"This would not create new fans."
I first learned about this sport via a random google search. Two of my friends also found out this sport even existed via the internet. We are not the only ones interested in sports that from time to time use google or facebook. There are millions and millions of people that you can reach without spending a dollar that way. If things improve, more than us 3 will follow, and hopefully for the US frontons not only in scandinavia but in the US too.
You will never discover things that are not there to discover. The frontons need to be more visible.
