-->Inventii0n<--
For me the best invention of the histpry was the bulb. The bulb was invented by Thomas Edison (businessman and inventor), other inventors had also developed models taht worhed. The bulb is one of the inventions most used by people since its creation. It was developed on October 21, 1879 during a second industrial revolution. Before the inventio of bulb the only means of ilumination were fire, the candles and lamps, but all had problems, such as poor lighting or poor security, when Edison invented the bulb, solved all. The sale of the bulb by the company of Thomas Alva Edison was plagued by disputes with competitors.
