‘Soft drink’, refers to any of a class of nonalcoholic beverages, usually but not necessarily carbonated, containing a natural or artificial sweetening agent, edible acids, natural or artificial flavors, and sometimes juice (Bert, 2011). The term was originated to distinguish the flavored drinks from hard liquor, or spirits. Marketing of carbonated soft drinks dates back to 17th century to imitate the popular and naturally effervescent waters of famous springs, with primary interest in their reputed therapeutic values. The concept of brand loyalty has had a long and inconsequent history. The very first mention of the idea was attributed to Copeland (1923) and since then, over 200 definitions have appeared in the literature (Jacoby & Chestnut, 1978). Consumer’s exhibit varied tendencies as regards their purchase behavior. Whereas others are very loyal, others are spuriously loyal and others are quite indifferent in their purchase behavior.
