"Can you believe that in the 1950s, Coca-Cola was packaged in 6.5-ounce bottles? No one even makes those anymore. Twelve-ounce cans came next, and now you can get a super-sized soft drink at a fast food restaurant containing 42 oz. That's more than one liter! The original Coke was 81 calories. The super-sized beverage is 410 calories (it would be more, but you get lots of ice included)."
