Big Brother 2005, also known as Big Brother 6, was the sixth series of the British reality television series Big Brother. The show followed sixteen contestants, known as housemates, who were isolated from the outside world for an extended period in a custom-built House. One or more housemates were evicted by a public vote each week. The last remaining housemate, Anthony Hutton, was declared the winner, winning a cash prize of £50,000. Runner-up Eugene Sully also won the same amount during a task two days before the final.
