Marketing involves identifying and satisfying customer needs through products and services. It includes activities like advertising, selling, and delivering goods and services. A market allows buyers and sellers to interact and exchange goods or services. Marketing aims to promote and deliver 10 types of entities to consumers and businesses: goods, services, experiences, events, persons, places, properties, organizations, information, and ideas. There are also different types of demand like negative, no, latent, declining, irregular, full, overfull, and unwholesome demand. Market segmentation, targeting, and positioning help organizations focus their marketing efforts. The marketing mix and extended marketing mix are tools used to determine a product or brand's offering.
