阅读理解。 McDonald's Corporation (NYSE: MCD) is the world's largest chain of hamburger fast food restaurants, serving nearly 47 million customers daily 1 Brands (KFC, Taco Bell and others) and sandwich chain Subway. In addition to its signature restaurant chain, McDonald's Corporation held a minority interest in Pret A Manger until 2008, and owned the Chipotle Mexican Grill until 2006 and the restaurant chain Boston Market until 2007. 2 The corporations' revenues come from the rent, royalties and fees paid by the franchisees, as well as sales in company-operated restaurants. 3 In response to obesity trends in western nations and in the face of criticism over the healthiness of its products, the company has modified its menu to include such healthier alternatives as salads, wraps and fruit. The business began in 1940, with a restaurant opened by brothers Dick and Mac McDonald in San Bernardino, California. Their introduction of the'Speedee Service System' in 1948 established the principles of the modern fast-food restaurant. The original mascot of McDonald's was a man with a chef's hat on top of a hamburger shaped head whose name was 'Speedee.' Speedee was eventually replaced with Ronald McDonald in 1963. The first McDonald's restaurants opened in the United States, Canada, Costa Rica, Japan, the Netherlands, Germany, Australia, France, El Salvador and Sweden in order of openings. The present corporation dates its founding to the opening of a franchised restaurant by Ray Kroc, in Des Plaines, Illinois on April 15, 1955, the ninth McDonald's restaurant overall. 4 Kroc was also noted for aggressive business practices, compelling the McDonald brothers to leave the fast food industry.
