In 1886, Doctor John Pemberton sold the first glass today (5/8) in a downtown Atlanta pharmacy; The Coca Cola journey began.
While the look and slogans may have changed over the years (damn marketing people) the refreshing product has been a staple for over 135 years. (well except for that crazy new coke thing in 1985.)
Year one: about 8 glasses per day.
Today: 1.9 billion servings per day.
Lesson: Change is good; even if its just how people look at you.
