Of all the contributions made by individuals towards the realisation of an all-electronic television system in the USA, none were of greater importance than those of Dr. V.K. Zworykin. His invention and development of the iconoscope and development of the cathode-ray tube as a television display tube (which he called a kinescope) were outstanding in conception and execution. The tubes were essential components of RCA's high-definition television system of the 1930s, and the iconoscope was the forerunner of a family of electronic camera tubes manufactured by RCA.
