Copyright law has fascinated me since high school. I read a lot about it, I understand it (fairly well), I have a lot of informed opinions on it, but I have never been able to articulate my ideas on the subject in the way that I am confident.
Fortunately, law professor and Creative Commons founder Larry Lessig does it for me. His presentation perfectly explains Copyright law, then he breaks it down in ways that make so much sense. So much more sense then I could ever make. Not only that, the presentation uses PowerPoint in fun ways.
This isn’t short, but if you have any curiosity or interest in Copyright law and how it impacts you, watch this video. If you don’t have a lot of time, watch the first twelve minutes, and the last five; you won’t regret it.
