R.E `s idea about the small box in the screen is about right ,but it might work better the other way round.Think about it we sit for the best part of three hours making our eye sight bad ,if we had abig box for the ad`s and a small box for the race i`d have to get of my rear to go right up close to the tv to see, this way i`d get a bit of movement going in the old joints and not feel so tired after the race.Or put three hours of adverts on ITV4 while the race is on thats got to be better than The planets funniest animals 17 or ,When stunts with your pets go wrong 12.
