This document discusses the effects of advertising. It begins by defining advertising as a form of marketing communication used to persuade audiences to buy or use a product. The purpose of advertising is then discussed as promoting new products and convincing people to prefer certain brands. Both positive and negative effects of advertising are outlined. Positive effects include advertising providing information to customers, improving product sales, and changing attitudes and habits. However, negative effects are that advertising can make people shopaholic, feel excluded if unable to afford products, and cause wasteful economic behaviors and environmental damage from constant innovation.
