Media exercise In recent years, we have seen many trendy commodities that could sell out in a couple of hours, for example, Apple products. Although their large numbers of sales illustrate the power of advertising, I think sometimes these products are not what consumers really need. Advertising is a significant tool for companies to inform people of their service and merchandise. In advertisements, food and drinks look appealing and electronic gadgets seem portable and convenient. Also there would be celebrities telling us the latest fashion. From television, websites, radio broadcast and street posters, we could see numerous ads here and there every day. Most of them are both entertaining and informative. However, as corporations are driven by profit, they may use exaggerated and misleading commercial ads to increase the sales of what they sell. They probably use special effects to make fast food look fresh and nutritious which in fact will only affect people's health. Some advertisements may use sexual or violent images to attract attention, which will have negative effects on children's development because children will possibly copy those inappropriate behaviour in ads. Young people are encouraged to buy expensive goods to look fashionable and have similarities with their friends. In my opinion, it is an effective approach to use advertising to boost sales income and advertising industry is also making contributes to economy. However, I think advertisements should be regulated so that consumers could make well-informed choices to meet their real needs.
