-or the "scope"
-some American guy experiments with mechanical machine called a telectroscope using Telegraphy in the 1890s using rotating disk (but very low resolution), doesn’t work on regular telegraph lines however
-in 1897, able to get it working on coaxial cable [figure out name]and also replaces rotating disk with rotating drum, broadcasts cricket match successfully in huge stunt (but still an unworkable technology for broad use)
-experiments with Photonics to do it, finds they work
-takes full use of long-range photonics, to transmit using it in 1909
-but unable to take it to market, even after that
-only in 1920s, with commonality of photonics, does it (with new marketable name of photonoscopy) become a consumer product (but even then a niche one but growing over 1930s)
-results in development of market for photonic plays paired with photescopic performance
-and also some news with talking heads, and performances
-however, leaves much to be desired - hard to have impressive resolution without it being too huge (and at that point just use film) and noisy operation
-exodal wave tube (EWT) however becomes a big thing
-some German guy develops EWT photescope (word has lost its s and o, with first o turned to e, in the end) in 1930
-proof-of-concept for a few more years, just about to be brought to market when French Wars > Sixth French War (1937-41) hits
-postwar, doesn't really do as well because it's much more expensive than mechanical sets, so despite its obvious superiority it takes a while
-but in general, photes (Photonics > ^42a5b9) preferred despite being audio-only just because mechanical sets very noisy
-effort brought along by channels switching over, and by 70s it's absolutely dominant and spreads far and wide into households
