I remember 8 of them. I'm probably on the "younger" side here - most of them I remember from the time I spent at my Grandma's house during the summers growing up.
2 of them - party line and newsreels before movies I know of but never experienced myself but my obviously my parents did. We did have a small town theater where I grew up that actually had an intermission! that's when we'd go get our candy and soda. LOL
