June 16, 1969: The gadgets were on display at an annual consumer electronics expo at two Manhattan hotels.
Crowds who jammed corridors and rooms of a total of nine floors in the two hotels were treated to a mass exhibition of the latest in radio, television, tape recorders and other electronic devices.
There was an automobile alarm that blurted out a pre-recorded cry like this:
‘Help! I am a black Buick Riviera, New York license No. XXX. I am being stolen! Help! Call the police!’ The New York Times reported.
Also shown was a Panasonic FM stereo radio headset that made a listener look like a ‘man from Mars’ with two antennas pointing out.
