The take up of silver products would be larger if people knew that they are still produced and are easily available. I talk to surprisingly many people who are convinced that Kodachrome was the last film being produced in the world.
I think this is a good point. I'm sure we've all heard that film is no longer available from people that are not really avid photographers. I always tell them where to get film and processing if they're interested. More advertising would be good, but can the companies afford that?
Moma don't take my Kodachrome away!
Oops, Kodak just did!
For all practical purposes, they've taken Kodak away.
