Big Brother (U.S.)

''This article is about the English Version in the United States. For the Spanish Version, see Gran Hermano USA.''

Big Brother is a popular international reality show franchise with an American version owned by CBS.

How it Works
Big Brother is a reality television show in which a group of people live together in a large house, isolated from the outside world but continuously watched by television cameras. Each series lasts for around three months, and there are 10-17 participants. The housemates try to win a cash prize by avoiding periodic evictions from the house.

American series
While most versions of Big Brother feature evictions that are voted on by polling television audiences over the phone or the internet, the American version shifted before Big Brother 2 to play off the popularity of Survivor and changed the format to have the other house guests evict players.

BIG BROTHER follows a group of people living together in a house outfitted with dozens of high-definition cameras and microphones recording their every move, 24 hours a day. Each week, the houseguests will vote someone out of the house. At the end, the last remaining houseguest will receive the grand prize of $500,000.

History
The idea for the show is said to come during a brainstorm session at the production house of John de Mol Produkties (an independent part of Endemol) on 4 September 1997. The first Big Brother broadcast was in the Netherlands in 1999 on the Veronica TV channel. It was picked up by Germany, Portugal, USA, UK, Spain, Belgium, Sweden, Switzerland and Italy the following year and became a worldwide sensation. Since then it has been a prime-time hit in almost 70 countries. The show's name comes from George Orwell's 1948 dystopian novel Nineteen Eighty-Four.

As of Big Brother 21 (US), a total of 307 people have participated across 22 main broadcast seasons (272 players), one digital season (12 new players), and two celebrity seasons (23 players). As of Big Brother 22 (US), 40 players from the main broadcast seasons returned to play the game again, including one who crossed over to the digital season. Of those 40 players, six of them returned to play for a third time, while one of those six then went on to play the game for a fourth time. That marks 47 times those 40 players returned overall.

Nine other players were eligible to play the game again but ultimately did not make it in again, either due to losing a fan vote, or in the case of Big Brother 11 (US), having their Clique lose the opening challenge. One player had two chances to play again but failed to enter both times. In Big Brother 1 (US), one woman was given the chance to enter the game late but ultimately did not enter.

Two contestants are connected to Celebrity Big Brother (UK), with one who originated on Big Brother 16 (US) crossing over to Celebrity Big Brother 18 (UK), while one who originated on Celebrity Big Brother 20 (UK) crossed over to Celebrity Big Brother 1 (US). Another contestant was eligible to participate in Big Brother Canada 4, but did not get voted in.

Usually the contestants are all strangers who are meeting each other for the first time when they move in, but in some seasons, twists have been implemented where at least two contestants know each other before entering the house, whether through a friendship, current or past relationship, or a familial connection. Not counting Returning Players or celebrity contestants, houseguests who have a pre-existing relationship hail from the following seasons: Big Brother 4 (US) through Big Brother 9 (US), Big Brother 17 (US), Big Brother: Over The Top and Big Brother 21 (US).
