What You'll Learn

Pepsi Zero Sugar's history
Pepsi Zero Sugar, formerly known as Pepsi Max and Diet Pepsi Max, is a zero-calorie, sugar-free, formerly ginseng-infused cola. It is sweetened with aspartame and acesulfame K and marketed by PepsiCo.
Diet Pepsi Max was introduced in the United States on June 1, 2007, and in Canada in March 2008. "Diet" was dropped from the name in early 2009, and the drink was then known as Pepsi Max until August 2016. On June 29, 2015, PepsiCo announced that Pepsi Max would be renamed Pepsi Zero Sugar in North America, while the drink retained the Pepsi Max name internationally.
Pepsi Zero Sugar has nearly twice the caffeine of Pepsi's other cola beverages. Before a recipe change in late 2022, it contained 69 milligrams of caffeine per 355 mL (12.5 imp fl oz), compared to 36 milligrams in Diet Pepsi. A new logo was introduced in 2020.
Pepsi Zero Sugar has been marketed as an "Invigorating Cola" in the energy drink market, with commercials portraying it as an alternative to Diet Pepsi. The drink has been advertised as a bolder, closer-to-original Pepsi alternative, with a deeper flavor and a longer-lasting sweetness.
In 2011, a commercial featuring Snoop Dogg aired around the time of Super Bowl XLV. In 2013, Pepsi Zero Sugar, then known as Pepsi Max, partnered with NASCAR Sprint Cup Series champion Jeff Gordon for a campaign called "Pepsi Max & Jeff Gordon Present: Test Drive."

Diet Pepsi's history
Pepsi Zero Sugar, formerly known as Diet Pepsi Max and Pepsi Max, is a zero-calorie, sugar-free cola drink. It was introduced in the United States on June 1, 2007, and in Canada in March 2008. The name "Diet" was dropped from the product in early 2009.
Diet Pepsi, on the other hand, has been around since the 1960s and was the first diet drink introduced by Pepsi. It uses aspartame as its sweetener, giving it a smoother, lighter profile with a slightly dry finish. It is popular among those who want a mellow drink or drink soda all day.
In the 1970s, health concerns arose over the artificial sweeteners cyclamates and saccharin, commonly used in diet sodas at the time. This led to the adoption of aspartame, a sweetener 200 times sweeter than regular sugar with no caloric content, making it the perfect substitute for diet drinks.
Pepsi Zero Sugar is a newer product, using a blend of aspartame and acesulfame potassium (also known as Ace-K) as sweeteners. It has more caffeine than Diet Pepsi and is marketed as a bolder, closer-to-original Pepsi alternative. It has a richer, more intense flavour and is often preferred by those who want more energy or miss the full-bodied flavour of regular soda.
Both drinks serve a similar purpose of providing a sugar-free, calorie-free alternative to regular Pepsi, but they have different formulas and cater to different taste preferences. While Diet Pepsi has a lighter, crisp finish, Pepsi Zero Sugar is bolder and has a deeper flavour, resembling regular Pepsi with a bit of extra kick.

Differences in ingredients
Pepsi Zero Sugar and Diet Pepsi are both sugar-free colas, but they have different formulas. Diet Pepsi has been around since the 1960s and uses aspartame as its sweetener, whereas Pepsi Zero Sugar is a newer product that uses a blend of aspartame and acesulfame potassium (also known as acesulfame K).
The ingredients in the two drinks are not listed in the same order. Aspartame is the third ingredient in Diet Pepsi and the fourth in Pepsi Zero Sugar. Diet Pepsi also contains the sweetener acesulfame potassium, which is not listed in Pepsi Zero Sugar. On the other hand, Pepsi Zero Sugar contains calcium disodium EDTA, a food additive used to preserve flavour, colour, and texture, which is absent from Diet Pepsi.
Both drinks contain carbonated water, caramel colour, phosphoric acid, potassium benzoate, caffeine, and citric acid. However, the caffeine content in the two drinks differs. Before a recipe change in late 2022, Pepsi Zero Sugar contained 69 milligrams of caffeine per 355 mL, while Diet Pepsi contained 36 milligrams. In January 2023, PepsiCo reduced the caffeine content in Pepsi Zero Sugar in the United States.

Marketing and advertising
Pepsi Zero Sugar, formerly known as Diet Pepsi Max and Pepsi Max, is a zero-calorie, sugar-free cola drink. It was introduced in North America in 2007 as Pepsi Max and was renamed Pepsi Zero Sugar in 2015. The drink is marketed as a bolder, closer-to-original Pepsi alternative with more caffeine and a blend of two artificial sweeteners, aspartame and acesulfame potassium (Ace-K).
The marketing and advertising campaigns for Pepsi Zero Sugar have been designed to highlight its unique selling points and differentiate it from its competitors, including Diet Pepsi and other zero-sugar cola drinks in the market.
One of the key strategies used in the marketing of Pepsi Zero Sugar is the emphasis on its bold and intense flavour. With its higher caffeine content and blend of artificial sweeteners, Pepsi Zero Sugar is positioned as a stronger and fuller-bodied option compared to Diet Pepsi, which has a lighter and smoother taste. The use of the word "Zero" in the name also helps to communicate the absence of sugar in the drink, which is a key selling point for health-conscious consumers.
To create a buzz around the product and engage potential consumers, PepsiCo has employed creative advertising campaigns for Pepsi Zero Sugar. One notable campaign featured a pair of delivery drivers from Coca-Cola and Pepsi, who formed a tentative friendship despite their rivalry. The ad played on the idea of competitors tasting each other's products, with the Coca-Cola driver refusing to return the superior Pepsi product. This ad campaign, featuring the song "Why Can't We Be Friends?" by War, created a humorous and memorable narrative that helped to promote Pepsi Zero Sugar.
Celebrity endorsements have also played a role in the marketing of Pepsi Zero Sugar. In 2011, rapper Snoop Dogg was featured in an ad campaign around the time of Super Bowl XLV. Additionally, Pepsi Zero Sugar sponsored the Super Bowl LI Halftime Show, with American singer-songwriter Lady Gaga as the headlining performer. This sponsorship further elevated the brand's visibility and association with popular culture.
Another aspect of Pepsi Zero Sugar's marketing strategy is its packaging design. Pepsi Zero Sugar is packaged in a black can, distinct from the silver can of Diet Pepsi. This visual differentiation on grocery shelves helps consumers easily identify and recognize the product.
The target audience for Pepsi Zero Sugar is typically individuals who are health-conscious and seeking a sugar-free alternative to regular Pepsi. However, the product is also positioned to appeal to those who crave a fuller-bodied and more intense cola experience, similar to that of regular Pepsi. By emphasizing the extra caffeine and bolder flavour, the marketing campaigns aim to attract consumers who want more energy and a stronger-tasting drink without the sugar.
In summary, the marketing and advertising campaigns for Pepsi Zero Sugar focus on highlighting its unique flavour profile, higher caffeine content, and absence of sugar. Through creative narratives, celebrity endorsements, and strategic packaging design, PepsiCo has worked to establish Pepsi Zero Sugar as a compelling option for health-conscious individuals seeking a bolder cola experience.
