After improving upon the telephone, Edison created the phonograph, his favorite and most lucrative invention. Although Edison did not actually invent the light bulb, he did create an electric lighting system which led to its widespread use.
近三十岁时，爱迪生盖了一座“发明工厂”，可让他和他的同事专心致力于发明工作。在改进了电话功能后，爱迪生又发明了留声机，这是他喜爱的而且最能赚钱的一项发明。虽然爱迪生实际上并没有发明灯泡，但他的确发明了电灯照明系统，这导致了灯泡的广泛使用。
