1941 | April 30 – North America’s current 525-line NTSC (National Television Standards Committee ) standard of picture definition was adopted by the Federal Communications Commission. The FCC also authorized commercial television to begin on July 1. The first transmitters were installed in the capital cities (London, United Kingdom, Paris, France, Berlin, Germany, Rome, Italy, New York, New York), so only a small proportion of each country was therefore able to benefit.
