A long time ago, in the early 1800s, people started trying to make electric lights. One man from England sent electricity through a piece of metal called platinum, and it made light.
But it took 50 more years to make a light bulb that could last longer. They needed to find the right material to use.
Thomas Edison wanted to find this right material. He had a great team, and they worked really hard.
On October 21, 1879, Edison made a new kind of light bulb. This light bulb stayed on for 13 and a half hours.
The newspapers said it was a big success, but Edison wasn't happy. He wanted a light bulb that could last much longer. So, his team did thousands of more tests.
Finally, they found that a material from bamboo could make light for a thousand hours.
Now, people all around the world could use the light bulb.
