You can come up with reasons why the AFL is more established in it's non-heartland areas but that not what I'm arguing I'm just stating it is. But you fall back to ratings which appears to be the only statistical anomally when comparing the although I concede it's a big one. It would be the same as an aussie rules fan pointing to just crowds, membership, participation or revenue and saying it's twice as big.The AFL is more established in its non-heartland states than the NRL is in theirs, but considering the time and resources the AFL has committed to those areas, so it should be, and really the difference should be a lot greater than it is, particularly when looking at ratings.
The NRL doesn't rate 'close' to the AFL, both codes rate pretty much neck and neck. The length of the two games would obviously come into it when ratings are averaged over the length of the program, but that doesn't negate the ratings of the NRL. The game rates well because people watch it, people watch it because it's popular, trying to come up with excuses for why their ratings are wrong because it doesn't fit a prejudiced belief or judgement that it couldn't possibly rate as well as AFL, is arrogant, and for the purposes of this thread, pointless.
I'm just putting my 2 bobs worth in why I think The NRL punch above it's weight with TV ratings or perhaps it the AFL punching below it's weight.
