ABOUT TELEVISION

The television has become such an integral part of homes in the modern world that it is hard to imagine life without television. The boob tube, as television is also referred to, provides entertainment to people of all ages. Not just for entertainment value, but TV is also a valuable resource for advertising and different kinds of programming.

The television as we see it and know it today was not always this way. Let’s take a brief look at the history of television and how it came into being Different experiments by various people, in the field of electricity and radio, led to the development of basic technologies and ideas that laid the foundation for the invention of television.

In the late 1800s, Paul Gottlieb Nipkow, a student in Germany, developed the first ever mechanical module of television. He succeeded in sending images through wires with the help of a rotating metal disk. This technology was called the ‘electric telescope’ that had 18 lines of resolution.

Around 1907, two separate inventors, A.A. Campbell-Swinton from England and Russian scientist Boris Rosing, used the cathode ray tube in addition to the mechanical scanner system, to create a new television system. From the experiments of Nipkow and Rosing, two types of television systems came into existence: mechanical television and electronic television
