Copyright

For protecting your creative content

Generally, any creative works you make, such as, but not limited to, videos and photos, are subject to being protected by U.S. Copyright Law as copyrighted works.

Also, as content creators, you want to learn how to avoid allegations that your creative works are infringing copyrights of others.  This often occurs when you use music of others without permission and with reaction videos.  There are safe ways to use music in your creative works. 

Additionally, never use a video and/or a photo of another without permission from the copyright owner or a written license to do so. 

And there can be best practices to lower the odds of having issues if you are doing reaction videos.
