Personally, I watch very little on "normal" TV. Pretty much everything I watch that is not sport is watched on-demand through Virgin, or 4od on t'interwibble. This is basically because "primetime" seems to mean the time of the day when those with a life are not watching TV. Occasionally, the Weakest Link goes on when I get home from work, but that's just to make myself feel clever if I've had a rough day!

I really appreciate the lack of adverts in most on-demand stuff. Personally, I beleive that if you have to pay a subscription for a channel, they should not be allowed to advertise.
