‘Soft drink’, refers to any class of non-alcoholic
beverages, usually but not necessarily carbonated,
normally containing a natural or artificial
sweetening agent, edible acids, natural or artificial
flavors, and sometimes juice (Vaux, 2011). The
term originated to distinguish the flavored drinks
from hard liquor, or spirits. Marketing of
carbonated soft drinks dates back to 17
th
century to
imitate the popular and naturally effervescent
waters of famous springs, with primary interest in
their reputed therapeutic values. Since then there
have been many diverse brands from different
producers (Branske, 2011). Buyers tend to be brand
loyal to certain brands and others are indifferent.
Although some consumers are said to be totally
brand loyal, others are spuriously loyal, and others
are quite indifferent in their purchase behavior.
Whereas most of the studies have occurred in
developed countries, little has been done in
underdeveloped and developing nations.
