The television was invented through the efforts of a lot of people. The word television was not used until 1900 at the World's Fair in Paris. The first televised image with moving images was in 1926. We've come a long way from heavy, bulky black and white televisions to colored flat screens, that are light weight, with high definition.
The very first television was made in 1928. It had a large cabinet and a very small screen. It was made by General Electric and was called The Octogon. You can find more information here: http://www.tvhistory.tv/pre-1935.htm
