Editing Pepsi One (section)

==History==
On June 30, 1998, the artificial sweetener [[acesulfame potassium]] (Ace-K) was approved for use by the [[Food and Drug Administration]]. PepsiCo responded within one hour, announcing the introduction of Pepsi One (which reached store shelves the following October). The original formulation was sweetened with [[aspartame]] and [[acesulfame potassium]]. This new variety was based upon an earlier product (sold in other countries) called [[Pepsi Max]], but it featured a formula and flavor profile developed specifically for the U.S. market.

The launch of Pepsi One included an advertising campaign featuring the slogan "just one calorie."  Subsequently, comedian [[Tom Green]] appeared as the spokesperson in a series of television advertisements that began airing in April 1999.<ref>{{cite web|title=Pepsi One's 'Tom Green' commercials begin new TV ad flight after being recut|url=http://adage.com/article/news/pepsi-s-tom-green-commercials-begin-tv-ad-flight-recut/24951/|website=AdAge|date=April 1999 |accessdate=15 March 2017|language=en}}</ref>

Before 2012, Pepsi One was the last Pepsi variant to include the old logo used from 2003 to 2008, while all the other Pepsi variants had been using the current logo used since late 2008; the only other Pepsi product not using the current logo was [[Pepsi-Cola Made with Real Sugar|Pepsi Throwback]], which intentionally used [[retro]] packaging. However, Pepsi One's logo was later modernized with the current logo to be in line with the other flavors.

On March 21, 2005, Pepsi-Cola North America announced that it would begin adding [[sucralose]] to a newly reformulated Pepsi ONE in order to create a full-flavor cola taste.<ref>{{cite web|title=Pepsi ONE Re-launches with SPLENDA(r) Brand Sweetener|url=https://www.bevnet.com/news/2005/03-21-2005-pepsi_one_splenda.asp|website=Bevnet|date=21 March 2005 |accessdate=4 April 2018|language=en}}</ref>

In January 2014, Consumer Reports magazine tested levels of the chemical [[4-methylimidazole]] (4-MeI){{snd}}a potential carcinogen{{snd}}in various beverages in the United States and found that Pepsi ONE was one of two drinks that contained the chemical in excess of 29 micrograms per can or bottle, with that being California Proposition 65's daily allowed amount for foods without a warning label.

In mid-2015, after its sister product [[Diet Pepsi]] had changed to using sucralose and Ace-K as sweeteners instead of aspartame, Pepsi One was discontinued. PepsiCo wrote on its website that "Pepsi ONE has been discontinued. We regularly evaluate our product portfolio to find efficiencies, and we have decided to remove Pepsi ONE from the marketplace. Pepsi ONE has very limited distribution and will be out of the marketplace by start of the year 2015, and in some markets product inventory has already been exhausted."
