Coca-Cola was invented in 1886 by Dr. John Pemberton and first sold in Atlanta. It grew rapidly under Asa Candler's ownership and marketing expertise from the late 1880s. By the 1920s, Coca-Cola had become a global brand through franchising to independent bottlers and expansive advertising. Over the 20th century, Coca-Cola diversified its product line and made numerous acquisitions, including Columbia Pictures. It remains the largest beverage company in the world.
