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 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
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.
