Bowling is a sport in which players attempt to score points by rolling a bowling ball along a flat surface, usually a wooden or synthetic surface, either into objects called pins or to get close to a target ball. There are many forms of bowling, with one of the most recent being ten-pin bowling. Primitive forms of bowling may have existed in ancient times as early as A.D. 300 in Germany, and also in ancient Finland and Yemen. The first standardized rules were established in New York City, on September 9, 1895. Today, bowling is enjoyed by 95 million people in more than ninety countries worldwide and continues to grow through entertainment mediums such as video games for home consoles and hand held devices.
