I have been looking for a documentary I saw maybe 10 years ago. I think it was called the History of the VTR. It focused on the VTR as part of broadcast television. And I vaguely remember a section talking about the kind of errors and how they would present themselves in the broadcast. If anyone know about / remembers / knows where to find this documentary, I would be thankful!
