The Eagle, which was quickly re-tooled into the Aero landed in the Spring of 1983 (although the list below indicates an earlier date of approval). At that time, it was just a disc; there were no putters, mids, or drivers. It wasn't too long before this disc, that would someday be called a "putter," set a new distance record in the 500's. The Aviar came after the Aero, and then then the Aviar XD (extra distance). Below I've listed all Innova Discs that have been approved by the PDGA. The first disc that we can now call strictly a driver was the Phenix. It was tooled using the Aero mold, and the Aero went away for several years before its return as a "putter." The Phenix, thrown by Sam Ferrans, set a world record as well. Subsequent "drivers only" were the larger-diameter Barracuda and Scorpion, followed by the even-bigger Jaguar. The Viper with a 21.7 cm diameter was the first driver that was the same size as the existing midranges as the Shark, Stingray, Roc, Cobra. It wasn't until 1992 and the Whippet that a smaller (21.2) diameter driver showed up. Since then, most drivers have been close to this size. I think it was in the first half of the 90s that companies started designating discs as drivers, midranges, and putters.

Were they considered putters back then? Or just discs?
