In every walk of life, we can find advertisements. Radios, televisions, newspapers and mobile phones are filled with advertisements. Even when we read emails, we can find advertisements. Advertisements influence people's behaviour. It can be possible that I do not have that need without seeing an advertisement, but after seeing or hearing, I want to buy that thing. For example, I have a mobile phone. It is working well but after seeing the advertisement of another mobile with more features, I want that mobile now. Advertisements are the best way to create needs among the consumers.
The advertisement helps us in making life better. It motivates us to work hard so that we can buy better things. It gives knowledge about new products and motivates us to make them better than the things before. It is a great motivation to invent new products.
The advertisement also has a bad side. It motivates us towards materialism (物质主义). We want new things all the time, which motivates us to earn more money. Therefore, we do not have time for each other. We like to do those things from which we can earn more money instead of sitting with friends or family members.
In conclusion, every coin has two sides. In my view, the advertisement is a great source of knowledge. It also motivates us to work hard and make life more Interesting.
