Thinking that two C's looked well in advertising, Dr Pemberton's partner and bookkeeper, Frank M. Robinson, suggested the name and so the famous trademark Coca-Cola was born. During its first year, sales averaged nine drinks per day. Today it is one of the most popular soft drinks.
The formula for Coke, remains a trade secret, but originally contained an uncertain amount of cocaine, though this was reduced over time (falling to 1/400th of a grain, or 0.16 milligrams, per ounce of syrup, by 1902), and eliminated around 1906 as health regulations were tightened. Nevertheless, Coca-Cola has been criticized for its possible negative health effects, with many urban myths surrounding it. In addition, the commercial success of the drink has been periodically challenged, in particular by its main rival Pepsi-Cola.
However, the popular soft drink has never been green. This myth might have come around because at one point it was manufactured in green bottles.
