Creative Commons announced on June 2, 2011 that You Tube has added Creative Commons BY as a licensing option for users. You Tube users can now choose to license their video under CC BY or use the “standard You Tube license”.
You Tube, in conjunction with the implementation of the CC license, has launched a Creative Commons video library containing 10,000 videos under CC BY from organizations such as C-SPAN, PublicResource.org, Voice of America, and Al Jazeera. The library will serve as a base catalog of videos for users to access, edit, and incorporate into their own video projects.
