That is the question that every business owner must ask when designing or promoting a product or service. But most in business have experienced that marketing is not an easy task, as often it is hard to identify the consumer for a product or where that market exists.
Supersonic aircraft are technical achievements but sales are sparse due to a limited clientele.
Buying baseball mitts is for those who play baseball, yet the sport's popularity cannot compensate for a location in a Florida retirement community. Thus a quality product, right packaging, and financial expertise is of no avail unless a business has someone willing to buy and can reach that market potential. Marketing concerns the seller, the buyer, and the means to promote a product or service to achieve a sale. In all cases, the answers to these questions are defined by the target audience or market. Exceptions abound, such as inventions or true innovations, but generally the product is shaped by the market.
