Creative Commons metrics
Creative Commons has collected metrics on works licensed under Creative Commons since 2002 by searching for references to licenses on the web and tracking links to the Creative Commons website. The metrics provide some insights but are limited by variations in search engine algorithms and indexes over time. New pools of Creative Commons licensed content like Flickr and Jamendo saw growth that may have been linear at first but could become exponential as these types of content platforms grow.
