Motion pictures: Edison contributed significantly to the early days of motion pictures by inventing the Kinetoscope, a motion picture viewer, and the Kinetograph, a motion picture camera.
Phonograph: The phonograph, which records and reproduces sounds, was invented by Edison. It served as a forerunner to modern audio recording and playback technologies.
X-ray usage in medical imaging: Edison had a role in the early exploration of X-ray technology and helped create one of the first fluoroscopes, a device used in medical diagnostics.
Infrastructure development: Edison played a significant role in setting up the electrical distribution systems known as "central stations," which distributed electricity from a centralized power source to consumers and enterprises.
Mass production techniques: One of Edison's achievements was the concept of mass production, exemplified by his development of the Menlo Park facility, which brought a cross-disciplinary approach to innovation and development.
Electric car development: Edison's influence extended to the automotive industry, particularly electric cars. He was instrumental in the creation of an early electric car prototype.
