You are right. But not only the lack of demand is a problem. Cost is a problem. Kodak is too big for the market. Market is smaller than in the past, BUT THERE IS AND STILL WILL BE THE MARKET. I am 100% sure that kodachrome and ektachrome would be profitable, if costs were fitted into smaller company.
You owe yourself a tour through the recent Kodak threads for an idea of the economics of film production.
