This invention was a technological breakthrough at this time period because now the people could harness and use electricity now at the flip of a switch. Edison finally released the light bulb on Oct. 14, 1878 after he got the patent (Brigson). Later in Edison's life he also made the electric utility system, for the use of typewriters, light bulbs, phonograph, motion picture, and street lights.

Second, he made it cheaper for the middle class not just for the wealthy from $9 to $4.50 (Bane). Third, he made it more eco friendly from burning 25 kilowatts to just 10 kilowatts. The light bulb had made an impact culturally and economically bringing our country great
