Kodak gets picked on unfairly I think. When you look at the revenue streams before digital photography took off, you can see that Kodak had their fingers in every part of it - cameras, film, processing, printing. They made money every time you took a picture. There's simply no revenue stream in digital that's big enough to replace that. It's impossible to shrink a company by 90% gracefully.
Eastman, which was spun out of Kodak in 1994, is doing quite well. Demand for resins, plastic sheets and intermediates to make plastics products hasn't dropped. Kodak had no idea what their core product was going to be, and bulk chemicals would have been a good bet.
