In 1891 James Naismith, a Canadian immigrant to the United States of America, was asked to invent an energetic indoor game for high-spirited young men. He came up with basketball, which so captivated his female colleagues that they began playing too. Within a short time, Naismith's rules were misinterpreted by a sports teacher in New Orleans, USA, and netball was born. The all-women sport quickly spread to England and the British Commonwealth. The International Federation of Netball Associations (IFNA) estimates that there are in excess of 20 million women playing netball in some 80 countries around the world.
