label: Description (Brief)
content: A 1967 exhibition label reads: "Prior to the introduction of commercial television in the late 1930s, mechanical scanning techniques were employed in both transmitter and receiver. This unit employs a 48-hole spinning disc which turns in front of a neon [glow] lamp. Variations in light intensity caused by picture modulation result in the formation of an image in front of the scanning disc owing to the eye's persistence of vision. Lens magnification enlarged the viewing area somewhat, but lack of detail in this transmission system relegated the scanning disc to obsolescence."
