Kodak, originally known for still photography, transformed culture forever and set a precedent that would go on to last for over a generation. In 1891, Kodak released a transparent roll film, which inventor Thomas Edison used to develop the first motion picture camera.
Technical limitations often dictate a medium. Kodak’s film was created in the 4:3 aspect ratio. The decision by Edison to use Kodak’s film locked filmmakers and audiences into the 4:3 aspect ratio for over a century. Today, Instagram, with its release of IGTV, is following in Edison’s footsteps and solidifying a place in history for vertical video.
