In this sense, the invention of the light bulb was a decades-long process of incremental changes to create a filament that can be manufactured reliably and extended beyond Edison and Maxim alone.

He hadn’t invented the light bulb—yet. Or, to put it more precisely, he had invented a light bulb, but he couldn’t keep it lit for more than a few minutes at a time.
