Creative Commons has published an infographic, called State of the Commons, illustrating the extent of CC licensing in 2014. According to them, the number of Creative Commons licensed works is approaching one billion. The most common license in use is Creative Commons Attribution-Share Alike, the one I’ve used for Green Comet. CC-BY-SA is the third most open license, and the least open to still be called a Free Culture license.
This is encouraging news.. I’m glad to be part of it.
