What unifies all these products is the fact that they are mass produced. If you want to sell a pizza to everyone in America and you want them all to taste the same, you start to value consistency in your inputs.

I love to get pizza from some of the smaller pizzerias near me occasionally. I don't love that the cheese breaks sometimes, leaving me with a watery, ricotta-like mess on top of my pizza. I don't love that the crust is sometimes too thin and gets soggy or tears, or that the crust is occasionally burned in spots. This doesn't happen with Pizza Hut. Whatever else, they're consistent.

Personally, I also think that the cheese on a Pizza Hut pizza is just fine. If you're buying Pizza Hut or Papa John's, you're not looking for an old-world artisan experience. I don't want buffalo mozzarella on a delivery pizza.
