Big Brother

Big Brother is a television reality game show based on an originally Dutch TV series of the same name created by producer John de Mol in 1997. The series follows a diverse group of contestants, known as HouseGuests, who are living together in a custom-built home under constant surveillance. The HouseGuests are completely isolated from the outside world and can have no communication with those not in the house. The contestants are competing for a $500,000 grand prize, with weekly competitions and evictions determining who will win the show. The series takes its name from the character in George Orwell's novel Nineteen Eighty-Four. The series launched on July 5, 2000 to a successful start, though ratings and critical reaction continued to grow increasingly negative. This led to the second season being a revamp of the show, featuring a more competition-based challenge. The series has since continued to be a hit for CBS, and is the second longest-running adaptation of the series to date, after the Spanish adaptation.

The series currently has two spin-offs: Big Brother: Over the Top, which was the first reality game show to air exclusively on a streaming platform airing in Fall 2016 on CBS's streaming service, CBS All Access; and Celebrity Big Brother, which aired on CBS in February 2018.

CBS also renewed the series for a 19th and 20th season. The 19th season premiered on June 28, 2017, while the 20th season is expected to premiere on June 27, 2018.
