[Bigbrotherin]

I think big brother is a brand that as long as you have a good set of housemates each year, will never really reach a natural end. It's been comissioned for another 3 series excluding this year and it will continue for at least those 3 years IMO. Infact if Big Brother changed an aspect of the show each year and kept it fresh, Big Brother could go on for another 5 to 6 years easily.
