(Compagnie générale de la télégraphie photonique)
-in 1894, inventor Frédéric Antoine Lombardi, working on harmonic telegraphy, finds a spark gap produces a spark in nearby relay, allowing wireless transmissions
-over the next few years he tests it out, rules out that it's some faraway induction, and publishes his inventions in 1897 and talks about it being "aether waves" akin to exodal waves
-makes various experiments with help, measures speed and notices it's identical to light
-makes additional experiments, finds its reflection and refraction is a form to light
-and finds that it cannot be deflected with a magnet like exodal waves, but can be polarized like light
-and thus concludes that it is, in fact, light
-unbeknownst to him, Schrader came up with electrodynamic theory (Electrodynamics > ^adc7f8) that ensures this finding achieves widespread scientific recognition
-with telegraphy achieved Lombardi works on it
-after extending range to 500 metres, markets it to ships and the like
-expands the range further and further, but hits limit at 2 1/2 km
-in 1907, competitor Jean-Baptiste Kowalski able to extend limit through raising antenna and grounding both transmitter and receiver, is able to sell this better than Lombardi did his
-when he sees his bottom line go down, Lombardi concludes by selling invention to government of French Republic and benefits handsomely when French govt promptly gives itself a monopoly like it has on telegraphy
-in 1919, a group of French investors come together and form a company operating photonic lines across Atlantic, other places
-they quickly go on to create photes for consumer consumption in 1920s, becomes biggest such company
-even going on to create thermex photes in 1930s, creating a lot of thermex valves
-and becoming big on [telephones]
-very prosperous company
-during French Wars > Sixth French War (1937-41)), this production of thermex valves escalates with rise of war as it produces them for warfare
-postwar, boom of thermex valves, golden age of thermex photes, CTP booms
-a lot of modernized factories develop in Aix-la-Chappelle in reconstructed region
-center of CTP business moves eastward, where it remains to this day
-comes up with [nuvistor], 1960s boom makes it big
-also develops Photescopy
-quickly acquires patent to crystal valve when invented (Biodes and terodes > ^523202) and in 1970s and 1980s becomes big
-also when used by Analyzers becomes analyzer company in many ways
-[personal computer] revolution in noughties, CTP is major part of it
-including communications in Networking > Réstéf ( French Republic ))
