20th century
The first outdoor wall advertisement that promoted the Coca-Cola drink was painted in 1894 in Cartersville, Georgia. Cola syrup was sold as an over-the-counter dietary supplement for upset stomach. By the time of its 50th anniversary, the soft drink had reached the status of a national icon in the USA. In 1935, it was certified kosher by Atlanta Rabbi Tobias Geffen, after the company made minor changes in the sourcing of some ingredients.
The longest running commercial Coca-Cola soda fountain anywhere was Atlanta's Fleeman's Pharmacy, which first opened its doors in 1914. Jack Fleeman took over the pharmacy from his father and ran it until 1995; closing it after 81 years. On July 12, 1944, the one-billionth gallon of Coca-Cola syrup was manufactured by The Coca-Cola Company. Cans of Coke first appeared in 1955.
