'Diet Coke' (sometimes known as 'Diet Coca-Cola') or 'Coca-Cola Light' (sometimes known as 'Coke Light') is a
sugar-free
soft drink produced and distributed by
The Coca-Cola Company. It was introduced in the
United States on July 9, 1982 as 'Diet Coca-Cola', and was the first new brand since 1886 to use the
Coca-Cola trademark. The product quickly overtook
Tab in sales.
Diet Coke was sweetened with
aspartame as soon as the sweetener became available in the
U.S.,
1983; however, to save money, this was originally in a blend with
saccharin. After
Diet Rite cola advertised its 100 percent use of aspartame, and the manufacturer of
NutraSweet (then,
G.D. Searle & Company) warned that the NutraSweet trademark would not be made available to a blend of sweeteners, Coca-Cola switched the formula to 100 percent NutraSweet, later switching back and doing without the NutraSweet trademark. Diet Coke from fountain dispensers still contains some saccharin (to extend shelf life).

In other countries, where
cyclamates were not banned, as they were in the U.S. and the
United Kingdom in
1970, Diet Coke or Coca-Cola Light may be sweetened with a blend containing
cyclamates,
aspartame, and
acesulfame potassium.
In
2005, under pressure from retailer Wal-Mart (which was impressed with the popularity of Splenda sweetener), the company released a new formulation called "Diet Coke sweetened with Splenda."
Sucralose and
acesulfame potassium replace aspartame in this version. Early sales reports for this version were not quite as strong as anticipated; however, Coca-Cola did little advertising for the brand, investing money and advertising in
Coca-Cola Zero instead. The introduction of the Splenda sweetened version of Diet Coke saw complaints to bottlers, as store shelves would often go with very little of the normal version of Diet Coke.
Diet Coke does not utilize a modified form of the Coca-Cola recipe but is instead an entirely different formula. The controversial
New Coke, introduced in
1985, used a version of the Diet Coke recipe that contained
high fructose corn syrup and had a slightly different balance of ingredients. In 2004 Coca-Cola introduced
Coca-Cola C2, which it claims tastes much closer to Coca-Cola but contains half the
carbohydrates. In 2006, The Coca-Cola Co. introduced
Coca-Cola Zero, a sugar-free variation of regular
Coca-Cola.

When
Tab was released in
1963, the
Coca-Cola Company refused to use the Coca-Cola brandname, fearing that its flagship brand might suffer by being used on another product, the long-term viability of which was uncertain. (Ironically, Tab is still available today, even though vastly outsold by Diet Coke.) Its rival
Pepsi had no such qualms, and after the long-term success of its sugar-free brand
Diet Pepsi, launched in
1964, became clear, Coca-Cola decided to launch a new sugar-free brand under the Coca-Cola name to compete with Diet Pepsi. With the well-known name, it could be marketed more extensively than the more anonymously dubbed Tab.
Diet Coke and Diet Pepsi have capitalized on the markets of people who require low sugar regimens, such as
diabetics and people with other health conditions, athletes, and people who want to lose weight. In the UK, a 330 ml can of Diet Coke contains around 1.3 Calories (5 kilojoules) compared to 142 Calories (595 kJ) for a regular can of Coca-Cola.
Diet Coke is currently celebrating its 25th Anniversary.

Debate over health issues
The most commonly distributed version of Diet Coke (and majority of beverages using artificial sweeteners) relies on
Aspartame, which has been blamed by some scientists and medical professionals for possibly causing serious illnesses (such as cancer, brain tumors, brain lesions, and lymphoma) when consumed in large quantities
[2][3]. One of the chemicals produced by aspartame after ingestion is
methanol, which is also used in
antifreeze.

It should be noted that Coca-Cola has now released Diet Coke sweetened with
sucralose (also known as Splenda), although it is not as common. See also
soft drink controversy.
An article published in ''
The Independent'' on
May 27 2007 highlights the dangers of
sodium benzoate in soft drinks. According to the article, the sodium benzoate combines with the
citric acid in the drink to form
benzene, a known carcinogen. Also, the sodium benzoate was found to break down mitochondrial DNA in living yeast cells.
[5]
Concerning the Aspartame - large quantities means over 30 cans a day for the rest of your life.
[2]
Concerning the combination of sodium benzoate and citric acid, TCCC has reformulated its products so that the risk of forming carcinogens insie of soft drinks is eliminated.

Diet Coke and Mentos eruption - It is possible to cause a sudden high-pressure release of carbon dioxide by inserting multiple
Mentos into a container of Diet Coke. ''
Mythbusters'' found this is caused because of
nucleation as well as certain catalysts in the Diet Coke and Mentos themselves. The phenomenon is described in some detail by the General Chemistry Online! FAQ, which also attributes it to nucleation.
