The first record of the phrase"pizza" was approximately 997AD in southern Italy. It had been frequently produced in Naples and generally comprised tomato-based sauces, cheese, and fish.
But it wasn't till 1889 that if a chef in Naples called Queen Margherita (then called it"Margherita's Pizza"), that pizza was well approved. Pizza is one of the food items that are eaten in almost all nations. Pizza is the best food item to serve in weddings, business lunches, dinners, cocktail receptions, etc.
However, after being sampled by means of a queen, everybody wanted to check it out, and it turned into a tourist attraction. But it received the largest increase in popularity in the USA in 1940 when soldiers returning from World War II praised bringing back pizza home together. After the soldiers found the pizza, local bakers could barely keep up with the need for this. Even Dwight D. Eisenhower voiced his admiration for the dish.
Now's pizza"sector" started in 1958 with the arrival of Pizza Hut in Wichita, Kansas. Pizzerias became remarkably well known in the 50s and 60s and automobiles would run for miles to find pizza. With rising popularity, the pizza series was born. And that is the reason globalization of pizza has happened.
Nowadays you will find 6,000 Pizza Hut restaurants in the USA and over 5,600 store places in 94 other states and areas around the globe.
