Pallophotophone

The world’s only working (modern) Pallophotophone plays 80-year-old NBC radio broadcasts:

The pallophotophone was an early audio recorder created by GE researcher Charles Hoxie in 1922. Rather than using magnetic wire or lacquer disks, the device captured audio waveforms on sprocketless 35 mm film as a series of 12 parallel tracks reflected from a vibrating mirror. It was used to record some of the world’s oldest surviving radio broadcasts on Schenectady, New York radio station WGY between 1929 and 1931.

As a forgotten optical medium, I guess its more modern analog would be laserfilm discs. Sort of working along the right path, but just not practical compared to other media coming out at the time. There’s more about the rediscovered pallphotophone recordings on the GE Reports blog.

This “creative destruction” began in the ’60s, as did many things that we now both love and regret, and it was initially a spinoff of a project funded by US military agencies. […] Mephistopheles came to Faust in the form of a poodle. After all…in some versions of the story, he cannot enter your house unbidden — you have to invite him in, like a vampire.

From Internet Antichrist, a thoughtful piece by David Byrne on the the development of the ARPANET, psychoacoustics research at Bell Labs leading to vocoders and Kraftwerk, the rise of digital recording and transmission, and the possibility of the near-future demise of physical media and risks to personal privacy. The market forces of creative destruction.
