The history of radio dates back to centuries ago and many people seem to be associated with it. Apart from James Clerk Maxwell there are many people who contributed to the idea of radio, some of the most famous are Michael Faraday, Friedrich Kohlrausch, Wilhelm Weber, and Heinrich Hertz. These were the people who contributed in one way or other for the development of radio.

Similarly, history of television also involves work of many scientists and engineers who work directly or indirectly for the invention and development of television. Just like history of radio, the history of television is also very vast and rich involving many people from many countries. So it would be wrong if we just mention the name of one person as many scientist, technicians, engineers work in their fields what we are seeing today as television.

Earlier television was mechanical as well as electronic gadget but later it became purely electronic item. So we can safely say that the foundation stone i.e. electromechanical principles were taken over by purely electronics as we are seeing it today. Actually, Maxwell was very impressed with electromagnetism related work of Michael Faraday. The main turning point in the development of radio started with the technical paper on Faraday’s ideas on electromagnetism by Maxwell in 1855.

On the similar lines, the invention of television also involves work from several technicians, scientists and engineers who worked in different fields. Basically there are two different fields of technologies: early inventors tried to build a mechanical television on the basis of rotating disks technology by Paul Nipkow, whereas later electronic television was developed on the basis of cathode ray tube (CRT) in 1907 by English inventor Campbell and Russian scientist Boris.

We all know that over the period of time these were electronic television systems that replaced mechanical television technology due to obvious reasons, such as better performance, low heating and low power consumptions.
