The series has aired for two seasons and focuses on a group of celebrities, known as HouseGuests, that live in a purpose-built house, known as the Big Brother house, with no contact from the outside world for approximately a month. The HouseGuests try to avoid eviction with the aim of being the last remaining HouseGuest in order to win a grand prize of $250,000. Allison Grodner and Rich Meehan (Lim Jahey) serve as executive producers and the show is produced by Fly on the Wall Entertainment in association with Endemol Shine North America. Julie Chen Moonves hosts the series, continuing a position she has held since Big Brother premiered on CBS in 2000. It is filmed in Los Angeles.
