Product Marketing: Product marketing is a process of promoting and selling a product to a customer. Also product marketing is defined as being the intermediary function between product development and increasing brand awareness. For example, product management deals with the basics of product development within a firm, whereas product marketing deals with marketing the product to prospects, customers, and others. Product marketing, as a job function within a firm, also differs from other marketing jobs such as social media marketing, marketing communications ("marcom"), online marketing, advertising, marketing strategy, and public relations, although product marketers may use channels such as online for outbound marketing for their product. A product market is something that is referred to when pitching a new product to the general public. Product market definition focuses on a narrow statement: the product type, customer needs (functional needs), customer type, and geographic area.
