The person that actually made TV was none of the above. Vadimir Zworykin working for David Sarnoff at RCA was able to tie up all the technology, monopolise it with patents and refine it for mass production. The popular narrative was that the technology was stolen from Farnsworth, but even so, it still took all of the resource of RCA to build the hardware to capture, broadcast and receive television, mass produce it in quantities of millions and have the political clout to obtain the radio bandwidth from the federal government needed to broadcast the signal.
