Pictures by Radio (Jun, 1939)
The printout actually looks really good, though at 3 feet per hour it isn’t the most useful thing in the world.
Pictures by Radio
RADIO facsimile, the process by which pictures and printed matter are transmitted over the air for identical reproduction at the receiving end, is rapidly advancing as a new and valuable service of radio broadcasting. An experimental facsimile network has been established as part of the Mutual Broadcasting System, and already three important stations, WGN, WOR and WLW, are transmitting on regular schedule. Factory-made receivers of medium price are being produced by a large radio set manufacturer and are now advertised and sold by department stores.

This is the earliest reference I’ve seen to a CCD in a consumer product.
Amazing New Picturephone
A step closer to in-person
By W. Stevenson Bacon
Thereâ€™s a brand-new Picturephone in the works that will one day give you instant total communication with anyone you call. What makes it fascinating is the amazing versatility of the delicately engineered unit that holds both picture and camera tubes.
Unlike the old Picturephone, this one gives you a choice of wide-angle picture, long-range shot, or electronic close-up. Pull a lens out and aim it downward, and you can send pictures, drawings, or printed documents. If you wish, you can push a button to see what youâ€™re sending. And if a call catches you in the shower you can simply switch over to three-bar test pattern.
Bell Telephone Laboratories packed all this into an 8-by-11-by-14-inch box by using tiny integrated circuits that incorporate hundreds of transistors and other components on small chips of silicon. In fact, the only vacuum tubes used are the picture and camera tubes. And even the camera tube makes use of semiconductors.
The camera tube is a revolutionary new type that uses a target (the part of the tube that converts incoming light to electrical charges) made of silicon and containing 300,000 light-sensitive diodes formed on it by integrated circuit techniques. Itâ€™s the first time that semiconductors and vacuum tubes have been combined to make one device.
Dial Switches Message Tubes (Dec, 1951)
This is a hardware packet switched network, kinda like IP circa 1951.
Dial Switches Message Tubes
By Dialing a number, workers in a Connecticut factory can send written messages and even metal samples to various parts of the plant in about a minute’s time. They are using the familiar old pneumatic tube, the hissing clanging gadget used to make change in many department stores.
This pneumatic tube is different. Wehere older systems required separate tubes to each station, this one has an automatic dial exchange, just like a modern telephone central office, making a few tubes do the work of many. Each carrier has numbers that can be set to guide it automatically to any one of the nine stations that make up the first American installation at the Housatonic plant of the Bridgeport Brass Co. Eventually there will be 20 stations.
