The Quarter Pounder is a hamburger sold by international fast food chain McDonald's, so named for containing a patty with a precooked weight of four ounces (113.4 g), or one quarter of a pound. It was introduced in 1971. In 2013, the Quarter Pounder was expanded to represent a whole line of hamburgers that replaced the company's discontinued Angus hamburger. In 2015, McDonald's increased the precooked weight to 4.25 oz (120 g).

A&W Restaurants, Inc. is an American fast food restaurant chain distinguished by its burgers, draft root beer and root beer floats. The oldest extant restaurant chain in the United States, A&W's origins date back to 1919 when Roy W. Allen set up a roadside drink stand to offer a new thick and creamy drink, root beer, at a parade honoring returning World War I veterans in Lodi, California. Allen's employee Frank Wright partnered with him in 1922 and they founded their first restaurant in Sacramento, California, in 1923. The company name was taken from the initials of their last names – Allen and Wright. The company became famous in the United States for its "frosty mugs" – the mugs were kept in a freezer and filled with A&W Root Beer just before being served to customers.
