National brands appeal to customers due to their widespread availability and brand recognition. Examples include Coca-Cola and Pepsi. Private brands are only available at certain retailers but offer lower prices. Examples are store-name products like Target's Up & Up brand. Brand extensions leverage brand equity by applying the brand to related products, like Gatorade's various sports drinks. However, extensions risk diluting the original brand if not closely related. Co-branding partnerships combine two brands for mutual benefit, such as Betty Crocker brownie mix including Hershey's chocolate syrup.
