Im looking at the tv guide and there is nothing that rivals big brother on any major channel. Channel4 have been very clever.
BBC1 - Calendar Girls: 10 years on

BBC2 - A World of pain: Meera Syal on self-harm

ITV1 - Taggart

Channel 4 - Big Brother Launch Show

Five - The Mentalist
Sky1 - Bones
BBC3 - How to rob a bank
I honestly think Big Brother may get the highest launch figures in the last few years, as nothing rivals the launch. This might also pull in new viewers
