I just re-read Alex's interview on here about this season. Sounds like he has already gone back on what he said:
In the most recent season of Big Brother UK, there was a constant stream of outside information fed to the housemates as well as much contact with the outside world. This really flies in the face of the number one premise of Big Brother. Can you give us an undertaking that you won’t make the same mistakes as they did? (timmydownawell)
Chris and myself are Big Brother purists – the show is in our DNA and we are dead against too much contact from the outside world.
Yes, there are always exceptions for big hit stunts towards the end of the series – I’m talking about things like friends and family nominations and the Freeze task – but even then, there is limited contact.
This year, the audience will have a bigger say in the house – this could mean we will allow housemates to read a tweet as a reward or something (obviously heavily moderated by Big Brother) and that is just a natural evolution of the format.
But yes, you have an undertaking that our house will never become a revolving door of guests and that our housemates will receive very limited information from the outside world. We wouldn’t have it any other way.
