In 1883 the Edison & my United Electric Light Company was established. Known commonly as "Ediswan" the company sold lamps made with a cellulose filament that I had invented in 1881. Variations of the cellulose filament became an industry standard, except with the Edison Company. Edison continued using bamboo filaments until the 1892 merger that created General Electric -- and that company then shifted to cellulose.
