Pool evolved from a lawn game similar to croquet played sometime during the 15th century in Northern Europe.

Pool is one of the safest sports in the world.

Before the invention of celluloid and other new-age plastics, billiard balls were made out of ivory.

Billiards was the first sport to have a world championship (1873).

The first plastic was used to make billiard balls. The material was used by Isaiah and John Wesley Hyatt to enter into a contest to find a new material for billiard balls.
