Carbonated water was added later by accident when Pemberton was mixing drinks for a friend and incidentally included it. His friends loved the new taste, so he altered the original formula to incorporate it. Coca-Cola was said to cure many diseases, including headaches, impotence, and the powerful morphine addiction. Three versions of Coca-Cola were on the market by 1888, sold by three separate companies. One company, Candler, purchased exclusive rights to the Coca-Cola formula from Woolfolk Walker, John Pemberton, and Margaret Dozier to cut out the competition. This made the first big break in Coca Cola history. Candler incorporated The Coca-Cola Company in 1982, and began marketing the product. The drink achieved the status of national icon for the USA by its 50th anniversary. Bottles of Coca-Cola were sold starting in 1894, and cans in 1955. The first bottle was sold in Vicksburg, Mississippi. In 1899, Chattanooga, Tennessee became the first site of a Coca-Cola bottling company.
