One of my favorite foods is pizza. Pizza as we know it was invented in Naples, Italy and it has become popular worldwide.
I'm eating pizza right now!  I had no idea which part of Italy it was from.
Lucky You! The name pizza was actually found in a manuscript in Southern Italy dating from the 10th century. That's an ancient lunch you're having!
I thought I had heard before that the modern style of pizza was developed in the United States, and that the Italian version is a lot different.
It depends which type of pizza you mean. New York style pizza is more neapolitan in design, whereas e.g. deep dish Chicago pizza is not at all similar.
I don't even consider Chicago style as pizza.  That's more of a tomato cake.  You can't even hold a slice without making a mess.
Chicago-style pizza
Chicago-style pizza is pizza prepared according to several different styles developed in Chicago. The most famous is deep-dish pizza. The pan in which it is baked gives the pizza its characteristically high edge which provides ample space for large amounts of cheese and a chunky tomato sauce. Chicago-style pizza may be prepared in deep-dish style and as a stuffed pizza.

According to Tim Samuelson, Chicago's official cultural historian, there is not enough documentation
called pizzettas.
The term "pizza" was first recorded in the 10th century in a Latin manuscript from the Southern Italian town of Gaeta in Lazio, on the border with Campania. 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
