Promotion is any communication used to draw attention to a product or service. The aims of promotion are to persuade customers to buy, inform them about the product, or remind them the product exists. Promotional strategies include advertising, sales promotions, public relations, exhibitions, direct mail, and personal selling. Advertising can be informative or persuasive and uses various media like television, newspapers, radio, and the internet. Sales promotions offer short-term incentives to encourage quick purchases. Public relations involves activities that improve a company's image through donations, sponsorships, and press releases.
