If it wasn't for the spread of pizzarias in the Italian-American community in the EARLY part of the 20th century and the rise in popularity of pizza outside that community after WWII, pizza would still be a virtually unknown, regionaly Italian specialty. Thus, the fact that pizza is so popular outside Naples is not because of Naples or Italians in Italy but because of Americans. Joes Pizza is family owned that has been in business since 1984.
