Zenith Flashmatic - the first TV remote control

The Zenith Flashmatic was a flashlight-powered opto TV remote controlThe Flashmatic was the first TV set to offer a remote control, and it was operated using a raygun-like device that was basically a torch (flashlight).

Aiming it at one of the four corners of the TV would turn the set on or off, mute the sound (TV commercials were annoying even back then!), or it could change the channel - a photocell circuit operated a motor that turned the channel selector turret tuner clockwise or anti-clockwise, no doubt with a satisfying clunking and clattering sound.

It was a nuts valve (vacuum tube) design that was destined to fail, because it proved all too easy to trigger using false beams of light (eg sunlight or reflections). Next came sonic-operated TVs, that had a mini-chime bar type of remote control. Different frequencies triggered different functions on the TV. A 'clicker' type of remote device was also marketed.
