The origin of marketing can be traced back to the economic sciences and it was first studied and discovered by economists who couldn't find another explanation for the fluctuation of the demand of a product outside the fluctuation of the price. The classic economic theory generally connect the demand of a good to the price and need for that specific good. But when the demand of a non essential good continues to increase despite of the rise of the price, the economic theory failed to explain this trend with the traditional variables and that is when economists introduced the marketing into the equation.
