The discussion of video attracting people to the sport is any interesting one. I just took a four year hiatus from the sport, kids, who know they took so much time, and having started playing again have noticed a very large change that has occurred. The number of people who want to be seen as knowing the sport, or knowing about the sport has increased exponentially. I'm not talking about guys playing, simply people in the street. The number of people, young and old, who comment on my gear is significant. Four years ago, very few noticed, now, pretty much every time I have something marked disc golf, someone asks or comments. Most typically, I get an, "oh yeah, I've played," comment. Especially with younger kids, high school and under. Some of it is true, a lot of summer camps in the South have added courses, for all the obvious reasons: cost, in the woods play, even out of shape kids can participate, easy to play, etc.
Whether that ties to video or not I don't know. The PDGA can make an argument that their EDGE program and their marketing has paid off, and I'd add in that the whole spread the game concept has probably had a bigger impact, that is, players wanting to spread the game would be more effective in my opinion.
The number of new warm bodies playing is huge; in the 10 years I played before taking a break, I knew most of the local players and the in and out movement wasn't that big. Also, the number of clear newbies is huge, based on what I see on the courses, relatively speaking. Clearly a sea change has happened, at least in Houston, and I wouldn't be surprised to hear it is a national trend.
