The First Wireless TV Remote Had a Crazy Problem #shorts #documentary || TVRemote || Inventions || RemoteControl || TVHistory How was the TV remote control invented, and what did people use before modern infrared remotes? In the early days of television, changing the channel meant getting off the couch and walking over to the TV. Then everything began to change. In 1950, Zenith introduced Lazy Bones, an early wired TV remote control that allowed viewers to operate their television without leaving their seats. But the cable running across the room created a new problem. Engineers needed a wireless solution. In 1955, Zenith engineer Eugene Polley developed the Flash-Matic, the first wireless TV remote control. Instead of radio waves, Flash-Matic used a directional beam of light aimed at photocells around the television screen. Different sensors controlled different TV functions. It was innovative—but it had one major weakness. Sunlight and other bright light sources could accidentally trigger the television. Then Zenith engineer Robert Adler developed a completely different solution. Ultrasound. The Zenith Space Command remote used aluminum rods that produced ultrasonic frequencies when struck by tiny spring-loaded hammers. The original remote required no batteries. Each ultrasonic frequency represented a different command. In 1956, Space Command went into production and helped transform television remote control technology. Ultrasonic remotes remained important for roughly 25 years, with more than nine million ultrasonic remote-control televisions sold across the industry before infrared technology became dominant in the early 1980s. Today, most traditional TV remotes use infrared light to send digital commands. But the basic idea remains the same: Press a button. Send a signal. Make the television respond from across the room.
