Following a positive reception attributed to the shifting dietary habits and preferences among Baby Boomers, the drink was launched nationally as Diet Pepsi the following year.

[13] In December 2012, an AP article reported that Diet Pepsi was changing its sweetener to sucralose ahead of a major rebranding of the soft drink set for January 2013.

[17] Additional variations of Diet Pepsi have been introduced over the years, wherein other flavors (such as wild cherry, vanilla, lemon, and lime) have been added to the cola.

[22] Though Diet Pepsi is represented worldwide as a low- or no-calorie beverage, the ingredients comprising its makeup vary in some cases by the country of origin.

In 1994, Diet Pepsi became the first product to list a "freshness date" on each individual can and bottle,[34] a practice that would later become a widespread standard in the packaged food and beverage industry.

[36] At this time the brand's blue and red Pepsi Globe logo became a series of "smiles," with the central white band arcing at different angles depending on the product.

The musical jingle from this ad generated popular culture appeal to the extent that it was eventually recorded and played on the radio, and later became a Top 40 hit.

In 1985, immediately following Super Bowl XIX, the game's respective quarterbacks, Joe Montana (of the San Francisco 49ers) and Dan Marino (of the Miami Dolphins), met in a hallway of what appeared to be a football stadium.

[42] In exchange, the film's production studio, Paramount Pictures, included a 60-second Diet Pepsi advertisement on all Top Gun VHS tapes.

"[45] Supermodel Cindy Crawford became a recurring celebrity endorser for the Diet Pepsi brand at this time as well, beginning with a 1991 television ad in which she purchases a can of the drink from a vending machine on a hot summer day.

Cindy Crawford was also brought back in 2002 to introduce a new packaging design for Diet Pepsi, and again in 2005 to promote the revised slogan "Light, crisp, refreshing" with an ad which debuted during Super Bowl XXXIX.

[46] In 2005 and 2006, recording artist Gwen Stefani appeared in advertisements related to a campaign in which codes printed underneath Diet Pepsi bottle caps could be redeemed for music downloads on Apple's iTunes Store.
