Cobranding is a partnership between two brands that intends to increase the value of each as a result of the association. Both large and small brands have partnered to gain advantages relative to competitors.
Cobranding can be complicated as when Jeep designs interiors with Burberry patterns. But, the connections can be really simple as in this example of a relationship between a brand of juice and Cartoon Network characters. The stickers make the product appealing to kids without altering the product or packaging. An easy solution for a small brand.
