Polaroid has been in Chapter 11 about as long as I can remember. They are doing some coventures and I think they will be around for a while. People have been counting them out since about 1990 but they seem to stay around.
I never understood why Polaroid didn't jump into digital in some big way - it would seem a natural evolution of instant pictures. Maybe they didn't have money by the time digital took over. If I were wanting to produce a digital camera, I'd talk seriously to Polaroid about licensing the name.
