A group of contestants move into the Big Brother house, where they nominate each other to be evicted by public vote. The last person remaining will take home a large cash prize, while the others take home nothing.

Big Brother takes place entirely within the confines of the Big Brother House, where the object is to be the last remaining housemate. At least one housemate will leave the house every week by a process of nomination and public eviction. Housemates will nominate each other for eviction, and those with the most votes from their peers face a public vote. The housemate that receives most public votes leaves the house and is out of the competition. Housemates are provided with a shopping budget each week to buy food and other necessities. Throughout the series, housemates will be asked to complete tasks set by Big Brother; if the group does well in the tasks, they are rewarded with a bigger shopping budget, plus special treats. On the final night, the public will vote on which housemate they want to win the show. The housemate with most votes wins a large cash prize.—Anonymous

A number of contestants live in an isolated house trying to avoid being evicted by the public with the aim of winning a large cash prize at the end of the run. It is based on the Big Brother series produced by Endemol. The show's name comes from George Orwell's 1949 novel Nineteen Eighty-Four, a dystopia in which Big Brother is the all-seeing leader.—Bigbrotherfan
