Diet Pepsi, known as Pepsi Light in some regions, is a sugar-free cola alternative produced by PepsiCo. Originally test-marketed as Patio Diet Cola in 1963, it was rebranded as Diet Pepsi the following year. This move made it the first diet cola to achieve national distribution in the United States, later expanding overseas. Over the years, Diet Pepsi has become a cultural icon, and its branding, including T-shirts, reflects its dynamic history.
The Origins of Diet Pepsi
In 1963, Diet Pepsi was initially introduced in the United States under the name Patio. The positive reception, driven by changing dietary habits among Baby Boomers, led to its national launch as Diet Pepsi the following year. Since then, the product's distribution has reached numerous countries worldwide.
Diet Pepsi initially competed with The Coca-Cola Company's Tab in the 1960s and 1970s. However, the introduction of Diet Coke in 1982 provided the principal competition to Diet Pepsi. In 1986, Diet Pepsi held the fourth-highest soft drink sales position in America, capturing a 4.3 percent market share, just below Diet Coke's 7.1 percent. By 2000, Diet Pepsi's share had increased slightly to 4.7 percent, ranking seventh, with Dr Pepper, Sprite, and Mountain Dew (also a PepsiCo brand) ahead, while Diet Coke remained third. As of 2010, Diet Pepsi accounted for 5.3 percent of all carbonated soft drink sales in the U.S., holding the #7 soft drink brand position by volume.
PepsiCo has since introduced other sugar-free cola drinks, including Pepsi Max in 1993, primarily in Europe, and Pepsi One in 1998 for the United States. Various Diet Pepsi/Pepsi Light variations have emerged, incorporating flavors like wild cherry, vanilla, lemon, and lime. Additionally, Caffeine-Free Diet Pepsi, the first Diet Pepsi variant, was launched in 1982 and remains available today.
Although Diet Pepsi is marketed globally as a low- or no-calorie beverage, the specific ingredients may differ by country of origin.

Packaging and Logo Evolution
When Diet Pepsi was first introduced in 1964, it was available in glass bottles and cans. The logo used in packaging and advertising has undergone numerous changes since its original design. In October 2008, PepsiCo announced a redesign of its logo and rebranding for many products, including Diet Pepsi. The brand's blue and red Pepsi Globe logo was transformed into a series of "smiles," with the white band in the center arcing at various angles based on the product. The Classic Sweetener Blend variety featured the 2003-2006 wordmark alongside the "smile" logo and a light blue label, contrasting with the silver label of the modern formulation. By mid-2017, the Classic Sweetener Blend packaging replaced the 2003 wordmark with the modernized version.
Diet Pepsi T-Shirts Through the Years
Diet Pepsi T-shirts have mirrored the brand's logo and marketing evolution. Early T-shirts likely featured the original Pepsi-Cola logos, reflecting the brand's initial emphasis on health and refreshment. As the logo evolved, so did the T-shirt designs, incorporating the red and white bottle cap logo of the 1950s and the globe logo of the 1970s.
The "Pepsi Generation" campaign in the 1960s, which branded Pepsi as the choice for young, energetic consumers, likely influenced T-shirt designs, with bolder graphics and slogans targeting a younger demographic. The minimalist globe logo of the 1970s would have translated well to T-shirts, offering a clean and recognizable design.
In the 1980s and 1990s, when Pepsi embraced celebrity endorsements, T-shirts may have featured images of stars like Michael J. Fox, Cindy Crawford, and Ray Charles, aligning the brand with popular culture. The logo changes of the 1990s, with the separation of the globe and wordmark, would have offered new design possibilities for T-shirts, allowing for more dynamic and modern graphics.
The 2000s saw further evolution in T-shirt designs, reflecting the brand's focus on coolness and innovation. The 3D globe logo and the updated Pepsi font would have been incorporated into apparel, appealing to a contemporary audience. The 2008 redesign, with the "smile" logo, marked a significant shift, and T-shirts featuring this design would have aimed to convey a sense of friendliness and approachability.

