I was interested to find that YouTube now has a Creative Commons option for their uploads. The ability to share content with others and also allow them to adapt for their own needs it good for all open source users, this addition is certainly an added bonus. Although as pointed out by a colleague this does not include the Non-Commercial (NC) part, which your educational establishment or company may prefer, not forgetting those wishing to make money from their work.
Looking at the details provided by Youtube it quotes:
For more information on the CC-BY license—a summary of the full Legal Code with the full license accessible at the bottom of the page—please visit this page on CreativeCommons.org.
If your dont want other companies using your content, then probably steer clear of this option, it may not be the best option. Perhaps YouTube will also provide an option that has NC in the future? Could be handy.
This creative commons page actually states its an:
