Technological Foundations
The primary television programs operated on remarkably very simple nevertheless ingenious mechanical concepts. John Logie Baird's 1925 prototype utilized a Nipkow disk - a spinning disk with perforations organized in a spiral pattern. This mechanical scanner transformed illustrations or photos into electrical indicators via a photoelectric mobile, achieving a resolution of thirty lines at 5 frames for each second. Even though primitive, this breakthrough proved that television was attainable.
