The marketing mix consists of four components: product, price, place, and promotion, which are interrelated with each other. The paper also presents examples of companies that successfully use the marketing mix and STP concepts, such as Apple Inc. and Samsung, and an example of a company that does not use these concepts effectively, such as Nestle. The conclusion highlights the importance of the marketing mix in taking decisions for introducing new products and developing effective distribution channels.
