In 1898, an immigrant inventor created a remote-controlled boat powered by a battery and operated it with the help of radio signals while everyone thought it was magic as the real reason was yet to become popular. The inventor was Nikola Tesla, who introduced the wireless-controlled boat during an electrical exhibition at Madison Square Garden in New York City. Visitors had never seen a machine respond to commands without wires. Since radio waves were not widely understood, many believed something unusual was happening. Tesla later explained that the boat worked through radio signals. His demonstration became one of the first public examples of wireless remote-control technology.
