The complete State of the Commons 2015 report is linked to at the bottom of this post.
From a CC Blog Blog Post:
Creative Commoners have known all along that collaboration, sharing, and cooperation are a driving force for human evolution. And so for many it will come as no surprise that in 2015 we achieved a tremendous milestone: over 1.1 billion CC licensed photos, videos, audio tracks, educational materials, research articles, and more have now been contributed to the shared global commons.
From a CC News Release:
Creative Commons works in over 85 countries to lead this expanding global movement. A major factor in its growth are official translations of the Creative Commons Version 4.0 license suite. To date, the 4.0 license suite has been translated into 7 languages, with 3 more languages to be published before the new year. In 2015, people viewed content under Creative Commons more than 136 billion times.
More than 50 cultural institutions have made their permanent collections or records available for liberal use around the world under CC licenses or public domain tools. Forms of content shared include photos, videos, research articles, audio tracks, training materials, and other educational resources. Major platform partners including Flickr, Wikipedia, 500px, Medium, Vimeo, and YouTube among others have helped to grow the number of CC licensed works, participating in a worldwide effort to expand the commons, along with millions of individual websites.
Highlights from this year’s State of the Commons report include the following:
CC licenses continue to be the global standard for sharing: CC-licensed works passed the 1 billion mark this year, and have nearly tripled in the last 5 years, signaling an exciting increase in the number of people choosing to share content.
Velocity of change: The CC-marked public domain is growing rapidly and has nearly doubled in size over the last 12 months.
Openness is far reaching: People are using CC licenses to share in as many as 34 different languages. Creative Commons now has affiliate institutions located in 85 countries.
Advances in Foundation policies: In 2015 a significant number of foundations switched their granting default from “closed” to open, including the Ford Foundation, Wikimedia Foundation, Vancouver Foundation and the Bill & Melinda Gates Foundation. These open funding policies ensure maximum impact of and access to Foundation-funded resources.
Momentum in the digitization of culture: The realization that there is a business and societal case for online sharing around culture–even in the presence of extremely divergent points of view–has resulted in museums opening their collections to share with the world under Creative Commons licenses and public domain tools. The Netherlands’ Rijksmuseum is leading the charge by digitizing collections.
A shift towards sharing in government: The proposed U.S. Department of Education open licensing policy will ensure government funded educational materials are openly licensed and freely available to the public that paid for them. Access to these materials will be open by default rather than require people to pay twice (or more) for access.
Open education movement goes mainstream: To date, the open education movement has delivered $174 million in savings to students through open textbooks.
Platforms as partners: Support and growth of openly-licensed content continues on platforms such as Wikipedia, Europeana, and Flickr, with new platform partners like Medium and edX.
