 "Big Brother" is a game show in which a group of contestants, called housemates, live in isolation from the outside world in a custom built "house", which includes everyday facilities such as a fully equipped kitchen, garden, two bedrooms, and a bathroom.The house is also a television studio with cameras and microphones in most of the rooms to record the activities of the housemates.The only place where housemates can escape the company of the other contestants is the Diary Room, where they are encouraged to voice their true feelings.
