The Creative Commons has released State of the Commons.
Here's an excerpt from the announcement:
Today, we're releasing a new report that we think you will want to see. State of the Commons covers the impact and success of free and open content worldwide, and it contains the most revealing account we've ever published, including new data on what's shared with a CC license.
We found nearly 900 million Creative Commons-licensed works, dramatically up from our last report of 400 million in 2010. Creators are now choosing less restrictive CC licenses more than ever before – over half allow both commercial use and adaptations.
We're also celebrating the success of open policy worldwide. Fourteen countries have now adopted national open education policies, and open textbooks have saved students more than 100 million dollars. These are big moves making big impacts.
