The reason for the bit at the end is that these programs are sold world wide so they only run for 45 to 50 minutes or so to fit in the advert breaks. The extra at the end is for the UK where, thankfully, we dont have advertising on the BBC just yet.
So, please stop whining and just accept thats how things are and if the BBC disappears altogether, Dave will be a perfect example of how ALL broadcast television will end up if it hasnt already done so: 10 minutes of content with 20 minutes of adverts per hour.
