Whose light bulb lit the world?
Quick Answer

The Full Story
Thomas Edison is popularly credited with the light bulb, and in 1879 he produced the first practical, long-lasting incandescent bulb, using a carbon filament that could glow for many hours. Edison did not invent the very first electric light — several inventors, including Joseph Swan in Britain, worked on similar designs — but he made it reliable and part of a complete system of power generation and distribution. His work helped bring electric lighting into homes and streets around the world.
