By October 1879 Thomas Edison and his Menlo Park team had a lamp whose carbonized cotton-thread filament burned for fourteen and a half hours, and from 1879 he patented and commercialized the incandescent bulb. He was not the first to make one: William Sawyer, Albon Man and Joseph Swan all held earlier incandescent patents. What Edison delivered was the practical, long-lived lamp and, with it, the demand for central generation that called the power station into being.
