Often that was Western Union Telegraph Company, the industry leader, but just as often, it was one of Western Union's rivals. In , Edison moved his expanding operations to Menlo Park, New Jersey, and built an independent industrial research facility incorporating machine shops and laboratories.

Army to bring music to the troops overseas during World War I. While Edison was not the inventor of the first light bulb, he came up with the technology that helped bring it to the masses. After buying Woodward and Evans' patent and making improvements in his design, Edison was granted a patent for his own improved light bulb in He began to manufacture and market it for widespread use. In January , Edison set out to develop a company that would deliver the electricity to power and light the cities of the world.

In , the Pearl Street generating station provided volts of electrical power to 59 customers in lower Manhattan. In , Edison built an industrial research laboratory in West Orange, New Jersey, which served as the primary research laboratory for the Edison lighting companies. He spent most of his time there, supervising the development of lighting technology and power systems. He also perfected the phonograph, and developed the motion picture camera and the alkaline storage battery. Over the next few decades, Edison found his role as inventor transitioning to one as industrialist and business manager.
