Where did the tv come from?

A man named Philo Taylor Farnsworth was a American inventor and television pioneer. He made a lot of contributions that were viable to the early development of the electronic television. He is best known for inventing the very first full functional all-electronic image pickup device. He called it the "image dissector". He was also one of the first people to show this to the public. He developed a television system with a receiver and a camera, which he sold commercially in the firm of the Farnsworth Television and Radio Corporation, from 1938 to 1951.
