Big Brother 2007, also known as Big Brother 8, was the eighth series of the British reality television series "Big Brother". The show followed twenty-three contestants, known as housemates, who were isolated from the outside world for an extended period of time in a custom built House. Each week, one or more of the housemates were eliminated from the competition and left the House. The last remaining housemate, Brian Belo, was declared the winner, winning a cash prize of £100,000 (the second housemate to do so after Liam McGough was awarded the same amount in the third week).
