Edwin H. Land, who founded the Polaroid Corporation, developed the first instant camera during World War II. Once the war was over and the economy improved and new industries flourished; one was instant photography. The first Polaroid Camera came out in 1948 but required the user to pull out the print, burst a pod of chemicals, and peel away the top layer. At first, prints were only available in sepia tone, but by 1950 black and white prints were available. Over the years and as technology progressed, prints would develop within a minute. In 1963, peel-apart color prints came along, but by 1972 they were non-peel-apart. 1977 was the height of popularity for instant photography and Polaroid held two thirds of the instant camera market. Sales began to decrease in 1979 when other technology such as 35 mm cameras became smaller and cheaper.
