CC stats
My iSummit presentation on Creative Commons license adoption and related statistics can be found along with Mike Linksvayer’s slides on the Creative Commons blog, but you can also access it here: iSummit presentation.Main findings:
- There are at least 40-60 million CC-licensed items online
- About 2/3 of the content are licensed under NC
- SA and ND are also popular attributes, although ND is popular only in combination with NC
- BY-ND is by far the least popular license
- 80% of the content is licensed under the generic-unported CC license
- The use of ported licenses exhibits significant variations between jurisdictions
- The Spanish license is the most popular, probably because of high awareness of the licenses in Spain as well as the fact that the licenses are used by many South American users
- The Swedish, Bulgarian, and Israeli licenses appear to be used in the most liberal way (i.e., users in these jurisdictions tend to share more liberally)
More to come on CC stats in the near future…
