The show followed a total of twenty-two contestants, known as housemates, who were isolated from the outside world for an extended period of time in a custom built house.

The last remaining housemate, Pete Bennett, was declared the winner, winning a cash prize of £100,000.

Big Brother 7 was the subject of viewer complaints and press attention regarding a variety of controversial issues, including the wellbeing of certain participants and the decision to allow former housemates to re-enter.

The title sequence contained phrases such as, at the very beginning with a screen resembling an FBI Anti-Piracy Warning: "This is the title sequence for Big Brother", "In agreeing to take part in Big Brother you agree to abide by the rules.

On Day 23, Susie entered the House as Big Brother's lucky Golden Ticket winner.

Housemate numbers also topped series 6, in which even after the "Secret Garden" twist, there were only a total of sixteen contestants.

Members of the public finding these tickets were permitted to use them to give themselves a chance to become a Big Brother housemate and bypass the standard auditions process.

Golden ticket holders were invited to a television show where one of them, Susie Verrico, was chosen to enter the House by housemate Aisleyne picking a ball out of a machine at random.

Big Brother deemed this a form of 'code' and issued a warning to Glyn, who retorted "But Welsh is a British language".
