Marketing involves more than just advertising and selling. It is defined as the set of activities involved in moving products from producers to consumers. This includes planning, pricing, promoting, and distributing goods and services. Major organizations involved in marketing include retailers that sell directly to consumers, and wholesalers that buy from producers and sell to other businesses. Before production, companies must determine their target market through market research to identify who their buyers will be. They then focus their marketing efforts on that target market. The four Ps of marketing - product, price, place, and promotion - make up a company's marketing mix.
