But of course no videophone between households. Strange enough, there were many attempts to establish a videophone service, the last big attempt was in the late 1980s, here it was called "BIGphone", working via ISDN. But nobody wanted it. Even now, when you can have a video-line using Skype or similiar apps via your smartphone, hardly anybody is using it. Mostly for video conferences in the industry or deaf people, the same like in 1936 in Germany...
I think your right on the video phone i am not really into the video chatting apps and i don't know how easy they are to use but watching my family with this stuff they tend to just use it between them not strangers and very rarely .
Its interesting that this sort idea for the use for television has been around before television was invented .
People just don't like the idea of it
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.
