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
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.
It's the first company to build the mental position that has the upper hand, not the first company to make the product. IBM didn't invent the computer; Sperry Rand did. But IBM was the first to build the computer position in the prospect's mind.
The real barrier (to building a brand) is the human mind. It normally takes decades to build a brand because it takes decades to penetrate the gray matter in between your ears.
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.
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.
