Introduction

Experiments using electricity to transmit video began back in 1884. In 1926, English experimenter John Logie Baird developed a system for transmitting live video images using a mechanical system. The mechanical system was primitive by today’s standards, and other methods were tried to achieve a better picture. Beginning in the 1920s, other experimenters attempted to use an electrical system for television. Philo T. Farnsworth and Vladimir Zworykin both developed systems that eventually were combined to create the working television system that debuted at the 1939 World’s Fair in New York.
