The Pepsi-Cola Made with Real Sugar, formerly called Throwback, is a brand of soft drink sold by PepsiCo in the United States and in sweet stores in South Australia for its flagship Pepsi and Mountain Dew brands.
 The drinks, called Pepsi Throwback and Mountain Dew Throwback, are named as such because they are flavored with cane sugar and beet sugar instead of high fructose corn syrup, which soft drink companies used to replace sugar (in their North American products) in the 1980s.
 In addition, these drinks use retro packaging.
 As of June 2014, Pepsi Throwback has been replaced in some areas of the United States by "Pepsi-Cola Made with Real Sugar", a new product formulation, also made without high fructose corn syrup.
Anuja Chauhan (Hindi: अनुजा चौहान ; born 1970) is an Indian author and advertiser, often described as 'the best writer of the Indian commercial fiction genre.'
 She worked in the advertising agency, JWT India, for over 17 years, eventually becoming vice-president and executive creative director, before resigning in 2010 to pursue a full-time literary career.
 Over the years she worked with brands like Pepsi, Kurkure, Mountain Dew and Nokia, creating Pepsi's "Nothing official about it" campaign and advertising slogans such as Pepsi's "Yeh Dil Maange More" and "Oye Bubbly".
In addition to Pepsi's Mountain Dew, Coca-Cola's Mello Yello or Dr Pepper's Sun Drop, there are a variety of smaller or regional brands for citrus soda.
 In deference to Mountain Dew's leading position in the market segment, some brands also use the word "Mountain" in their names.
Pepsi is a carbonated soft drink produced and manufactured by PepsiCo.
 Originally created and developed in 1893 and introduced as Brad's Drink, it was renamed as Pepsi-Cola on August 28, 1898, and then as Pepsi in 1961.
Diet Mountain Dew is a no-calorie Mountain Dew that was first introduced in 1986.
 It was formerly known as "Sugar-Free Mountain Dew" until 1986, when it was given its current name.
 In 2006 Diet Mountain Dew was reformulated with a new "Tuned Up Taste", using a blend of sucralose, aspartame, and acesulfame potassium as sweeteners.
 The previous formulation was sweetened exclusively with aspartame.
 In limited areas in the United States, Diet Mountain Dew has treated water instead of carbonated water as a fountain drink.
"Diet Mountain Dew" (sometimes stylized as Diet Mtn Dew) is a song by American singer and songwriter Lana Del Rey, taken from her second studio album "Born to Die" (2012).
 It was released as the album's first promotional single on June 13, 2011 by Universal Music Group.
The Mountain Dew Vertical Challenge (abbreviated MDVC) began in 1991 and is a series of free casual ski and snowboard races held on mountains throughout the northeast during each winter season, sponsored by Mountain Dew.
 Skiers and snowboarders are divided by gender and age group to compete for gold, silver, and bronze medals in each category.
 In addition to the race, prizes are given away throughout the day at a mountain for various reasons.
"Good Old Mountain Dew" (ROUD 18669), sometimes called simply "Mountain Dew" or "Real Old Mountain Dew", is an Appalachian folk song composed by Bascom Lamar Lunsford and Scotty Wiseman.
 There are two versions of the lyrics, a 1928 version written by Lunsford and a 1935 adaptation by Wiseman.
 Both versions of the song are about moonshine.
 The 1935 version has been widely covered and has entered into the folk tradition becoming a standard.
Mountain Dew (sometimes stylized as Mtn Dew) is a carbonated soft drink brand produced and owned by PepsiCo.
 The original formula was invented in 1940 by Tennessee beverage bottlers Barney and Ally Hartman.
 A revised formula was created by Bill Bridgforth in 1958.
 The rights to this formula were obtained by the Tip Corporation of Marion, Virginia.
 William H. "Bill" Jones of the Tip corporation further refined the formula, launching that version of Mountain Dew in 1961.
 In August 1964, the Mountain Dew brand and production rights were acquired from Tip by the Pepsi-Cola company, at which point distribution expanded more widely across the United States and Canada.
Surge (sometimes styled as SURGE) is a citrus flavored soft drink first produced in the 1990s by The Coca-Cola Company to compete with Pepsi's Mountain Dew.
 Surge was advertised as having a more "hardcore" edge, much like Mountain Dew's advertising at the time, in an attempt to lure customers away from Pepsi.
 It was originally launched in Norway as Urge, and was so popular that it was later released in America as Surge.
 Lagging sales caused production to be ended in 2006 for most markets, and by 2014 Norway was the last country where either Urge or Surge were still sold.
