Zenith VHS Hi-Fi Demo from 1984

This clip comes from a VHS demo tape Zenith provided to dealers in 1984 to educate them as to how VHS HiFi differed from the longitudinal audio recording that VHS recorders had used up to them. Plenty of diagrams were distributed to dealers and the press to explain this, but this early digital video makes it easier to understand. Why this video was made available only to dealers and not to the general public remains a mystery.
