Co-branding strategies are increasing used to fend off heavy competition and to gain more marketplace exposure (Spethmann & Benezra 1994). The main advantages are that companies can pool together their resources, reduce the cost of production introduction and generate greater sales (Kolter et al. 2006, p. 408; Samu, Krishnan & Smith 1999, p. 57).
Co-branding also allow brands with lesser reputation to leverage on partner brands of higher reputation.

Levin, Davis and Levin (1996, pp. 298-299) in a taste-test study reported that there were improvement in product evaluations of unknown brands when a well-known branded ingredient is added.
Although co-branded products are perceived as processing "the best of all worlds" attributes which capitalize on the unique strengths of each contributing brand (Leuthesser, Kohli & Suri 2003, p. 39).

Mismatch could occur when combining two brands, thus co-branding may affect partner brands negatively (James 2005, p. 22).
In addition, overall brand equity could be damage when consumers attribute any negative experience with one constituent brand (Washburn, Till & Priluck 2000, p. 594). Hence, either partner in co-branding can undermine the credibility of each another, and
