List of Big Brother American TV series episodes 20002009

Big Brother is an American reality TV series based on a Dutch original created by John de Mol Jr., which debuted on July 5, 2000. Contestants, known as HouseGuests, live in a custom-built home under constant surveillance and isolated from the outside world. The first season featured weekly nominations and public votes to eliminate two contestants, with the public deciding who stays. However, declining ratings led to changes in Season 2, introducing a competition-based format where HouseGuests compete for power and safety, voting to evict one member each week until two remain. In the finale, previous HouseGuests vote for the winner, receiving the grand prize. As of September 19, 2024, 936 episodes have aired, concluding the twenty-sixth season, with casting underway for Season 27.
