What has Big Brother taught us about human nature?
The last Big Brother housemates have entered the house as the show begins its final series in the UK. What has the show taught as about society?
The series, which is popular around the world, has seen its fair share of arguments over the years. In one US series, broadcast in 2001, a housemate was expelled from the show after threatening another with a knife.
In 2004, UK viewers complained following a violent drunken fight between two housemates and in 2007, the Australian version of the show was criticised for deciding not to tell a contestant that her father had died.
The UK celebrity version of the series has also seen its share of controversy, with the a heated race row involving Jade Goody and Bollywood star Shilpa Shetty in 2007.
Are you a fan of Big Brother? Do you think the series is a true reflection of society? Has the programme taught you anything about human nature? What have you learnt from the show?
Big Brother began on Channel 4 on Wednesday at 2100 BST.
