The world’s two largest pizza chains, Dominos and Pizza Hut, are constantly trying to come up with new ways to keep existing customers and attract new ones. While Dominos attract fans by using high-tech concepts like delivery robots, Pizza Hut focuses on making the delivery box more exciting. In 2015, they introduced a pizza box that could be transformed into a movie projector (放映机) and now, one that turns into a fully functioning DJ.
