Packaging and logo When it was first introduced in 1964, Diet Pepsi was packaged in glass bottles, and was also made available in can format. In 1994, Diet Pepsi became the first product to list a "freshness date" on each individual can and bottle, a practice that would later become a widespread standard in the packaged food and beverage industry. As of 2020, the product is distributed in plastic bottles, cans, and glass bottles, as well as via soda fountains in retail operations such as restaurants and convenience stores. The logo used in the packaging and advertisement of Diet Pepsi has changed multiple times since its original iteration. In October 2008, PepsiCo announced it would be redesigning its logo and re-branding many of its products, including Diet Pepsi. 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. In the case of Diet Pepsi, the logo consisted of the small "smile". Starting in mid-2010, all Pepsi variants, both regular and diet, began using the original "smile" logo. The Classic Sweetener Blend variety was distinguished by its use of the 2003-2006 wordmark along with the "smile" logo, and a light blue label background in contrast to the modern formulation's silver label. By mid-2017, packages of Classic Sweetener Blend dropped the 2003 wordmark and began using the modernized wordmark instead. With the restoration of aspartame as the main sweetener in the regular version, the alternate label was dropped, and packages bore the title "Classic Diet Pepsi Taste" which is very reminiscent to the "Coca-Cola Classic" title that was in use from 1985 to 2009, when New Coke received backlash. Advertising and promotion While it was initially advertised alongside Pepsi, Diet Pepsi began to be promoted independently in the late 1960s. The first television advertisement to feature Diet Pepsi as a standalone product was "Girlwatchers," which placed focus on the cosmetic aspects of the beverage. 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. Since its inception, musicians, professional athletes, actors and actresses have been featured prominently in the promotion of Diet
