Back By Popular DEWmand was a promotion held by Mountain Dew that returned discontinued flavors to shelves for a limited time.
On January 12, 2011, Mountain Dew announced via its official Facebook page that Pitch Black would be back on shelves after many years of fans pleading since it was originally released for a limited time in 2004. Pitch Black's return was heavily promoted with tours and giveaways.
It was later revealed that 2008's Supernova would return to stores alongside Pitch Black, both with updated label art that used the "Mtn Dew" logo format.
Typhoon was also made available for a limited time as a part of the promotion, and was only produced in 2-Liter bottles and only distributed at Walmart stores.
All three flavors stayed on shelves through June, and their limited run ended in July.
