In the United States during the 20th century, there have been numerous celebrations marking the centenary of the burger. Two locations in particular organized high-profile events to celebrate 100 years of the hamburger. One was held in Athens, Texas, in November 2006, in honor of Fletcher Davis. In a resolution made by the state of Texas, it was established that Athens is the "Original Home of Hamburger". However, in August 2007, the state of Wisconsin made the same claim on behalf of the town of Seymour, the home of Charlie Nagreen who also claimed to be the creator of the hamburger. These two decisions have split the honor of creating the hamburger between these two American cities. The town of Seymour continues to annually celebrate a "Burger Fest" on the first Saturday of each August. Nutritional controversies Since the latter part of the 20th century, the burger has undergone several controversies regarding its nutritional values.

AESAN works to prevent the growth of the incidence of obesity in all people, particularly children. More generally, dietitians are beginning to see that the consumption of foods high in calories can cause excessive appetite. In response to this message, many restaurant chains have reduced the calories in their burgers since the beginning of the 20th century. The late 20th century witnessed a lawsuit brought by McDonald's against two environmental activists, Helen Steel and David Morris, that was colloquially known as the McLibel case. McDonald's took action following the publication of a pamphlet by Steel and Morris that was entitled What’s wrong with McDonald’s: Everything they don’t want you to know, which was subsequently developed into a documentary called McLibel. Media In 2004, Morgan Spurlock addressed the obsessive consumption of hamburgers by some Americans by directing and starring in the documentary film Super Size Me. In the film, he himself eats only McDonald's food for an entire month and documents how
