Pizza is certainly one of the world’s favorite foods. But where does pizza come from? And who made the first one? In fact, people have been making pizza for a very long time. People in the Stone Age learned to cook dough, and then began covering it with various other foods herbs and spices. They had developed the world's first pizza. In the 19th century, cooks in Naples, Italy, began to put tomatoes on baking dough. The flat bread soon became popular among poor people all over Naples. In 1830, cooks in Naples took another big step in pizza history — they opened the world’s first pizza restaurant. Today, up to five billion pizzas are served every year around the world.
