Yep, I have to agree, being from Canada, tennis is on the rise for youth. Yes, this has a lot to do with the past 10 years (having some Canadian tennis stars), but many more parents shy away from hockey then in the past due to head injuries.
I grew up playing hockey my whole life and most everyone I knew did too. However, myself and several of my friends have already said they won't let their children play it seriously. It's insanely expensive as well, even in Northern Quebec.
However, if FAA and Shapo can start winning slams, I think tennis will boom here, it is ready for it. I think this is the case for many countries, even the US. Imagine 2 or more Americans in the top 10 winning slams? It would bring popularity back.
I am sure Murray did that for the UK, and others for their countries as well, but America is a huge market.
