New Coke is back in the news. Earlier this year, The Coca-Cola Co. announced a limited re-release of New Coke as a promotional tie-in with the third season of the Netflix show “Stranger Things.” The science fiction series’ third season is set in 1985, the year that New Coke replaced the original Coke formula, which was reintroduced and rebranded “Coca-Cola Classic” less than three months later.
