It normally takes decades to build a brand... It's the forgetting of the old truth that allows a person to accept a new truth. You need to allow enough time for this forgetting to take place
Successful brands get into the mind slowly. A blurb in a magazine. A mention in a newspaper. A comment from a friend. A display in a retail store. After a slow buildup, people become convinced that they have known about the brand forever.
When a really new product comes along, it's almost always a mistake to hang a well-known name on it. The reason is obvious. A well-known name got well-known because it stood for something. It occupies a position in the prospect's mind. A really well-known name sits on the top rung of a sharply defined ladder. The new product, if it's going to be successful, is going to require a new name. New ladder, new name. It's as simple as that.
Only brand names register in the mind... What you should generally do is take a regular word and use it out of context to connote the primary attribute of your brand.
A branding program should be designed to differentiate your cow from all the other cattle on the range. Even if all the cattle on the range look pretty much alike.
If you can build a powerful brand, you will have a powerful marketing program. If you CAN'T then all the advertising, fancy packaging, sales promotion and public relations in the world won't help you achieve your objective.
