Pizza has been around for hundreds of years. First conceived in Naples, Italy, it was improved with tomato sauce and became an American staple food. The competition between pizza parlors and other providers has reached a fever pitch, leading to competition over the "next big thing" in pizza, whether it's a better recipe, faster delivery, reduced labor costs, or the most outrageous advertising gimmick. Weird History Food abandons trying to tell the complete history of pizza in order to bring us the most innovative and bizarre recent pizza schemes, all in the name of making us crave a hot and tasty slice of pizza. They weren't all successful, or even edible, but they do show some thinking outside the pizza box.
