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 2010, the product is distributed in plastic recyclable 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. The shortest-lived logo for Diet Pepsi was in 2007-2008. In October, 2008, PepsiCo announced it would be redesigning its logo and re-branding many of its products, including Diet Pepsi, although the drink continued to use the 2007-2008 logo until very early 2010. At this time the brand's blue and red globe trademark became a series of "smiles," with the central white band arcing at different angles depending on the product. The new imagery has started to be used. In the case of Diet Pepsi, the logo consists of the small "smile".
Starting in mid-2010, all Pepsi variants, both regular and diet, began using the medium-sized "smile" logo.
