In the 1980's and 90's I participated in many videos and manuals full of pictures and process. I would completely rebuild products while the video team taped. Then they would edit this (without my mistakes) into technical videos and service manuals. Then as we moved into the digital age, most of this was archived and lost. Everything new was about "New". Digital storage was huge and costly. Since then I have not seen many of those early videos again. It would be nice to find old videos people have done and have them on a disc so we could watch them without the internet. Sadly it seems a lot of that old technical training stuff is gone.
