All of the methods of communication that a marketer may use to provide information to different parties about the product. Promotion comprises elements such as: advertising, public relations, sales organisation and sales promotion.[4]
Advertising covers any communication that is paid for, from cinema commercials, radio and Internet advertisements through print media and billboards. Public relations is where the communication is not directly paid for and includes press releases, sponsorship deals, exhibitions, conferences, seminars or trade fairs and events.
After web 2.0, the capacity of the customers tell about the products that they have bought , making reviews and testimonials related to their use experiences , are examples of public relation,as well. This kind of behavior takes the dissemination of the product information over the internet space and creates the phenomenon known as word-of-mouth.Word-of-mouth is any apparently informal communication about the product by ordinary individuals, satisfied customers or people specifically engaged to create word of mouth momentum. Sales staff often plays an important role in word of mouth and public relations (see 'product' above).[4
