Big Brother
originally aired on CBS
The American series launched on July 5, 2000 on CBS, and since the discontinuation of the Spanish version in 2022, is the longest-running adaptation in the Big Brother franchise. The show broadly follows the premise of other versions, in which a group of contestants live together in a specially constructed house that is isolated from the outside world for a cash prize of $500,000. The success of the series has spawned several spin-offs, Big Brother: Over the Top, Celebrity Big Brother and Big Brother Reindeer Games, which aired for one season on CBS in December 2023.
