From YouTube Channel:  The AT&T Tech Channel

I love videos from the era when power and communications were just getting started.  This video is a classic on new technology that seems so advanced (and probably very expensive) for a large campus-based sized company such as a farm or supply yard.

For some reason, while I know how great and easy new technology is for us today, this is still an interesting video that I'm sure was such an advanced technology that worked extremely well for it's time.
