The story of a remote control

‘Lazy Bones’ was the trade name of the first remote control in the world. It was developed by the US corporation Zenith in 1950. The company founder, president Eugene McDonald, came up with the idea for the invention because he thought viewers would appreciate being able to ‘tune out annoying commercials’. Unfortunately, the first remote control wasn’t so remote because it was connected to the TV by a long wire – not a very comfortable thing if someone wanted to change channels from the kitchen – and, what’s more, potentially dangerous if someone went away for a while and tripped over it on return.

The first wireless remote control was produced in 1955. The invention was based on the idea of using photo cells to operate a TV set. The four gauges were installed in the corners of a television, and the remote itself was a kind of a flashlight called Flash-Matic. Its disadvantages became clear on sunny days, when daylight decided what to view and how high the volume should be set. Radio controls didn’t appear to be a good idea either because a stronger signal could change the channel in a neighbour’s flat!

The first idea that seemed to have none of the earlier disadvantages was conceived by a company engineer named Robert Adler and was called the Space Commander 400. This remote control used ultrasonic waves inaudible to humans and could change channels up and down, increase or decrease the sound volume, and also turn the power on and off. In its design, the Space Commander was in fact a little piano. Aluminium rods used to operate the control simply inducted sounds mechanically through miniature hammers. This idea even looks impressive nowadays when you consider the fact that no batteries were needed and, in order to change a channel, the remote didn’t have to be pointed at the television! Zenith patented the invention in 1956 and introduced the new product to the market. TV sets sold with this option cost up to 30% more but this didn’t scare the customers. It was then that the sociological phenomenon called the ‘couch potato’ started.

Before the 1980s, when the first remotes using infrared technology appeared, Zenith and other companies sold more than 9 million TV sets using Adler’s invention.
