YouTube added a new feature that lets you change the standard video licensing and switch to the Creative Commons Attribution license, which allows other people to reuse your videos. "Others may copy, distribute and create derivative works from your video — but only if they give you credit."
The new feature is used in YouTube's video editor, which lets you search for Creative Commons videos and use them to create a new video. YouTube says that there are already more than 10,000 videos from organizations like C-SPAN and Al Jazeera, but that's just the beginning.
YouTube will certainly become the largest library of Creative Commons videos, but it's strange to see that it took so long to add a license that encourages creativity. The first Google service that integrated with Creative Commons was Google Web Search (2005) and it was followed by Picasa Web Albums (2008) and Google Image Search (2009).
If you want to find Creative Commons videos on YouTube, click "Filter & Explore" after performing a search and select "Creative Commons". You could also add ", creativecommons" to your query and search for [paris, creativecommons].
