Coca-Cola is bidding farewell to Tab, the company’s first-ever diet soda that became a cult favorite in the 1970s, after sales in the US fizzled. 

The soft drink giant on Friday announced it will phase out the soda as well as other under-performing products by the end of 2020 as it works to streamline its beverage lineup amid a challenging year.

‘We’re forever grateful to TaB for paving the way for the diets and lights category, and to the legion of TaB lovers who have embraced the brand for nearly six decades,’ Coke group director Kerri Kopp said in a statement. 

‘If not for TaB, we wouldn’t have Diet Coke or Coke Zero Sugar. TaB did its job.’
