In which year was the first incandescent bulb invented?

The invention of the first practical incandescent light bulb is attributed to Thomas Edison, who succeeded in developing a commercially viable design in 1879. This year is significant because it marks the point when Edison's bulb became widely recognized and used, leading to the widespread adoption of electric lighting. Prior to this, several inventors had experimented with incandescent bulbs, but they were not practical for everyday use. Edison's improvements, including the filament material and bulb design, resulted in a product that could last longer and be produced on a larger scale, thus revolutionizing lighting and paving the way for electric illumination in homes and businesses.
