When Did The Idea of TV Start

You know guys, until I decided to look into TV and when was it invented I had no idea that the idea and conception was sooo.. long ago.

I talked to my husband about it as he had a radio shop when he was in high school and he said that the first TV he had seen was at the San Francisco World's Fair in 1939. He had never fully delved into it either but learned a lot when he became a TV technician in 1949.

Anyway the origins can be tracked back to a discovery called photoconductivity of an element called selenium in 1873. See! I said it was a really long time ago. Then a guy invented what they called a scanning disk in 1884, and then the invention of an image dissector in 1927. For the real detailed skinny check out Wikipedia.

The very first patented electromechanical television system was in 1884. Who knew!! It was first read about at the International World Fair in Paris in 1900. Inventor's all over were experimenting with something called a cathode ray tube and using this created the first TV's that RCA purchased the patents for.

Well kiddies, we'll continue on from here in the next installment. Chao!
