The WFDF has 62 member associations and covers 58 countries. The pastime (sport?) has variations but Ultimate Frisbee is seen as the godfather of the disciplines.
"It's just a great sort of blessing of credibility for the sport," Tom Crawford, chief executive of USA Ultimate, the national governing body (honestly, you can't make this up) for flying disc sports, said. "It's a legitimate sport and not just a game you play in your backyard."
The game is played on a rectangular field 64m by 37m with 18m deep end zones.
Throws are called pulls and each time the attacking team completes a pass in the defending team's end zone they get a point.
Players can't run with the disc and have 10 seconds to make a throw, and that's about all you need to know.
A few years ago ballroom dancing was being considered for an Olympic future. Seriously. Now, far be it to suggest ballroom dancing is not an athletic pursuit.
Indeed, a high degree of physicality goes into it, more so, you can argue, than, say, shooting, which is an Olympic staple. Shooting's key is mental durability. All this raised the thought of what the summer Games might look like in 20 years time.
Cast the mind back and consider some of those sports which were on the programme but have sunk without trace. Tug-of-war had a run of six straight Games until 1920. At the London Games of 1908, the Guardian newspaper devoted an entire column to the sport, with the headline: "Sports that foreigners excel in".
In Paris, in 1900, the 200m swimming obstacle race took place, in which contestants had to climb over a pole hovering just above the water, scramble over a line of parked boats then swim under another row of them.
There was an equestrian long jump, won with a 20-foot leap by a spectacularly named Belgian, Constant van Langhendonck (the rider not the horse).
Further grist to the argument that Paris must have been a belting Games - croquet, hot air ballooning - there was the live pigeon shoot.
Another Belgian, Leon de Lunden, took the cash prize (!!) of 2000 francs for murdering 21 birds. Not surprisingly, it was quickly dropped.
In the Los Angeles Games of 1932, club swinging was a Games sport. It involved men in tights tossing wooden clubs about in nifty patterns. True.
Enough of that. Eight sports are on the shortlist for inclusion to the Tokyo Olympics in 2020. All made a presentation to Tokyo bosses yesterday.
There's an old argument that a sport must be rejected, even repeatedly, before getting a nod from an organising committee. The eight in contention this time are baseball and softball, bowling, karate, roller sports, sport climbing, squash, surfing and wushu. As there's already two martial arts (judo and taekwondo) on the programme, that drops karate and wushu down the list. Baseball and softball is tipped to make it, plus one more when the final decision is made by the IOC next August.
What's worth remembering is that the IOC is conscious of making the Games a more relevant event, which could place the likes of fencing, archery and modern pentathlon vulnerable and makes young people's sports pursuits (cue frisbee) viable in IOC minds, in time.
There are moves to trim events within sports, notably the biggies, athletics and swimming.
So while all bar frisbee disciples might hoot at the prospect, time does not stand still. If the sport comes to be seen as a good fit for a modern age, they could be having the last laugh.
