Promotion involves techniques for selling products and seeks to make potential customers aware of and knowledgeable about products, persuade them to like products, and persuade them to purchase products. The promotional mix includes advertising, personal selling, sales promotions, and publicity/public relations. Advertising involves paid, nonpersonal communication from an identified sponsor to inform audiences about a product, and can pursue awareness, persuasive, comparative, or reminder strategies using various media like television, newspapers, radio, magazines, outdoor displays, and the internet. Personal selling involves one-on-one communication between a salesperson and potential customers.
