Advertising is defined as the non-personal communication of information, usually paid for and persuasive in nature, about products, services, or ideas by identified sponsors through various media. It aims to appeal to consumers' subconscious motivations like self-preservation, sex, greed, self-esteem, and curiosity in order to promote products. Advertising often uses logical fallacies and psychological techniques rather than giving logical reasons to purchase something. It has been criticized for perpetuating stereotypes and encouraging unnecessary consumption.
