Tracing the history of pizza back to its earliest roots is virtually impossible, since ancient people often used bread as a plate and therefore probably ate something similar to the modern pizza.
But when did the pizza pie we know and love come out of the oven, and how did that flat “plate” of dough covered in cheese and toppings become the single most popular food in the world?
The PBS Idea Channel's Mike Rugnetta serves up the sizzling history of the pizza one slice of info at a time, and after your brain eats up all eight slices you'll feel full...of knowledge about the pie that conquered the world!
