Brand monopoly

In economic terms the "brand" is a device to create a monopoly — or at least some form of "imperfect competition" — so that the brand owner can obtain some of the benefits which accrue to a monopoly, particularly those related to decreased price competition. In this context, most "branding" is established by promotional means. There is also a legal dimension, for it is essential that the brand names and trademarks are protected by all means available. The monopoly may also be extended, or even created, by patent, copyright, trade secret (e.g. secret recipe), and other sui generis intellectual property regimes (e.g.: Plant Varieties Act, Design Act).

In all these contexts, retailers' "own label" brands can be just as powerful. The "brand", whatever its derivation, is a very important investment for any organization. RHM (Rank Hovis McDougall), for example, have valued their international brands at anything up to twenty times their annual earnings. Often, especially in the industrial sector, it is just the company's name which is promoted (leading to one of the most powerful statements of "branding"; the saying, before the company's downgrading, "No-one ever got fired for buying IBM").

Brand extension

An existing strong brand name can be used as a vehicle for new or modified products; for example, many fashion and designer companies extended brands into fragrances, shoes and accessories, home textile, home decor, luggage, (sun-) glasses, furniture, hotels, etc. Mars extended its brand to ice cream, Caterpillar to shoes and watches, Michelin to a restaurant guide, Adidas and Puma to personal hygiene.

There is a difference between brand extension and line extension. When Coca-Cola launched "Diet Coke" and "Cherry Coke" they stayed within the originating product category: non-alcoholic carbonated beverages. Procter & Gamble (P&G) did likewise extending its strong lines (such as Fairy Soap) into neighboring products (Fairy Liquid and Fairy Automatic) within the same category, dish washing detergents.
