The International Organization for Standardization was founded in 1947 to promote the exchange of goods and services throughout the world. Comprised of member organizations from 140 nations, the international group sets standards for everything, from the size of credit cards, to the representation of country names. The organization is also known as the ISO, which is a play on words. It is not the acronym for the group; it is based on the Greek word isos, meaning "equal."
