In 1936, RCA engineers were still working fast & furious trying to develop a feasible television broadcasting system, from studio design to receiver design. They had the basics down pretty well by then, but apparently a lot of what they were working with was about at the technical limits of what was possible to produce then..."Kinescopes"-picture tubes- had tiny screens- 4X6 inches, yet were as long as a man's arm. 441 line images were The Bee's Knees, I think they were aiming for pictures that were at least as good as newspaper photos.TV was alive & well in '36, but it was VERY primitive.
