Invention of the Television
In 1897, A German scientist Karl Braun experimented the cathode ray tube, "an enclosed glass tube with a electro-luminescent coating on the inside surface of one end. A spot on the coated surface would glow when struck with a beam of electrons" (). He used the tube as an "oscilloscope" in order to display tracks of electrical signals. Paul Gottlieb Nipkow, a student in Germany, created the first ever mechanical module of television in the late 1800s (). Nipkow's success concluded in sending images through wires with a rotating metal disk. At first, this module was called the ‘electric telescope’ that had 18 lines of resolution (). Along came the year of 1911 when two separate inventors, A.A. Campbell-Swinton and scientist Boris Rosing. These two inventors "used the cathode ray tube in addition to the mechanical scanner system, to create a new television system" (). With the experiments of Nipkow and Rosing, the "mechanical television" and "electronic television" came into exsistence.
