Television's Magic Moment and the Electromagnetic Spectrum

Television changed the world between 1950 and 1962, with households owning sets increasing from 9% to 90%. However, the magic moment of television was a byproduct of the electromagnetic spectrum. Light at different frequencies, including high frequency rays, enabled communication and television. The spectrum is scarce, with limited availability for each use. The invention of radio and television had a significant impact because they quickly moved to a network model, enabling people worldwide to see the same content. This network model aligned with the economics of scarcity and created a cultural shift towards a nationwide or global focus.
