Suddenly, the relationship changed when Land approached Kodak in 1968 about working with Polaroid on its latest, and most important development – an instant system featuring a film unit that could be ejected from the camera following exposure, could develop in the light, and would require no further physical manipulation: no peeling apart, no timing, no coating of the print for stabilization. By the mid-60s, Polaroid had become Kodak's second largest corporate customer, trailing only the tobacco companies for whom Kodak manufactured plastic cylinders for use in cigarette filters. When the first Polaroid one-step photography system was introduced in 1948, it was Kodak that manufactured the negatives, a function it performed for every film Polaroid introduced thereafter, including its first color film, Polacolor, released in 1963. In 1943, when Land launched an experimental program to develop a photographic system that could deliver an image in minutes without having to send the film to a laboratory for processing, it was his colleagues at Kodak that provided the necessary photographic chemicals, despite having no idea what Land was up to. In 1934, Kodak was the first customer for Edwin Land’s plastic polarizer sheet, an invention the Harvard dropout and Polaroid founder had made at the age of nineteen.
