BIG MAC ATTACK: The Big Mac was thought up in 1967 by Jim Delligatti, who owned a McDonald's store near Pittsburgh. The sandwich sold for 45 cents. Today, the burger costs about $2.75.
GLOBAL FLAVOR: Around the globe, the Big Mac's ingredients follow its catchy jingle: Two all-beef patties, special sauce, lettuce, cheese, pickles, onions on a sesame seed bun. A notable exemption is India, where the burger is called the Maharaja Mac and is made with chicken.
HEAVY-WEIGHT COMPETITION: The Big Mac spawned generations of bigger and bigger burgers. Wendy's offers a "Triple with Cheese," which has 980 calories and 59 grams of fat. Burger King has a 1,230 calorie Triple Whopper loaded with 82 grams of fat. Even McDonald's has a double-quarter pounder with cheese, which has 740 calories and 42 grams of fat.
