Edison demonstrated his incandescent light bulb for the first time on 31December 1879, in Menlo Park, New Jersey, but this demonstration was for a group of his associates.
The Menlo Park demonstration marked a crucial moment in the history of electric lighting. Edison's incandescent light bulb was a groundbreaking invention that eventually revolutionized the way people lit their homes and workplaces.
On 04 September 1882 Edison's Pearl Street Electric Power Station in New York City began operating, providing electrical power for customers in a square-mile area. This event is often considered the first public use of Edison's incandescent lighting system, marking the beginning of the widespread adoption of electric lighting.
