Honestly I don't think the money men would care. The ITV bods don't seem to care that England home games routinely have about half an hour of each match (first fifteen minutes of each half) with tons of empty seats visible right in front of the camera because the fat ****s in the Club England section are too busy devouring their pureed aubergine and pancetta soup or whatever the fuck they get as part of their package. If Sky actually cared about sparse crowds affecting the TV viewer's experience, they would just push the clubs to make sure the visible sections were always full even if it meant closing off the parts of the ground that aren't on camera. Or they could give tickets out for free. Dishing out a few thousand free tickets would be small change compared to the money they would make by ensuring tens of millions of foreign fans are watching on TV.
