The difference between marketing and selling is more than semantic. Selling focuses on the needs of the seller; marketing on the needs of the buyer. Selling is preoccupied with the seller’s need to convert his product into cash; marketing with the idea of satisfying the needs of the customer by means of the product and the whole cluster of things associated with creating, delivering and finally consuming it.

Creativity thinks up new things. Innovation does new things. The difference speaks for itself. Yet the fluent advisers to business seldom make the distinction. They tend to rate ideas more by their novelty than by their practicability.
