The viewers then vote to decide who will be Evicted. The last person left wins the major cash prize. Big Brother is the original and unparalleled social experiment. For the most part, the Housemates are left to do as they please in a hyper-real environment largely unpenetrated by the outside world while everything they do is watched by cameras - and ultimately the public. Tasks constitute the only real interference with the Housemates' lives. Basic food and shopping money is provided for staples, however the Housemates have the opportunity of increasing their weekly allowance, or furthering their position in the game, by passing these Tasks. The action unfolds in real time. Everyday living combines with friendship, arguments, love, betrayal and despair to become the stuff of a real-life soap opera.
