(Warning: this is unofficial data, please take it with a pinch of salt). Some few days ago the Creative Commons blog reported that there were 53 million pages linking to Creative Commons licences. It seems only yesterday that we were amazed by the fact that there were 16 million pages. I have checked the unofficial figures and there are now 54 million link-backs to Creative Commons!
What can account for such a meteoric rise? I think that blogs and sites like Flikr are largely responsible for a large number of links, but it would be difficult to know for sure without raw data about domains. Still, the data is a good indication of the mainstream online acceptance of CC as a viable movement.
Some other interesting figures. Most links are for the “Generic” licences, although the jurisdiction specific are rapidly gaining ground. Unsurprisingly, the most popular jurisdiction licence are the non-English ones: Spain, Germany, France and Italy, although the England and Wales licence has now surpassed the 80 thousand licences. It also seems like most people prefer the Attribution-NonCommercial-ShareAlike licences, with 35%. Here is a graph describing the licence breakdown:
