To what extent do you agree? In today's consumeristic society, people never miss seeing advertisements. I generally agree with the opinion that advertising has a significant influence on people because ads create trends and define value systems. Advertising makes people want products and services by presenting ideal images of lifestyle. For example, cosmetics companies use elegant models to show the beauty standard, driving people to be concerned about spotless skin, toned body and rich hair. Similarly, electronic companies nowadays provide home appliances connected to the internet and offer a more convenient life. Corporations publicise their values in a various way, including bill boards, flashy web ads and using influencers on social media. There is nobody who is not exposed to companies' marketing strategies, and people's perspectives are more or less influenced. Another important point to note is the imbalance of information. People are spoiled for choice to the extent where people cannot distinguish the difference. Advertisements claim their product is the best, and people tend to trust products by the frequency of ads instead of its quality. On the other hand, people's consumption pattern is subject to other influences. Word of mouth still does affect people's behaviour. People line up for restaurants where others go. Schoolchildren want toys their friends have. People look up customer reviews at online shops. Other people's behaviour and opinion do affect people's mindset. Another influential factor on customer behaviours is personal values. Vegetarians avoid meat for health or other reasons. Environmental activists might choose local products to do less harm to nature. Old folks might keep driving an old model car. People develop preferences on their own, and are partly insusceptible to advertisements. To summarise, although various personal and social factors can affect people's choice, advertisements play an important role in people's behaviour.
