There are quite a few articles online that go into some detail about it. Just search for "Kodak Clay Christensen", or something similar. Here's one: http://www.economist.com/node/21542796

    Another reason why Kodak was slow to change was that its
    executives “suffered from a mentality of perfect products,
    rather than the high-tech mindset of make it, launch it,
    fix it...”
    
    Bad luck played a role, too. Kodak thought that the thousands
    of chemicals its researchers had created for use in film
    might instead be turned into drugs. But its pharmaceutical
    operations fizzled, and were sold in the 1990s.

On a related note, I just purchased a 10 pack of Kodak Portra 400 4x5" sheet film last night. I normally shoot Kodak's Tri-X and 5222 cine film, or Fuji's Acros 100, but thought it'd be fun to get into large format color photography on occasion.
