 There have been twenty completed seasons as of 2020, sixteen regular seasons and four celebrity seasons.Based on the original Dutch version created by Endemol, the show sees a number of "housemates", divided by gender, social backgrounds and geographical locations, locked up together in a house, where the viewing public can watch them twenty-four hours a day, and vote them out of the house as they choose.The housemates can visit the "confessional" at any time during the day, either to talk to psychologists if they need to, talk to "Big Brother", or to nominate.
