On the staff of the Radio Corp. of America after 1929, he became vice president and technical consultant of the corporation in 1947 and honorary vice president and consultant in 1954. In recognition of his many achievements he was awarded the National Medal of Science in 1967. His important researches in electronics enabled him to develop with his coworkers the iconoscope, a scanning tube for the television camera, and the kinescope, a cathode-ray tube in the television receiving apparatus. A group under his direction produced (1939) an electron microscope. Zworykin is coauthor of Photocells and Their Application (1930, rev. ed. 1934), Television (1940), Electron Optics and the Electron Microscope (1945), Photoelectricity and Its Application (1949), and Television in Science and Industry (1958).

After 1929 he worked at the Radio Corporation of America (RCA), heading electronics laboratories in Camden and Princeton (N.J.).

In 1931, Zworykin built the first iconoscope, a transmitting tube that made possible the development of electronic television systems. Zworykin is known for his work on photocells, electron multipliers, and electron microscopes, as well as electronic traffic control systems. From 1954 to 1962 he was the director of a center of medical electronics. Since 1954 he has been an honorary vice-president of RCA.
