Remote control has continually evolved and advanced in the 2000s to include Bluetooth connectivity, motion sensor-enabled capabilities and voice control. In 1894, the first example of wirelessly controlling at a distance was during a demonstration by the British physicist Oliver Lodge, in which he made use of a Branly’s coherer to make a mirror galvanometer move a beam of light when an electromagnetic wave was artificially generated. Method of an Apparatus for Controlling Mechanism of Moving Vehicle or Vehicles, which he publicly demonstrated by radio-controlling a boat during an electrical exhibition at Madison Square Garden. Tesla called his boat a “teleautomaton”. In 1903, Leonardo Torres Quevedo presented the Telekino at the Paris Academy of Science, accompanied by a brief, and making an experimental demonstration. At the same time he obtained a patent in France, Spain, Great Britain, and the United States. By the late 1930s, several radio manufacturers offered remote controls for some of their higher-end models.
The first remote intended to control a television was developed by Zenith Radio Corporation in 1950. The remote, called “Lazy Bones”, was connected to the television by a wire. In 1956, Robert Adler developed “Zenith Space Command”, a wireless remote. It was mechanical and used ultrasound to change the channel and volume.
