PepsiCo launched the berry-flavoured soda Pepsi Blue in 2002 but, despite relentless promotion from the likes of Britney Spears and the New York Mets, sales of the blue beverage were disappointing and the drink was axed in 2004 in the US and Canada, although it is still sold in parts of Asia.

However, despite its previous flop, Pepsi brought the drink back to American stores for a limited time in 2021. From May that year, the brightly-coloured beverage was back on store shelves "everywhere that Pepsi products are sold" in 20-ounce bottles and multi-packs for as long as stocks lasted. The move was down to a group of "passionate Pepsi Blue fans [who] have been clamoring for the return of their beloved berry cola", according to PepsiCo's press release.
