1985-1992 (primary), 2019 (limited re-release)
New Coke was introduced by The Coca-Cola Company on April 23, 1985 as a reformulation of the company's flagship soft drink. Having been met with massive consumer backlash during its inception, the company eventually re-released the original formulation 79 days after the debut of the new formula, which has since been rebranded as "Coca-Cola Classic" to distinguish itself from New Coke.
On May 21, 2019, The Coca-Cola Company announced that New Coke would be relaunched for a limited time, as part of a partnership deal with Netflix to promote the third season of Stranger Things. And as such, Coca-Cola's online shop and social media profiles were eventually redesigned for a brief time to promote this limited re-release.
The "NEW!" banner would eventually be dropped a year later.
