Loyalty to a brand

If you buy from a particular store/shop/online store for your particular need and desire then you are loyal to that store/shop and that becomes a brand in a long run for you. This is how companys become brand after a certain time of period as there followers are loyal to them for a long time. You are not just buying there product because some body else is buying but you are buying becuase it gives you buying satisfaction ,value for money, mental satisfaction, acknowledgement among your circle and you take pride in buying from that place and then you refer that place  to other freinds and family memebers too. And this held companys responsible to continue making quality products and power to influence buyer's buying patterns and choices.
