However, not all content on these platforms is covered by copyright, and that can potentially lead to complications, since policies are often built off of the assumption that everything must be covered by some form of copyright. > Australia-based music technologist Sebastian Tomczak, who has a PhD in computer generated music, created from scratch a 10 hour “low level white noise” recording, which he placed on YouTube. He created the file himself, then made a video version of it, and posted it to YouTube. In early 2018, he discovered that there had been five separate copyright claims on the video from four separate copyright holders.
