A 30 minute time slot after adverts are removed only leaves 24 minutes of programming. Little wonder selective editing is a huge problem which distorts events and indeed encourages unneeded cencorship.
I have never understood why BB is allocated such a short daily time slot on mainstream tV. Most of the gaming and interaction that occures late into the evening never gets broadcast. A typical example was the night before Sandy left when they were up till after 5am.
