Nikola Tesla was born in Croatia but lived in America for most of his adult life. Among his many ideas and inventions was his idea of transmitting electricity around the country using radio waves instead of wires, and while this system would have had some limited success, it would have severely impeded the development of conventional Radio and TV broadcasting, not to mention mobile phone technology and most forms of electronic device not very heavily shielded.
Our Tesla coil generates about a half million volts of radio frequency electricity, actually 200Khz, about the same as Radio 4 on long wave.
