Big Brother is a Canadian reality television show. The show follows a group of people known as "HouseGuests". They are not allowed to contact anyone from outside the "Big Brother" house. They are under constant surveillance of cameras and microphones. They live in the house for a chance to win $100,000. Each week the HouseGuests will vote to evict one of the two nominees from the house until two remain. The winner is decided by the last seven evicted HouseGuests, known as the "Big Brother" Jury.
