McDonald’s started serving pizza and intended to compete with chains like Domino’s. The pizza took far longer to make, and consumers just weren’t willing to wait for food that was supposed to be fast. There was also the McPizza, which resembled Hot Pockets and failed miserably. Competition in the pizza industry was intense, and McDonald’s couldn’t stand up to Pizza Hut or Domino’s. People just weren’t interested in having pizza at McDonald’s when they just wanted burgers.
