As you might be aware, Eastman Kodak invented the digital camera but ultimately failed to recognize the consumer demand for them and became an also-ran in a market they created. Jim McGarvey worked there and in 1987 was given the task of building a prototype camera using Kodak’s recently announced megapixel CCD for the government. It was called the Electro-Optic Camera, was built using a Canon camera body and was the first DSLR.
Kodak began building the DCS line of professional cameras in 1991 and was alone in the market until Nikon introduced their D1 in 1999. Canon eventually followed suit. By the early 2000s Kodak, which had never turned a profit with the DCS line, abandoned the professional camera market.
