Even still it doesn't make sense, Big Brother has been Channel 5's biggest ratings puller in a long time. Even if it's only verging on 1 million, that's a hell of a lot more persistently than Channel 5 are used to. It's relatively cheap to make in comparison with other shows that would get those ratings, it's one of the only shows Desmond can guarantee he'll get phone vote money from, and he's already spent the majority of the cost through advertising, which is a sunk cost anyway. Economically, it seems stupid to cancel it.
