Wat actually is a Big Brother show?

it's a show wherein a group of strangers (around 12 or more) will reside on 1 house for 100 days. they are not allowed to go out. they don't know anything about the outside world..imagine for 100 days!!?they have to deal with themselves and their daily task given by the BIG brother. rivalry, relationships,and friendship usually happen on thsi kind of situation. weekly, they have to vote for a housemate to go out. and the one who will remain will win the prize!

I do not think that I have heard of this Big Brother show that you are talking about. I will have to look it up.
