Their long survival gives the brand name an image of high quality.
7. Distinctive taste, ingredient or component Extension
A brand may develop a close association with a combination of taste. When it is well received in the market and survives long it enjoys a proprietary association of distinctive taste. Capitalizing on these properties, the brand could be leveraged in other product fields.

The logic of brand extension is to transfer a network of associations which drive consumer buying. The desired outcome is brand equity. However, brand extensions do not always create desired outcomes. The possibilities are different.
The parent brand can help the extension by providing brand associations to the extended brand. The extension also aids the parent brand by way of positive feedback. The extension may strengthen the parent brand by supporting the core associations. Sometimes, the name does not help the extension. It may even damage the brand name by creating undesirable attribute associations.
Brand extension is commonly followed by the marketer. But commonness does not mean that the extension is a shortcut to launch new products and services.
