YouTube Video Mash-up
A YouTube Video Mash-up is the combination of multiple sources of videos which usually have no relation with each other, other than a derivative work, often
lampooning its component sources or another text. Many mash-up videos are humorous
movie trailer parodies, a later genre of mash-ups gaining much popularity. To the extent that mash-ups are 'transformative' of original content, they may find protection from copyright claims under the "
fair use" doctrine of U.S. copyright law.
