'''Pepsi One'''<ref>{{Cite web|url=https://trademarks.justia.com/755/07/pepsi-one-75507831.html|title=PEPSI ONE - Trademark Details|website=[[Justia]] Trademarks|access-date=February 24, 2026}}</ref> was a sugar-free [[cola]], marketed by [[PepsiCo]] in the United States from 1998 to 2015 as an alternative to regular [[Pepsi]] and [[Diet Pepsi]]. It was also corporately styled '''PEPSI ONE''', so named because it contains one [[calorie]] per eight-[[fluid ounce]] [230 ml] serving.

==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.<ref>{{Cite news |date=1998-07-01 |title=New Pepsi Drink to Use Special Sweetener (Published 1998) |url=https://www.nytimes.com/1998/07/01/business/new-pepsi-drink-to-use-special-sweetener.html |access-date=2025-09-10 |language=en}}</ref> The original formulation was sweetened with [[aspartame]] and [[acesulfame potassium]].<ref>{{Cite news |date=1998-11-05 |title=THE MEDIA BUSINESS: ADVERTISING; Pepsi-Cola North America hopes its overhaul will sweeten relations with stores and consumers.

Before the launch of Pepsi One in 1998, PepsiCo also marketed [[Diet Pepsi]] as having one calorie per serving from that product's launch in 1964 until 1991.{{Citation needed|date=September 2025}}

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=https://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>

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 2015, after its sister product [[Diet Pepsi]] had changed to using sucralose and Ace-K as sweeteners instead of aspartame, Pepsi One was discontinued.<ref>{{Cite web |last=Wong |first=Venessa |date=2015-08-12 |title=Diet Pepsi Ditched Aspartame, Is Now Sweetened With Sucralose.
