There have been many different forms of television, but the electric version as it is known today was invented in 1922, and it first transmitted images in 1927. The person who invented this television was an Idaho schoolboy named Philo Farnsworth.
The first public demonstration of Farnsworth was in 1934, and his studio started broadcasting in 1936. These broadcasts were limited to 50 homes with receivers in the Philadelphia area, but they formed the foundation of broadcast systems. There were issues with RCA trying to break the patents that Farnsworth had on the system, but it lost and eventually began to pay royalties to use the system in 1939.
