The 'fill in' you are noticing on BBC programs,is why things like 'Planet
Earth', have a ten minute 'making of' bit at the end. Programmes are being
made on the assumption that they _will_ be shown at some point on a
channel with advertisements, so 'full' timing, is being avoided, and they
aim for about 50 minutes in the nominal hour.


If they aim for 50 minutes in the hour there will still be 10 minutes cut
from it. Timings I did recently showed that the average "hour-long"
programme only runs for 40-41 minutes. The rest is made up from normal
adverts, adverts for the station, and those annoying Dave Bedford
impersonators topping and tailing each segment.
