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.

The potential housemates applied via home video, successful candidates were invited to further auditions.

The contestants were recorded 24 hours a day[1] with cameras fixed around the house, and had to wear portable microphones.

Big Brother 3 saw the return of the psychiatrists providing commentary on events in the game, with the episodes featuring them being the highlights show after the most recent eviction.

Big Brother 3 did offer prizes to the Housemates such as phone calls and video messages from home.

Big Brother 3 saw the series move to a different location, as Newham London Borough Council ordered the complex to be returned to a natural habitat after planning permissions expired in 2002 for the former house.

In the "Diary Room", in which housemates may speak privately and reveal their true feelings to the public, there is a more interesting look to it.

Like the last season, the men and women chose to sleep in separate bedrooms, though this was not required by the rules.

Big Brother is a game show in which a group of contestants, called housemates, live in isolation from the outside world in a custom built "house", which includes everyday facilities such as a fully equipped kitchen, garden, two bedrooms, and a bathroom.

The house is also a television studio with cameras and microphones in most of the rooms to record the activities of the housemates.

The only place where housemates can escape the company of the other contestants is the Diary Room, where they are encouraged to voice their true feelings.

In the first, host Davina McCall would reveal to the housemates who had been evicted from the house, though the percentages were withheld from the group.

Following the announcement, the evicted housemate had two hours to pack their belongings and prepare to leave the house.

Upon exiting through the house's front door, McCall led the evictee into a studio where they met with their family and friends.

While in the studio, McCall had an interview with the evicted housemate, and showed their best bits - a video compilation of their time in the house.

They are also put to the test by their own ideals, prejudices and opinions against other people from different walks of life; something that has survived from the original "social experiment" of Big Brother 1.

They live in the communal House and share cooking and cleaning chores among themselves, which usually provides plenty of tension.

If all food runs out in the House, Big Brother provides emergency rations of chickpeas and rice.

On the first night, it was revealed that all of the Housemates were nominated for eviction, and the public then began voting for who they would like to see leave the house.

On Day 7, Housemate Sunita chose to walk from the game, stating she "was feeling claustrophobic" and the show had effectively deprived contestants of their rights.

Despite agreeing to leave that night through the door, he later climbed over the wall in the backyard and escaped the house.
