I also remember and old retired man who lived at a nursing home in my town. He was old and forgotten by his family, but he was still healthy and energetic and we would see him walking all over town gathering up empty cola bottles to raise a little spending money. Later I found out that he gave that money to fellow residents at his nursing home. We called him Coke Bottle Joe. Everyone liked him. I hope he wound up in a special place, if such exist, as he certainly deserved to.

I think they would have switched to plastic bottles sooner but they had to find a plastic that could hold the pressure of the carbonation. At about the same time (mid 70's) they switched from tin to Aluminum cans for soda pop too. They had pop top openings like beer before that as well unlike the flip top opener that they have now. My dad put a glass bottle of Pepsi in the freezer (to get cold) and forgot it once. Naturally the bottle shattered since ice takes up more space than liquid and we were cleaning bits of frozen Pepsi out of the freezer for a long time after that. Film stock changed in the 70's as well. You can see that from how older 3 color Technicolor films from the 50's (like "The Robe" ) kept their colors over decades but movies like "The Godfather" were turning yellow after just a decade in the can. The two color process may have been cheaper but the film stock wasn't as long lasting in terms of keeping its colors bright. That's why a number of DVD's are 'digitally restored' I think. They had to restore the proper colors to the prints.
