"For 25 years, a 26-ounce drink was the biggest soda a person could buy. Then in 1980, a shift occurred when 7-Eleven began its Big Gulp campaign. Big Gulp fountain drink cup sizes steadily rose throughout the decade and beyond, beginning at 32 ounces in 1980, then climbing to 44 ounces in 1986, 64 ounces in 1989, and a behemoth 128 ounces in 2006. Called the Team Gulp, the 128-ounce cup holds a gallon of soda."
Wine is lagging behind. More wine please... :)
