A beverage so iconic that it inspired an entire genre of soft drinks named after it, Coca-Cola had its start in 1886 when it was created by pharmacist John Pemberton, who initially intended to market it as a temperance drink and medicinal tonic.

A blend of coca leaves and kola nuts (a source of caffeine), the iconic soft drink became a sensation, and soon Pemberton sold the ownership rights to Asa Griggs Candler, a businessman who transformed the Coca-Cola brand into a global powerhouse. While the ingredients have been changed a few times since its inception, the current formula remains a closely guarded trade secret, fueling much speculation and numerous attempts to uncover it.

Developed in 1898 by pharmacist Caleb Bradham—and originally named "Brad's Drink"—Pepsi was initially conceived as a digestive aid. Its name is derived from pepsin, a digestive enzyme produced by the body, though pepsin was never actually included in the drink's formula.

Despite nearly going bankrupt in the early 1920s, Pepsi gained popularity during the Great Depression, even briefly outpacing Coca-Cola, thanks to clever marketing that appealed to budget-conscious consumers. This kickstarted a fierce rivalry, leading to bold marketing stunts, including an unlikely deal with the Soviet Union, making Pepsi the first Western product sanctioned for sale there.

Another soft drink originally conceived in a pharmacist's lab, Dr Pepper actually predates both Coke and Pepsi. Launched in 1885 in Waco, Texas, its unique flavor sets it apart from most competitors. In fact, the U.S. Food and Drug Administration has categorized Dr Pepper, much like Coca-Cola, as its own distinct type of beverage: "pepper soda."

The origin of its name is disputed. Originally, people would simply order a "Waco" at soda fountains. While some speculate the name comes from Charles T. Pepper, a doctor who gave Wade Morrison his first job (or, according to another version, gave him permission to marry his daughter), it was more likely than not a creative marketing decision, as using "Dr." in product names was a common way to suggest health benefits.

7UP, created in 1929 by Charles Leiper Grigg, was originally marketed as "Bib-Label Lithiated Lemon-Lime Soda," as it contained lithium citrate (a mood-stabilizing drug) among its ingredients. While lithium was removed in 1948, the drink's refreshing lemon-lime flavor remained, having already become a household favorite.

The soft drink, however, didn’t quite find its market niche until it launched the "Uncola" marketing campaign in the 1970s, which positioned the soda as a distinct alternative to colas, boosting its popularity. The origin of the name 7UP remains a mystery, with speculation that it refers to the original 7-ounce bottles or the drink’s initial seven ingredients.

Introduced by Coca-Cola in 1961 to compete with 7UP, Sprite quickly became one of the leading lemon-lime sodas on the market. Interestingly, this popular soft drink didn’t originate in America but in West Germany in 1959, where it was launched as "Fanta Klare Zitrone" ("Fanta Clear Lemon" in English).

In the ‘80s, Sprite leveraged its appeal to younger generations through bold advertising campaigns and endorsements from popular musicians. Today, the brand has expanded into various flavors, including cranberry, cherry, grape, orange, tropical, ginger, and vanilla, among others.

Mountain Dew was originally created in the 1940s by Tennessee beverage bottlers Barney and Ally Hartman as a mixer for whiskey. The name "Mountain Dew" was a colloquial term for homemade liquor, making it fitting for the soda’s Appalachian roots. However, the drink only took on its citrus-flavored, energizing modern form after being acquired by the Tip Corporation in 1961.

It remains one of the most caffeinated sodas on the market, containing 54 mg of caffeine per 12-ounce can—nearly double that of Coca-Cola. This is likely what draws many soda drinkers to this flavor, as the high sugar and caffeine content can give a short-term boost of energy.

Founded in 1905 by Claud A. Hatcher, Royal Crown Cola (RC Cola) was originally created as a direct competitor to Coca-Cola and Pepsi. The soft drink was born after the Hatcher family, who were grocery store owners, could not get a discount for purchasing large volumes of Coca-Cola syrup from local distributors. Frustrated, they vowed to create their own alternative.

Despite never achieving the same market dominance as Coke or Pepsi, RC Cola soon gained a loyal following, especially in Southern states. Unlike its rivals, RC offered a slightly stronger cola flavor, which many found refreshing compared to the sweeter taste of Coke. RC Cola also innovated with the first aluminum can for sodas and was one of the first companies to produce diet sodas, such as Diet Rite.

Did you know that Fanta was born in Germany during World War II, of all places? After local Coca-Cola plants could no longer import syrup due to trade embargos, German businessman Max Keith created a new soda using available ingredients—which were mostly fruit scraps and whey.

Fanta quickly became a wartime favorite in Germany. After the war, Coca-Cola regained control of the plant, formula, and trademarks, introducing Fanta to the U.S. in 1955. It rapidly gained popularity as a fun, fruit-flavored alternative to traditional sodas. While Fanta's orange flavor remains its best seller, the brand now offers over 90 flavors worldwide.

A&W Root Beer was introduced in 1919 by Roy Allen, who first started selling it at a parade honoring returning World War I veterans. Its creamy texture and rich flavor quickly made A&W Root Beer a favorite, especially when paired with vanilla ice cream to create the now-iconic root beer float.

By 1922, Roy Allen partnered with fellow entrepreneur Frank Wright, and A&W became a franchised brand, launching one of the first fast-food chains in America that same year. Despite struggling with labor shortages and sugar rationing during World War II, the company endured and remains one of the most iconic root beer brands in America to this day.

Sunkist, launched in 1979 by the Sunkist Growers cooperative, was introduced to tap into the American love for citrus-flavored sodas. Known and loved for its bold orange flavor, Sunkist was the first major orange soda to include caffeine in its formula, setting it apart from competitors like Crush and Fanta.

Most importantly, Sunkist's success was greatly boosted by its association with the California citrus industry. Its marketing campaigns, including the "Taste the Sun" slogan, further linked the brand to sunny, vibrant outdoor activities, making it one of the top-selling orange sodas in the U.S. for decades.
