Thus was born the phonograph. But it was not all victories, many of its investigations ended in failure, but always kept trying. In 1879, the challenge to achieve and maintain a light bulb long time.
Edison found carbonized bamboo filament and displaying his pragmatism, set up a workshop for manufacturing the same bulbs, and began selling at 40 cents, although it will cost more than a dollar.
This increased demand and managed to produce large-scale, reduced costs to 37 cents: the business began to go smoothly. His fame spread throughout the world. After the death of his first wife visited Europe and was well received.
