CC licensing commercials, at least under a restrictive Attribution-NonCommercial-NoDerivs license, seems like a no-brainer (adverisers should want their message spread as much as possible) and allowing derivatives not much of a stretch (going “viral” and all that), but not many have taken these steps.
Now multimedia pioneer Marc Canter has published a commercial for his PeopleAggregator startup under our liberal Attribution license. I don’t suppose Marc would mind if you made him “go viral.”
Watch the commercial. Also note that PeopleAggregator, an “open social network”, enables CC licensing of user created images and videos.
