Cathode Ray Tube (called the kinescope in 1929)Born in Murom, 200 miles east of Moscow, Zworykin at age nine started spending summers as an apprentice aboard the boats his father operated on the Oka River. He eagerly helped repair electrical equipment, and it soon became apparent that he was more interested in electricity than anything nautical.
At the Imperial Institute of Technology, Boris Rosing, a professor in charge of laboratory projects, became friendly with the young student engineer and let him work on some of his private projects. Rosing was trying to transmit pictures by wire in his own physics laboratory. He and his young assistant experimented with a primitive cathode-ray tube, developed in Germany by Karl Ferdinand Braun. Significant Dates and Related History of Develpments which preceded the invention:Zworykin invented the cathode-ray tube called the kinescope in 1929Zworykin also invented the iconoscope in 1923 — a tube for television transmission used in the first cameras. On November 18, 1929, at a convention of radio engineers, Zworykin demonstrated a television receiver containing his kinescope. The only preceding technology to this was the work he did in the Imperial Institute of Technology with Boris Rosing.
There is no way to measure the impact of the Television on or society. It plays an important part in almost everything we do. It has somewhat balanced the transportation of media so giving all members of our society the same information in a timely and informative manner. TV has influenced us in so many ways its impossible to list.
Not a day goes by when most people have seen at least half an hour of Television. Most recent developments and/or changes in the invention:We have moved from the basic black and white screen to projection Televisions to movie theaters. The cathode ray tube has been adapted to be used as a visual aid for radar and many other important things.
