Thomas Edison is usually credited with the invention of the light bulb, but the famous American inventor wasn't the only one who contributed to the development of this revolutionary technology.
Thomas Edison is most well known for the invention of the light bulb, even though he didn't actually invent it. Light bulbs were already around, but they were expensive and very unreliable. He expanded on the light bulb idea by creating a vacuum inside the bulb and sending a lower volt of electricity into it. After his improvements, the light bulb lasted many more hours than it did before. He continued to expand the idea of electricity by building electrical systems, motors, and other appliances. Thomas Edison also invented the early form of movies - the motion picture.
