Well, it looks like BB has mastered the art of the bull****. IMO, branding is what you do when your product is for ****. You are selling an ideal rather than a superior product. CU is a superior product in many ways and spending dough on branding is a waste...unless you are planning to fully engage in hucksterism.
Everyone brands. Especially the highest quality, super luxury brands.
This must just be an impression you have or a misconception of what branding is. You're way off base here, though.
Branding is basically the identity of your product. It's what that product means to people when they hear of it. Part of this can be creation of an icon. The concept is that having a single iconic image that represents your brand increases exposure of the brand and focuses it / imprints it in the consumer's mind. One of the great weaknesses of the CU branding campaign is that it had dozens of icons and, therefore, failed to imprint consumers with its overall branding message. Too many disconnects. A single icon is one step in the process, but it is not "branding".
It seems that the disconnect in this discussion (and the poor job CU did in communicating what was done) is that everyone is focusing on the icon and equating that with being the entirety of a branding program. That would be like saying that branding at Nike started and stopped when they drew a swoosh and decided to use it on all the company products.
