PBS Idea Channel host, Mike Rugnetta, takes an in-depth look at the delicious history, evolution, and cultural impact of pizza.
"Pizza might be an Italian invention, but it is a worldwide phenomenon. Pizza has managed to evolve from a simple, rustic food item to something much more impactful. For many it is a comfort food, something that can cause an actual psychological reaction. And it is also a product, heavily branded and resold on t-shirts, hats, socks, etc."[PBS Idea Channel]
