Several people have raised the notion of corporatization and homoginization of the sport. I think this is a very valid point, but it ignores both the mission of the PDGA and the goals of the manufacturers. Good or bad, the mission of the PDGA is to grow the sport through professionalization. The manufactures want to grow for the obvious reasons. Keeping disc golf small and comfortable isn't a bad thing, it just ignores what is happening. You can work towards countering that, but you aren't likely to succeed long term. That said, I worry less about this than some. Disc golf won't support the kind of coverage and attention that other big sports do. The money isn't there, it's too cheap to play, and you can't fit enough players into a tournament to compensate by volume. That doesn't mean there isn't room for growth. If you take hiking as an example, there is no way to get it on television, but it is a multi-billion dollar participation sport that is marketed and managed like any business. Speaking of clothing, how many people wear hiking shoes and hiking clothing day to day? Lots do, for no real functional purpose than they think it makes them look cool.
IMO you're never going to build disc golf like a major sport, its structure limits that growth. But if you grew it's popularity similarly to something like X games, you could have non participant wanna be watchers. I love watching X games, no way am I doing that. Our model seems to be one of growth through participation. Again, I think that is severally limited. Even trying to get people to watch straight up is a tough sell. Getting people to watch because it's cool to watch is a different tactic, and IMO, a better option.
