I would have to consult "the Frisbee book" to be sure, but in the 1970's there was a big push to turn every sport into a Frisbee (disc) sport. I believe Ultimate is what became of Frisbee Football, much like Disc Golf evolved from Frisbee Golf. Freesyle was the big disc sport back then. Disc golf and Ultimate became the most popular of these disc sports eventualy though. Ultimate is a team sport that caught fire with colleges and to my recolection is not played recreationaly as disc golf is.
