Michelle Thorne, of Creative Commons, has an analysis of the 100 Million Creative Commons Photos on Flickr (covered yesterday by OEN). Thorne notes that the most common license is BY-NC-SA. She also notes the variable growth rate of CC-licensed photos on Flickr over time. From the article:
Also very surprising is the growth rate of the number of CC-licensed photos. The monthly growth rate sunk from an initial 13% (April 2006) to about 4% (November 2008), at which point growth more or less stabilized. Presently, the pool of free images is increasing about 4% in comparison with the previous month. That means that the absolute number of monthly gain in photos is rising.
