Set up in the US in 2001, Creative Commons’ first copyright licences were released the following year. With the licences came a web application platform that helped users with the copyrighting process. In 2003 there were about 1 million Creative Commons licences in use, and the number grew exponentially. The chart shown here lists the different Creative Commons licences according to whether or not they require attribution, allow use of a work to make money, or permit a work to be changed. So, for example, Te Ara – The Encyclopedia of New Zealand allows use of text and some images under the Creative Commons Attribution-NonCommercial 3.0 New Zealand licence.
