In 1958, Frank and Dan Carney opened the first Pizza Hut in Wichita, Kansas. They sold two pizza sizes and offered two toppings: pepperoni or sausage. The business grew into six restaurants within a year. Then the Carneys began franchising and the company grew even larger.
By the mid-1960s, half of the revenue came from takeout orders. In 1965, Pizza Hut issued its first television commercial with this market in mind. It shows a man ordering pizza over his home phone, then driving to pick it up. He's using a tiny Junior Central brand Ford Mustang go-kart.
One surprise for me: the pizza doesn't come in boxes, but in paper bags.
