After World War II, pizza took off in the US

Pizzerias opened in cities throughout the 1920s and '30s, especially those with large Italian immigrant populations, but the cuisine didn't take off nationally until after World War II. Some credit that with American soldiers' exposure to the food while stationed in Italy; others point to the invention of the mass-produced gas-fired ovens, which made opening a pizzeria considerably easier.
