According to Wikipedia's short article on OneTimes Square:
' On November 6, 1928, an electronic news ticker understood as the Motograph News flash (colloquially understood as the 'zipper') was introduced near the base of the building. The zipper initially included 14,800 light bulbs and a chain conveyor system; specific letter aspects (a kind of movable type) were packed into frames to define news headlines. As the frames moved along the conveyor, the letters themselves set off electrical contacts which lit the external bulbs (the zipper has actually since been upgraded to use contemporary LED technology).'
An example of this was seen in the 1933 Warner Bothers movie 'Picture Snatcher' starring James Cagney. This example motivated Moving Headings JNL.
