Diet Coke, known as Coca-Cola Light in some markets, has become a global phenomenon since its introduction in 1982. Marketed as a sugar-free and low-calorie alternative to Coca-Cola, it quickly gained popularity, becoming the third most popular carbonated drink in the world. A key element of Diet Coke's enduring appeal has been its branding, particularly the design of its cans. Over the past four decades, the Diet Coke can has undergone numerous transformations, reflecting changing consumer tastes, marketing strategies, and cultural trends.
The Origins of Diet Coke and its Iconic Silver Can
In the early 1980s, Coca-Cola recognized the growing demand for low-calorie beverages. To compete with Diet Pepsi, they initiated "Project Kansas," an internal project focused on developing a diet version of their flagship drink. Scientists at Coca-Cola headquarters in Atlanta refined the formula of TaB, an earlier diet soda, replacing saccharin with aspartame to eliminate its metallic aftertaste.
The result was Diet Coke, a beverage with a distinct taste profile. To differentiate it from regular Coke, the company chose a sleek silver can with bold red lettering. This was the first time the Coca-Cola brand name had been used on a new product since 1886, marking a significant departure from tradition. The silver can became an iconic symbol of Diet Coke, representing its modern, calorie-conscious appeal.
Marketing Campaigns and Shifting Can Designs
Diet Coke's marketing campaigns have been as diverse and dynamic as its can designs. The initial 1982 launch featured Hollywood glamour, showcasing the silver cans under spotlights. In 1994, the brand embraced urban energy with advertisements featuring neon-clad rollerbladers. Later campaigns targeted men, with the memorable "Diet Coke break" ads featuring construction workers.
In 2016, facing declining sales, Diet Coke underwent a major rebranding. The classic red branding was replaced with sleek silver cans and modern flavors targeted at design-conscious professionals. This shift aimed to revitalize the brand and appeal to a new generation of consumers. These marketing shifts often coincided with changes in can design. Limited-edition cans, collaborations with designers, and the introduction of new flavors all contributed to the evolution of the Diet Coke can. The can became more than just a container; it became a canvas for expressing the brand's identity and connecting with consumers on an emotional level.

The Extraordinary Story of How Diet Coke Came to Be
The Coca-Cola Company introduced Diet Coke to great fanfare in 1982, following another low-calorie cola called Tab that was produced in 1963. Although Tab was successful in the growing weight and calorie-conscious market, its name referring to âkeeping a tab on your weight,â the companyâs field tests and research on consumer attitudes indicated that sales were limited by its lack of the Coca-Cola trademark. The company began developing a different diet cola to replace Tab from 1975, which would have a renewed brand image and respond to the demand for a diet drink with better taste. The use of artificial sweeteners as a cheaper substitute for cane sugar saved the company around $100 million a year. The company president, Roberto Goizueta, had decided that high-fructose corn syrup would be used in regular Coke by 1980, suppressing the companyâs internal tensions between preserving and altering the original formula. In 1983 the company began using aspartame as the artificial sweetener for Diet Coke, initially blending it with saccharin. Moving away from the sugar market allowed the company to establish Diet Coke as a new product that called for bottlers, who purchased the syrup formula from the company, to sign new contracts. The previous agreement had only specified concentrates containing sugar, and coke executives held that neither Diet Coke nor regular Coke containing corn syrup applied to them. Amendments in the contract offered by Coca-Cola would allow the company to gain control over syrup prices. Despite protests from bottlers, the company won the legal battle in 1989 and Diet Coke was named as a new brand, with new ingredients and new contracts.
Diet Coke: A Cultural Icon
Diet Coke has had a significant cultural impact, including links with healthiness and wellness but also negative connotations in regards to body image. It has achieved high popularity in certain circles with loyal fans, including in popular culture. Victoria Beckham, Dua Lipa and Bill Clinton are known fans of the drink, and Donald Trump notably has a dedicated button for Diet Coke in his presidential office. The drink has been known to be the choice of "it girls", and has been popular in the fashion scene. Partly because of marketing reasons, connected to the public perception of the word "diet" and what it stands for, Coca-Cola launched Coca-Cola Zero as another sugarless cola product in 2005.
International Variations and Names
Since its inception in 1982, Diet Coke has been the product name in Coca-Cola's home country the United States and a number of other countries. Other countries, such as Germany (then West Germany) have used the Coca-Cola Light name since the beginning. This name is now most common in most of Europe, the Middle East, Latin America and Asia. In many countries including Italy, Mexico and the Netherlands, the product originally launched in 1983â84 under the "Diet Coke" name, but would later switch to the "Coca-Cola Light" name in the early 1990s.
Advertising Slogans Through the Years
Coca-Cola has used various slogans throughout Diet Coke's history to advertize the product, both in the United States and internationally. From 2010 to 2014, "Stay Extraordinary" was the main slogan in use. Coca-Cola launched the "You're on" campaign in 2014. However it was soon dropped after it was mocked, due to its unintentional drug reference (cocaine). Later that year, "Get a Taste" was introduced, asking the question "what if life tasted this good?". This campaign lasted until 2018.

Early on, to reduce costs, this was blended 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 aspartame. Other than sweeteners, Diet Coke differs from Coca-Cola by having a higher amount (approximately 33% more) of caffeine. The most commonly distributed version of Diet Coke uses aspartame as a sweetener. As one of the most intensively scrutinized food additives, the safety of aspartame has been studied since its discovery. Aspartame has been deemed safe for human consumption by the regulatory agencies of many countries.
