According to Palmer, he was in the habit of drinking iced tea with lemonade at home, and in 1960 at the US Open at the Cherry Hills Country Club in Denver, Colorado, he ordered the drink at the bar. A woman sitting nearby overheard him, and ordered "that Palmer drink", thus giving the beverage its name. In 2012 an ESPN 30 for 30 Shorts documentary was produced on the drink, featuring Palmer, beverage experts, a group of PGA golfers and comedian Will Arnett discussing the drink's history and popularity. In the film, Palmer attributes the spreading of the drink's name to a similar incident in which a woman copied his ordering the drink at lunch while working on a golf course in Palm Springs, California.
The drink is also referred to as a "Half & Half" in many parts of the United States, especially the South.
A John Daly, named after professional golfer John Daly, is a mixed drink made by adding vodka to an Arnold Palmer. Another hard variant, the "Arnold Palmer Hard," replaces the vodka with a malt beverage.
Monster Energy produces a tea/lemonade product that adds stimulants and electrolytes to create an energy drink. The beverage is marketed under its "Monster Rehab" brand.
The drink was sold under the Arnold Palmer name by Innovative Flavors since 2001, with Palmer's picture and signature on the bottle. Since the mid-2000s, Arizona Beverage Company has handled distribution of the beverage. Arizona sells Arnold Palmer half-and-half in 11.5 and 23 ounce cans, 20, 34, and 42 ounce bottles, and 64 ounce and gallon jugs. Lemonade combined with iced tea is also sold without the Arnold Palmer name by other companies, such as Lipton Brisk, HONEST tea, Country Time,Sweet Leaf,XINGtea,Snapple, and Peace Tea (as Caddyshack).
