In my childhood, B&W film was still easy to find; by about 1980 (at least around here), it had become something mostly found in shops frequented by pro photographers. Signs at the one-hour processing places said, no same-day for B&W. High-end digital cameras are going to take over, but of course there will be those who still use ‘em, just as there are antique cars, sailboats, and 25 year old computers being used by hobbyists (grin).
