Coca-Cola returned to India in 1993 after a 16 year absence, taking over the top soft drink brand and bottling network in the country. It produces syrup concentrate which is sold to various bottlers who hold exclusive territories. These bottlers produce and distribute the final drink by mixing the syrup with water and sweeteners. Coca-Cola employs mass production and uses an efficient franchised production model. It conducts extensive marketing research and promotion using the 4 P's framework. Some of its most iconic ad campaigns feature Santa Claus and the slogan "I'd like to buy the world a Coke". It is a major sports sponsor of events like the Olympics and FIFA World Cup.
