tab's popularity declined after the coca-cola company's introduction of diet coke in 1982, though it remained the best-selling diet soda of that year. coca-cola continues to produce tab in the united states, though in considerably smaller quantities than its more popular mainstay beverages, such as coca-cola and diet coke. according to the company, three million cases of tab were made in 2011, and the beverage has retained a cult following over the years. in 2006, a tab-branded energy drink was released, though it utilizes a different formula from the standard cola.
