Also, there was Philo Farnsworth, a west-coast inventor whose first demonstration of television was in 1927. Like Baird's system, it was electro-mechanical, but by 1929 he had eliminated the moving parts of his system to create the world's first fully electronic system.
The history of the television can be dated back to the late 1800âs when inventors experimented with ways to have signals transmitted to a receiver. In fact, the first coaxial cable (commonly used to distribute cable TV signals) was invented during this time. The first actual transmission of images was successfully completed by John L. Baird in 1925, which led to rapid developments in television in subsequent years.
