Question: Were Jolt Cola and Diet Mountain Dew both sugar-free drinks, as advertised?
Context: Jolt Cola was a carbonated soft drink produced by The Jolt Company, Inc. (later known as Wet Planet Beverages).  The cola drink was created in 1985 by C. J. Rapp as a highly caffeinated beverage.  It was targeted towards students and young professionals, stressing its use as a stimulant in a similar manner as energy drinks. Its slogan reads "All the sugar, twice the caffeine!" "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. Caffeine-Free Pepsi-Cola was introduced, under the brand name Pepsi Free, in 1982 by PepsiCo as the first major-brand caffeine-free cola in years.  (The Canada Dry Company had marketed "Sport Cola," which was also caffeine-free, in the 1960s, but that brand of cola was not a success.)  A sugar-free variant, then known as Diet Pepsi Free, was also introduced.  The Pepsi Free name itself was phased out in 1987, and today these colas are known simply as Caffeine-Free Pepsi and Caffeine-Free Diet Pepsi.  The term "Free" had been reintroduced by PepsiCo on their Sierra Mist line in response to Coca-Cola's successful introduction of their Zero line (although the "Free" refers to a lack of sugar rather than caffeine, since Sierra Mist is already caffeine-free), though in 2008 that drink had reverted to its previous name of Diet Sierra Mist. 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. 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. 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. 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. Diet Pepsi and Diet Pepsi Classic Formula Blend (stylized as diet PEPSI CLASSIC SWEETENER BLEND) are no-calorie carbonated cola soft drinks produced by PepsiCo, introduced in 1964 as a variant of Pepsi-Cola with no sugar.  First test marketed in 1963 under the name Patio Diet Cola, it was re-branded as "Diet Pepsi" the following year, becoming the first diet cola to be distributed on a national scale in the United States.  In the 1960s and 1970s its competition consisted of Tab, produced by The Coca-Cola Company, and Diet Rite soda, produced by Royal Crown.  Diet Coke was a later entrant to the diet cola market; though shortly after entering production in 1982 it became the primary competing diet cola to Diet Pepsi. 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. "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.
