Mountain Dew

Mountain Dew is a brand of soft drink owned by the American company Pepsi and originating in America. Originally made in 1940 in Tennessee by bottlers Moses and Ally Hartman, it was revised by Bill Bridgeworth in 1958, with its contract being purchased by Tip, and undergoing further revisions to the formula in 1961 by William H. "Bill" Jones. It was eventually sold to the Pepsi company by 1964 and sold throughout America and Canada, and later to Japan by the 1980s.

Relation to the Metal Gear series
Series creator Hideo Kojima included in the Japanese release of Metal Gear Solid: Peace Walker Mountain Dew, alongside products from Axe Body Spray, Mountain Dew, fellow Pepsi-brand Pepsi NEX, Bon Curry, and magazines from Weekly Famitsu, Dengeki PlayStation, Dengeki Games, and Shonen Jump as a joke on product placement. Most of these were removed from the final release. The model viewer references its first revision of the formula for the drink in 1958.
