Professor William Fisher (William Fisher) is known as a specialist in copyright law. He deals with the issues of legal copyright issues for many years, and regularly lectures on copyright in Garage. Video of lecture Fischer was recently posted on YouTube, but the video had to block her claim by Sony Music.
The lecture by the Professor was part of his online course, CopyrightX, licensed under Creative Commons Attribution 4.0 License. There is a specialist copywriting and offline video that can be downloaded from his website, so much harm blocking one lecture to no avail. However, it is interesting precedent.
