Science and technology in the United States finish. For example, the British engineer Joseph Swan built an incandescent electric lamp in 1860, almost 20 years before Edison. But Edison's light bulbs lasted much longer than Swan's, and they could be turned on and off individually, while Swan's bulbs could be used only in a system where several lights were turned on or off at the same time. Edison followed up his improvement of the light bulb with the development of electrical generating systems. Within 30 years, his inventions had introduced electric lighting into millions of homes. Another landmark application of scientific ideas to practical uses was the
Technology brokering class behind the Sam Adams brand. The Light Bulb On December 31, 1879, Edison first displayed his most popular invention. It was the first "practical incandescent, electric lamp. This is a perfect example of Thomas Edison leveraging technology brokering. Edison was not the first person to invent electric light. J.W. Starr filed a patent for an incandescent bulb in 1854. That was 30 years before Edison began working on the light bulb we know today. When Edison first started testing incandescent lamps, the arc light was being used for lighting streets and also for various other applications. When Edison began
