Pizza, which originated in Italy. Is a fast food that is known and loved all around the world. How did it become so popular? Part of the reason is that tourists who went to Italy ate it there and loved it. When they returned to their countries, They looked for Italian restaurants that might have it. But much more significant in pizza becoming popular worldwide the fact that lots of American soldiers who were in Italy during World War II ate it there and then wanted it when they returned to the USA. This dramatic increase in the demand for pizza in the 1950s led to the development of special restaurants for pizza.
