Zworykin’s receiver, the kinescope, was superior to that of Farnsworth, however Farnsworth’s digicam tube, the picture dissector, was superior to that of Zworykin. Zworykin was enthusiastic in regards to the picture dissector, and RCA provided Farnsworth $100,000 for his work. He rejected the supply.
