I believe the first video tape recorders from Ampex, Mod. 1000? Serial numbers 1 & 2 were installed in the old TVR in Grand Central. They were only accessible to a privileged few, of which I was not one. I could only look at them from a distance. They did not last long in that location, as it was decided to move them up to the fourth floor, and that started the video tape department. The first operators were Marty Murphy and Red Steiger.
This was around 1957.
