The Diaphote Hoax

Seems really Television was invented in the minds of people in the late 1800's even if like this Hoax

The electromagnetic spectrum has no theoretical limit at either end. If all the mass/energy in the Universe is considered a 'limit', then that would be the only real theoretical limit to the maximum frequency attainable.

Yes Harry, this is all science fiction of those days. Television and radio became possible by the invention of the triode valve in about 1907, as this made amplification possible. Without amplification no analogue (voice) radio and no grey scale picture television. Yes, radio started about 10 years earlier with spark transmitters and cohaerer detectors, but only in morse code, so digital radio.
