Pizza, one of my favorite foods, but i dont know much about it. Did pizza actually originate in italy or was it popularized there?
I like it too, I make it at home using yeasted flatbread  topped with tomato sauce and cheese and baked in an oven.
Nice. I've never made my own pizza. Are there different/special categories or styles of pizza?
No all i know is that Pizza is Pizza, only difference is sometimes you can get your own special flavor by  adding vegetables, meats, and condiments, and can be made without cheese. The key word here is to get creative so as to have a different taste 
Yeah cool. When was the first pizza developed or baked?
Good question, the history date as far back as 10th century
Wow pizza is very very old. Can you told me a weird fact about pizza people barely know? A lot of people never talk about pizza unless they are talking about toppings haha.
I actually have not had a bad moment with Pizza, but I know that modern pizza was  invented in Naples and since then different variants  of Pizza with nice flavors have flooded the market
Oh naples that is interesting. What country loves pizza the most if i may ask?
It's Italy because historians traced Latin manuscript from the Southern Italy town of Gaeta in Lazio, on the border with Campania
