This document provides an overview of services marketing. It begins by discussing the distinction between goods and services, noting that the line is sometimes blurred. Historically, goods were tangible objects that could be owned, while services were intangible deeds or performances. More recent definitions characterize services as activities offered by one party to another, often time-based, that create value through access rather than ownership. The document also notes that most industries have both tangible and intangible aspects and that services make up over half of GDP in most developed economies. Principal services industries include business, finance, healthcare, entertainment and hospitality.
