Whose work led to the widespread use of electic or incadescent lights?

While many people contributed to the development of electric and incandescent lighting, Thomas Edison is widely credited with its widespread use.

Here's why:

* Practical Incandescent Bulb: While others had developed incandescent bulbs before, Edison's bulb was the first to be both practical and commercially viable. It lasted longer and was more efficient than previous designs.

* Complete System: Edison didn't just invent the bulb. He developed a complete system for generating, distributing, and using electricity, including power plants, wiring, and sockets. This made electric lighting accessible to the public.

* Marketing and Promotion: Edison was a skilled marketer and promoter. He understood the importance of public perception and made electric lighting desirable and affordable for the average person.

While Edison didn't invent the first incandescent bulb, his work led to its widespread adoption, making it a cornerstone of modern life.
