The Kodak Instamatic was a brand of instamatic cameras designed by Kodak and introduced to the market in 1963. The term instamatic refers to the film loading process, which is quite simply to insert the film cartridge into the camera and it is ready to shoot. Even amateur photographers found it very easy to load and unload conventional film in this “instant” manner.
