no one really does... i almost started a disc golf timeline outlining the big break-throughs. if i remember, there was a DGWN or disc golf journal that had an "important disc events in development" thing that had like the top 10 most important design evolutions.
if you have any specific requests, i can pretty much be accurate within 1-2 years on just about everything.
e.g. original eagle/aero 1993, first aviar proto 1985, p-38(#2 hookshot) 1987, bead invented 1988 (cobra), first roc 1988, viper 1990, cyclone 1993, gazelle 1995, xl 1998, etc.
