How rugby balls have changed over time
After colleges began to organize sporting competitions, uniform rules were required and sports became more defined. Rugby and football were very both similar originally, and largely considered the same sport. Both received official rules, splitting the sports into rugby football - commonly known as rugby - and association football - known as football in most of the world, or soccer in the US. As the sports began to grow, the balls themselves changed with the times. Initially, the rugby ball was hand stitched and was made from leather with a pig’s bladder inner tube. Today, we’re more used to the traditional oval shape of the rugby ball, and they’re now made of stronger materials designed for the pitch, mud and rain.
