The brand love (BL) paradigm combines the emotional attachment theory with consumer behavior studies, revolving around the impact of deep-seated emotions on consumer-brand relationships. Researchers of this paradigm conceptualize and empirically verify the consumer’s passionate love for the brand is the primary driver of brand loyalty. In a series of research projects, Roberts (2004), Ahuvia (2005) and Thomson et al. (2005) systematically analyze how and why passionate love can lead to strong and long-lasting brand loyalty. Besides, Whang et al. (2004) report empirical
verification on brand love as an essential factor in enhancing brand loyalty; three dimensions of such love are proposed: passion, possessiveness and altruism. Of late, brand marketing scholars including Carroll and Ahuvia (2006), Albert et al. (2008), Fedorikhin et al. (2008), Park et al. (2009) and Carlson et al. (2009) report findings that prove passionate love for the brand originates from brand attachment and predicts brand loyalty; the passionate love that the consumer feels for the brand is found metaphorically analogous to the romantic love existing in interpersonal relationships. Such analogy points to the possibility of transforming a brand relationship into a romantic relationship in which the consumer becomes so strongly attached to the brand that he or she is durably loyal to it.
