Don't forget papier-mache!Newspaper is something that meant a lot to us old folks. Many people subscribed when they got new puppies so they didn't have to buy expensive puppy pads. They were good for lining birdcages and sopping up spills, also for when you cut your hair, or the kids wanted to draw on something and didn't have paper and you wouldn't let them draw on the walls. Some people actually read them.
I think Purina bought them all and now turns them into kitty litter.
