Big Brother 6 is the sixth season of the American reality television series Big Brother. It is based upon the Dutch series of the same name, which gained notoriety in 1999 and 2000. The series premiered on CBS on July 7, 2005, and lasted eleven weeks until the live finale on September 20, 2005. This season was the second to be accompanied by the House Calls: The Big Brother Talk Show spin-off series, which was viewable online and discussed the events of the game. The sixth season saw a moderate decline in ratings. The season premiered to a total of 8.47 million viewers, the lowest premiere numbers since 2001. Though the finale had a total of ten million viewers, the series averaged 7.24 million viewers, a series low at the time. Big Brother 6 featured a total of 14 HouseGuests, the same number that was featured in the previous season. This was the highest number of initial HouseGuests to enter the house, due to the twin twist the previous season. The series ended after 80 days, in which HouseGuest Maggie Ausburn was crowned the Winner, and Ivette Corredero the Runner-Up.
