[1] [2] These carbon filament bulbs, the first electric light bulbs, became available commercially that same year. [3] In 1904 a tungsten filament was invented by Austro-Hungarians Alexander Just and Franjo Hanaman , [ 4 ] and was more efficient and longer-lasting than the carbonized bamboo filament used previously.

CEO Wendell Weeks talks about Corning Inc.’s innovations—ranging from Edison’s lightbulb to the face of your smartphone—and how its fiber-optic cables are powering the AI revolution.
1878 – Thomas Edison, following work on a "multiplex telegraph" system and the phonograph, invents an improved incandescent light bulb. This was not the first electric light bulb but the first commercially practical incandescent light. In 1879 he produces a high-resistance lamp in a very high vacuum; the lamp lasts hundreds of hours. While ...
