Marketing management is the systematic organization and supervision of businesses' production and sales activities, focusing on market research to satisfy consumer demand and generate profits. Advertising is a crucial managerial operation, alongside finance, production, research and logistics. According to the management theory, marketing demands consumers vote with their money for the products that are essential to them. This decides the profitability of the business and meets the needs of the client. The majority mistakenly associated this idea with sales and promotion as marketing is the means of persuading the people to make an investment. The main component of sales is face-to-face interaction, where vendors interact with prospective consumers. Marketing uses media outlets and other means to generate demand and persuade individuals, even those without personal connections, to purchase goods or services. The goal is to understand consumers, so that the product or service matches their needs and sells itself, focusing on unnecessary sales.
