Celebrity Big Brother is a British television reality game show based on the Dutch show Big Brother, created by producer John de Mol in 1997,[1] which aired from 2001 to 2018, and again since 2024. The show follows a number of celebrity contestants, known as housemates, who were isolated from the outside world for an extended period of time in a custom built house. Each week, one of the housemates is evicted by a public vote, with the last housemate named the winner.
