It is not surprising that the birthplace of cola was the hot and humid American South. This region had long specialized in creating delicious soft drinks. A druggist in Atlanta, Georgia named John Pemberton created the most well–known drink brand in the world in the 1880s. However, it seems clear that he had no idea how big it would become.

Like many American pharmacists of the day, Pemberton was opposed to the drinking of alcohol and wanted to produce a stimulating soft drink. First, he made "the French Wine of Coca," made from the coca leaf. Then he began to experiment with the cola nut. Eventually, he managed to make a combination of the two that he thought was sweet, but not too sweet. Deciding that "the two C's would look well in advertising," he named it Coca–Cola.

Pemberton's invention caught on fairly quickly. By 1905, "Coke" was being advertised all over the country as "The Great Natural Temperance Drink." The drink enjoyed additional success since there was a large and popular temperance movement in the US at that time. In the 1920s, alcohol was outlawed, and sales of Coke rose significantly. However, they continued to rise even after the law was repeated.

Another reason for Coke's popularity was good business sense. A year after he invented it, Pemberton had sold Coca–Cola to Asa Griggs Candler for only $283.26! Candler was a marketing genius, and by the time he sold the Coca–Cola Company in1919, it was worth $25 million.

Which of the following is responsible for Coke’s additional success?
