The Starbucks Red Cup, also called the Starbucks holiday cup, is a modern Christmas and holiday season tradition[1][2] and promotional campaign operated by coffee chain Starbucks; each winter, some hot drinks served at Starbucks cafés will be served in cups with a red background and various festive designs instead of the regular white cups. New designs are used each year. Starbucks have used the campaign to support HIV/AIDS research. In 2015 the cups were plain red without the festive designs, and were accused of being anti-Christian.
But new Christmas rituals that reflect contemporary life are slowly becoming a familiar part of the season. ... "We know that as soon as the red cups come to Starbucks, Christmas is here," says a spokesman for retail analysts Allegra Strategies.
