Exactly! General Electric was very much the Apple of the 19th century. Edison's genius was recognizing that he had to create demand for his product. It was not the case of "build it and they will come" - not even with the light bulb! Not only that, but Edison made the light bulb economically viable for everyday use. That's not a small feat! In a similar vein we all know Ford didn't invent the automobile, he was able to mass produce the automobile and make it affordable for everyone. We really need to distinguish between invention and mass production and scaling. Every country likes to claim the former, it was the United States that was really good at the latter - especially from the late 19th to mid 20th centuries.
