Big Brother is a reality game show franchise created by John de Mol. The premise of the show is that a group of people live together in a large house, isolated from the outside world. They are continuously watched by television cameras. Each series lasts for around three months, with 12–16 contestants entering the house. In order to win the final cash prize, all the contestants have to do is survive periodic evictions and be the last one standing.
The idea for Big Brother is said to have come during a brainstorm session at the Dutch-based international television production firm Endemol, on March 10, 1997. The first-ever version of Big Brother was broadcast in 1999 on Veronica in the Netherlands. Since then the format has become a worldwide TV franchise, airing in many countries in varying adaptations.
