Advertising has both positive and negative effects on society. Positively, advertisements can promote important causes like donating blood and increase awareness of health and safety issues. However, advertising can also negatively influence society by promoting harmful products like cigarettes and reinforcing stereotypes. Additionally, advertising aims to influence consumer behavior and make people feel they need to purchase unnecessary products. While advertising has benefited causes like disaster relief, it has also negatively impacted society by promoting consumerism and false social standards.
