Market segmentation does more than simply find new markets, critically important though that it is. Markets and purchasing patterns evolve. The person that buys one product today becomes a steady user tomorrow. Sales don't occur in isolation. There are related purchases to be made, related support to be given, related individuals who will hear word of mouth recommendations and comments...

This gives companies superb opportunities to expand their market and to boost growth and revenues.

Market segmentation provides methods.

Know your market segment and you'll know which consumers will respond best to new product offering and to new services.

Markets evolve, and old markets contain the new markets within them. Market segmentation helps you to study and test the markets you have so you can develop and profit from the markets of tomorrow.