Today, Diet Pepsi T-shirts often incorporate retro designs, paying homage to the brand's heritage. These shirts may feature vintage logos and slogans, appealing to nostalgia and brand loyalty.
Advertising and Celebrity Endorsements
While initially promoted alongside Pepsi, Diet Pepsi began to be advertised independently in the late 1960s. The first television advertisement focusing solely on Diet Pepsi, "Girlwatchers," emphasized the cosmetic benefits of the beverage. The jingle from this ad became so popular that it was recorded, played on the radio, and eventually became a Top 40 hit.
Since its beginning, Diet Pepsi has prominently featured musicians, athletes, and actors in its promotions. In 1985, Super Bowl XIX quarterbacks Joe Montana and Dan Marino appeared together in a Diet Pepsi ad. In the late 1980s, Michael J. Fox starred in commercials for Diet Pepsi, including one where he created a robot clone of himself. During the early 1990s, R&B singer Ray Charles was featured in a series of Diet Pepsi ads with the tagline "You got the right one, baby!" Supermodel Cindy Crawford also became a recurring celebrity endorser, starting with a 1991 ad where she buys a can of Diet Pepsi from a vending machine on a hot day.
The "Skinny Can" and Fashion Week
In February 2011, Diet Pepsi introduced the "Skinny Can" at New York's Fall 2011 Mercedes-Benz Fashion Week. This launch included fashion events and collaborations with designers Charlotte Ronson and Betsey Johnson. According to Jill Beraud, Chief Marketing Officer of PepsiCo, Diet Pepsi has a long history of celebrating women through iconic fashion imagery and was proud to continue that tradition as an official sponsor of Mercedes-Benz Fashion Week. The slim, attractive new can was positioned as the perfect complement to stylish looks.
Fashion commentator Simon Doonan created a window installation at the Diet Pepsi Style Studio in Soho, incorporating the new cans and Jonathan Adler designs. Charlotte Ronson designed an exclusive T-shirt inspired by Diet Pepsi, which was given to attendees at her show and after-party.

Pepsi Logo History: A Constant Reimagining
Pepsi's logo history is marked by constant evolution. From its beginnings as Brad's Drink to its current form, the logo has undergone numerous redesigns, including changes to the type of logo, fonts, and colors.
Early Years: Brad's Drink and the First Pepsi-Cola Logos
Before Pepsi was Pepsi, it was Brad's Drink, created by pharmacist Caleb Bradham in 1893. The Brad's Drink logo featured a blue wordmark on a white background. In 1898, Brad's Drink became Pepsi-Cola, named after the word "dyspepsia." The first Pepsi-Cola logo, like Brad's Drink, had spiky embellishments in its font, but the main color changed to red. In 1903, Bradham trademarked the name, and by 1910, there were 240 Pepsi-Cola bottling franchises across 24 states.
The 1900s-1930s: Softening the Logo and Facing Challenges
In 1905, the logo became softer, with retracted spikes and wider letters. The logo changed again in 1906, remaining red and wavy. The 1920s and 1930s were challenging for Pepsi-Cola, with the company declaring bankruptcy and being purchased by Craven Holdings Corp.
1933: Differentiating from Coca-Cola
In 1933, Pepsi-Cola differentiated itself by offering 12-ounce bottles at the same five-cent price as Coca-Cola's 6.5-ounce bottles. The final red and white logo of this era would later resurface on throwback Pepsi cans.
1940s: Classic Lettering
The 1940 version of Pepsi-Cola’s logo featured classic lettering, with shrinking serifs on the smaller letters and taller, wider larger letters.
1950s: The Bottle Cap Logo
In 1950, Pepsi introduced its bottle cap logo, marking the first time the color blue was associated with the brand. The wordmark remained the same, but it was now placed on a tangible canvas. During this decade, Pepsi-Cola branded itself as the soda that delivers better value, with the tagline "More bounce to the ounce."
1960s: Symmetrical Look and the Pepsi Generation
In the 1960s, the Pepsi logo took on a more symmetrical look. With its Pepsi Generation campaign, Pepsi branded itself as the soda choice for young, high-energy forward-thinkers.
1970s: Minimalism and the Globe Logo
Pepsi embraced 1970s minimalism when it switched to the globe logo in 1973. The logo had a colored background for the first time, with red on the left and light blue on the right. The font remained unchanged but shrank to fit inside the globe's perimeter.
1975: The Pepsi Challenge
In 1975, Pepsi launched the Pepsi Challenge, a campaign to prove that its soda tasted better than Coca-Cola.
1980s: The Cola Wars and Celebrity Endorsements
By the early 1980s, Pepsi outsold Coca-Cola in supermarkets. In 1987, Pepsi gave the globe logo a facelift, introducing its own unique font with a futuristic feel.
1990s: Separating the Globe and Wordmark
In 1991, Pepsi changed its logo dramatically, separating the globe and wordmark. The italicized word "Pepsi" stretched across the top of the logo in blue. In 1998, Pepsi flipped the colors in its logo, with the globe moving up and over to sit just below the wordmark.
2000s: The Joy of Cola and 3D Effects
In 1999, Pepsi launched a new slogan and brand campaign: "The Joy of Cola." In 2003, the logo received a tweak, and in 2006, the globe became a three-dimensional glass of soda with condensation.
2008: The Smile Logo
In 2008, Pepsi underwent a significant redesign, flattening the 3D globe and introducing a new font. The new logo evoked a smile, conveying a sense of friendliness.
Current Logo: Throwback to the ‘60s and ‘70s
The current version of the Pepsi logo throws it back to the ‘60s and ‘70s, with tweaks to the typography.
