When my mother was growing up, she lived in Ohio. This would be in the 40's and early 50's... Her dad was Italian, his family came from Italy when he was pretty young. Anyhow, they liked pizza but if anyone came to their house they had to hide it because people made fun of them for eating 'tomato bread'. Mom was about 12 when the first pizzaria was opened in their area. Now you look at the frozen food section in a grocery store and there is a huge section with frozen pizzas. Could you imagine having to hide your pizza so that nobody will make fun of you for eating it?
