What international test football does is put corporate interest into the sport, which tend to be blue chip business.
The global exposure is what attract these companies.
Test football represents a nation and therefore appeals to the masses who perhaps wouldn't normally give a shiny shat at club level.
Test football is the real growth area that union have grasped and League for perhaps the last 50 years have squandered.
I think this new guy from the FA at the RFL may have been instrumental force in lifting the profile of league internationally.
Tees or Yed? (sorry don't know which) said the other day that England RU is the only national team he doesn't support, I would hazard a safe bet because of the jealousy we have over the success international RU has and the bitterness we feel from our impression of the way RFU always seems to belittle League.
I think many of us share some of that reasoning for being anti England RU.
Putting that above reason for not watching RU aside I think if any of us had the opportunity to watch an international, we would and that is the whole point.
The game in London will certainly be the highest attended of the trio and I would guess the biggest part of that crowd won't be from the heartlands too.
For a player there is no other higher honour in the game than representative football.
