response: I'm not sure, but the limbs of the bow are much stiffer than for a recurve or longbow.
original_response: I'm not sure the exact time, but it didn't start seeing common use until more modern manufacturing took off in America.
history: Archery is a really fun sport. Oh, is that so? I know of it as using a bow to shoot an arrow. Interesting.  When was archery first used? I have no idea, but it historically has been used for combat and for hunting. I really enjoy the long bow.  Do you know when it was created? I don't, but I know the bow and arrow in general were invented either in the late Paleolithic period or the early Mesolithic. Wow, and it's still relevant today.  When was the first compound bow created?
knowledge: The pulley/cam system grants the user a mechanical advantage, and so the limbs of a compound bow are much stiffer than those of a recurve bow or longbow.
