Big Brother 2002, also known as Big Brother 3, was the third series of the British reality television series Big Brother. The show followed fourteen 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 evicted by a public vote. The last remaining housemate, Kate Lawler, was declared the winner, winning a cash prize of £70,000.
