Just a little thought I had last night. TiVos can be programmed to record whole series at their owner’s request, so how about if they could block particular programmes as well. For instance, if I flipped onto Channel 4 or E4 whilst Big Brother was on, I’d like the sound to go off and the screen to go blank apart from a message along the lines of “Move along. Nothing to see here.”

Of course, the urge would be to go a bit mad. ITV would be permanantly blank, all football would be removed and there’d be a moving black box sat atop Ricky Gervais.
