When did you last send someone a photo? That question may sound odd, owing to the sheer commonness of the act in question; in the twenty-twenties, we take photographs and share them worldwide without giving it a second thought. But in the nineteen-thirties, almost everyone who sent a photo did so through the mail, if they did it at all. Not that there weren’t more efficient means of transmission, at least to professionals in the cutting-edge newspaper industry: as dramatized in the short 1937 documentary above, the visual accompaniment to a sufficiently important scoop could also be sent in mere minutes through the miracle of wire.
“Traveling almost as fast as the telephone story, wired photos now go across the continent with the speed of light,” declares the narrator in breathless newsreel-announcer style. “It’s not a matter of sending the whole picture at once, but of separating the picture into fine lines, sending those lines over a wire, and assembling them at the other end.”
Illustrating this process is a clever mechanical prop involving two spindles on a hand crank, and a length of rope printed with the image of a car that unwinds from one spindle onto the other. To ensure the viewer’s complete understanding, animated diagrams also reveal the inner workings of the actual scanning, sending, and receiving apparatus.
This process may now seem impossibly cumbersome, but at the time it represented a leap forward for mass visual media. In the decades after the Second World War, the same basic principle — that of disassembling an image into lines at one point in order to reassemble it at another — would be employed in the homes and offices of ordinary Americans by devices such as the television set and fax machine. We know, as the viewers of 1937 didn’t, just how those analog technologies would change the character of life and work in the twentieth century. As for what their digital descendants will do to the twenty-first century, as they continue to break down all existence into not lines but bits, we’ve only just begun to find out.

Transmission of a photo via wire forms the climax of the 1947 James Stewart film “Call Northside 777.”.
and yet, ironically even with technological advancements in 2023 i cannot watch the video, simply and only because i don’t live in america. because in this future the world outside of america simply doesn’t seem to exist.
Fascinating, but surely the reality is that today we do exactly the same thing to transmit photos there is nothing new, is there?
Interestingly, we were still using this technology in 1994 for fast robust transfer of images on the battlefield. The difference was the receiving end used a voice coil driven hammer to tap out the picture onto a carbon paper/paper on the rotating drum. That technology has finally been outmoded.
