Media is a word that means any kind of art. It could be pictures, video, music, or something else entirely! But if it was created by someone, that person owns it and has the right to say who can and can't use it. When you search the web for images, music, or video, you can find all kinds of media, and just because it's there doesn't mean the owner has given you permission to use it. This page will help guide you in understanding copyright rules, finding media, and using it in a way that respects copyright.
Public domain resources are music, photos, and videos owned by the public. They are either created by government employees or donated to the public. You can use them in any of your projects in any way, without fear of copyright infringement.
