I never heard of this before, but it apparently happened back in the 1930's - newspapers trying to deliver their copy via radio over an early kind of fax machine.
It started when the papers began starting their own radio stations to try and compete with the new medium that was taking some of their business.
So how did the so-called "Finch system" work?
"First, image details were transmitted by varying the amplitude of an audio tone, instead of its frequency.
Second, it recreated the image by generating an electric current at the tip of a stylus to trace the image onto thermally sensitive paper (the origins of the thermal paper still used by cash registers today). Synchronization between the transmitter and receiver used the 60 Hz line frequency.
The Finch scanning head focused a pinpoint scanning spot on the document. A motor moved the scanner across the page while another motor advanced the page at the end of each scanning line. Low-frequency sync pulses were inserted at the end of each line. The result was an audio signal that could be fed into any conventional AM transmitter."
So in essence, you'd turn on the machine, it would tune into the radio station and then print out the newspaper right into your home. Pretty amazing for those days, but obviously pretty inefficient, as well. It lasted into the 50s and then faded into history.

I love posts like this, thanks RA! This is the first time I’ve heard of this, interesting idea. Had to laugh that it would experience content loss due to static! I wonder how noisy it was when in use…..
