Explanation:

Services marketing is a specialized branch of marketing which emerged as a separate field of study in the early 1980s, following the recognition that the unique characteristics of services required different strategies compared with the marketing of physical goods.

Services marketing typically refers to both business to consumer (B2C) and business-to-business (B2B) services, and includes marketing of services such as telecommunications services, financial services, all types of hospitality, tourism leisure and entertainment services, car rental services, health care services and professional services and trade services. Service marketers often use an expanded marketing mix which consists of the seven Ps: product, price, place, promotion, people, physical evidence and process. A contemporary approach, known as service-dominant logic, argues that the demarcation between products and services that persisted throughout the 20th century was artificial and has obscured that everyone sells service. The S-D logic approach is changing the way that marketers understand value-creation and is changing concepts of the consumer's role in service delivery processes.
