Self Inflicted
Kodak had plenty of chances. They saw which way the wind was blowing like everyone else. They totally failed with their research and development to produce a decent digital camera or compete with digital memory (once called "digital film"!). If they had spent the money on R & D, they might be with us today. Most likely the money for R & D was strangled for short-term gain and profit. Now Kodak is gone.
I do find it sad that a company known for inventing so many things couldn't invent a product that allowed it to compete. Chalk up another death for the beancounters.
