dragons) and there is 5+ seasons. Same show just smaller scale.
I watch both of these shows every week, shArk tank is entertaing and some people with good ideas on there, I really like the profit Marcus seems to be a very good bussiness man ,I love when he puts his spin on the bussiness'
