Imagery is the key to understanding TV, and there are several angles we could select in order to evaluate the impact of this imagery on our lives. We could look at biological or physiological impacts, or we could look at cultural or social impacts, even political and economic.1

In 1922, an American farmer and electronics tinkerer by the name of Philo T Farnsworth invented a scanning device that would lead to the development of television. Farnsworth's 'image dissector' solved many of the problems faced by European and American technicians who sought a way to electronically transmit images. Control of Farnsworth's invention would determine the success or failure of all television development.
