Remote Control
1. The earliest example of remote control by radio waves was developed in 1898 by Nikola Tesla and described in his patent, named Method of an Apparatus for Controlling Mechanism of Moving Vehicle or Vehicles. In 1898, he demonstrated a radio-controlled boat to the public during an electrical exhibition. Tesla called his boat a «teleautomaton».
2. The first machines to be operated by remote control were used mainly for military purposes. Radio-controlled motor-boats, developed by the German navy, were used to ram enemy ships in WW I. Radio controlled bombs and other remote control weapons were used in WW II. Once the wars were over, the United States scientists experimented to find nonmilitary uses for the remote control. In the late 1940s automatic garage door openers were invented, and in the 1950s the first TV remote controls were used.
3. The first TV remote control, called «Lazy Bones», was developed in 1950 by Zenith Electronics Corporation (then known as Zenith Radio Corporation). «Lazy Bones» used a cable that ran from the TV set to the viewer. A motor in the TV set operated the tuner through the remote control. Although customers liked having remote control of their television, they complained that people tripped over the unsightly cable that meandered across the living room floor. Manufacturers used to only make remote controls that operated one TV set. However, they are now making universal remote controls that can operate any TV set. Experts predict that someday remote controls will control almost every device in the home.
