I love eating pizza, what of you
I love it. Its the only food I don't ever tire of even if it is a traditional Italian dish
You mean you like eating Italian pizza
Well pizza is from Italy.  The phrase Pizza was first recorded in the 10th century, in a Latin manuscript from Southern Italy 
That was truly an ancient cuisine
The actual pizza that you and I consume today actually was invented in Naples and its variants have become popular to this day.
Is Naples in Italy?
Yes. Actually in 2009 upon the request of Italy, the Neapolitan pizza was registered with the European Union as a Traditional Speciality Guaranteed dish
When was the first pizza franchise recorded ?
Can't really place it  but I would say between 1950's and 1960's. Pizza has become one of the most popular foods in the world
