Who invented the first remote control is untestable, but one of the earliest remote controls was an inventor named Nikola Tesla (1856-1943) (he used to work for Edison) , Also known as a genius inventor) was developed in 1898 (US Patent No. 613809), called "Method of and Apparatus for Controlling Mechanism of Moving Vehicle or Vehicles".
The earliest remote control used to control the TV was an American electrical company called Zenith (this company is now acquired by LG), invented in the 1950s, and it was wired at the beginning. In 1955, the company developed a wireless remote control device called "Flashmatic", but this device could not tell whether the light beam came from the remote control, and it also had to be aimed to control it. In 1956, Rob. Robert Adler developed a remote control called "Zenith Space Command", which is also the first modern wireless remote control device. He uses ultrasonic waves to adjust the channel and volume. The frequency of each button is different. But this kind of device may also be disturbed by ordinary ultrasound, and some people and animals (such as dogs) can hear the sound from the remote control.
When semiconductor devices that transmit and receive infrared rays were developed in the 1980s, they gradually replaced ultrasonic control devices. Even though other wireless transmission methods (such as Bluetooth) continue to be developed, this technology continues to be widely used until now.
