About

Coca-Cola is the best selling soft drink in the world. It is believed that approximately 94 percent of the world can recognize the Coca-Cola logo. It all began in 1886 by a pharmacist named Dr. John S. Pemberton. Pemberton died just two years after the introduction of Coca-Cola so he saw only a fraction of its success. A person named Asa Griggs Candler took over Coca-Cola for $2,300. Candler created a marketing campaign by offering free Coke coupons to consumers to inspire them to rebuy Coca-Cola after they tried the soda and enjoyed the taste. Similarly to Coca-Cola’s heavy advertising campaign today, Candler also made sure the Coca-Cola logo was seen on a large scale. These two marketing campaigns helped the Coca-Cola brand move from a regional market to the national stage. It quickly became one of best selling fountain drinks.
