I do really enjoy that traditional itallian dish made of flatbread topped with tomato sauce and cheese!
Where did pizza originate? Was it in Italy?
Well the term pizza was recorded in the 10th century in a Southern Italy town of Gaeta. 
Gaeta? I'm not familiar with that location. What exactly is a Neopolitan style pizza?
Well I can tell you that in 2009 it was registered with EU as a Traditional Specialty Guaranteed Dish. 
That must be a special pie! lol When did pizza become popular in the United States?
called pizzettas.

Modern pizza was invented in Naples, and the dish and its variants have since become popular in many countries. It has become one of the most popular foods in the world and a common fast food item in Europe and North America, available at pizzerias (restaurants specializing in pizza), restaurants offering Mediterranean cuisine, and via pizza delivery
mozzarella di bufala Campana, made with milk from water buffalo raised in the marshlands of Campania and Lazio. This mozzarella is protected with its own European protected designation of origin.
