Given the numbers of viewers they were quoting for the game, this is an opportunity lost by the FFA to actually convert some into either members of the Jets or at least crowd members at some games. I'd suspect the flow on effects would have been similar for the NPL.
I can't see how broadcasting a game that FOX couldn't give two tosses about would hurt the FFA or FOX. I can see how it may build an additional client base, but they went and ****ed that.
