Coca-Cola is a carbonated soft drink sold in the stores, restaurants, and vending machines of more than 200 countries. It is produced by The Coca-Cola Company of Atlanta, Georgia, and is often referred to simply as Coke (a registered trademark of The Coca-Cola Company in the United States since March 27, 1944). Originally intended as a patent medicine when it was invented in the late 19th century by John Pemberton, Coca-Cola was bought out by businessman Asa Griggs Candler, whose marketing tactics led Coke to its dominance of the world soft-drink market throughout the 20th century.
The company produces concentrate, which is then sold to licensed Coca-Cola bottlers throughout the world. The bottlers, who hold territorially exclusive contracts with the company, produce finished product in cans and bottles from the concentrate in combination with filtered water and sweeteners. The bottlers then sell, distribute and merchandise Coca-Cola to retail stores and vending machines. Such bottlers include Coca-Cola Enterprises, which is the largest single Coca-Cola bottler in North America and western Europe. The Coca-Cola Company also sells concentrate for soda fountains to major restaurants and food service distributors.
The Coca-Cola Company has, on occasion, introduced other cola drinks under the Coke brand name. The most common of these is Diet Coke, with others including Caffeine-Free Coca-Cola, Diet Coke Caffeine-Free, Coca-Cola Cherry, Coca-Cola Zero, Coca-Cola Vanilla, and special editions with lemon, lime or coffee.
In response to consumer insistence on a more natural product, the company is in the process of phasing out E211, or sodium benzoate, the controversial additive used in Diet Coke and linked to DNA damage in yeast cells and hyperactivity in children. The company has stated that it plans to remove E211 from its other products, including Sprite and Oasis, as soon as a satisfactory alternative is found.
On April 23, 1985, Coca-Cola, amid much publicity, attempted to change the formula of the drink with "New Coke". Follow-up taste tests revealed that most consumers preferred the taste of New Coke to both Coke and Pepsi, but Coca-Cola management was unprepared for the public's nostalgia for the old drink, leading to a backlash. The company gave in to protests and returned to a variation of the old formula, under the name Coca-Cola Classic on July 10, 1985.
On February 7, 2005, the Coca-Cola Company announced that in the second quarter of 2005 they planned to launch a Diet Coke product sweetened with the artificial sweetener sucralose, the same sweetener currently used in Pepsi One. On March 21, 2005, it announced another diet product, Coca-Cola Zero, sweetened partly with a blend of aspartame and acesulfame potassium. In 2007, Coca-Cola began to sell a new "healthy soda": Diet Coke with vitamins B6, B12, magnesium, niacin, and zinc, marketed as "Diet Coke Plus."
On July 5, 2005, it was revealed that Coca-Cola would resume operations in Iraq for the first time since the Arab League boycotted the company in 1968.
In April 2007, in Canada, the name "Coca-Cola Classic" was changed back to "Coca-Cola." The word "Classic" was truncated because "New Coke" was no longer in production, eliminating the need to differentiate between the two. The formula remained unchanged.
In January 2009, Coca-Cola stopped printing the word "Classic" on the labels of 16-ounce bottles sold in parts of the southeastern United States. The change is part of a larger strategy to rejuvenate the product's image.
In November 2009, due to a dispute over wholesale prices of Coca-Cola products, Costco stopped restocking its shelves with Coke and Diet Coke.
