作文：
Recently, I found on the internet that advertisements are regarded as another term of pollution to the public. However, hardly could anyone imagine the world it as it certainly brings huge amount of merits. As far as I could tell, the amount of pros that advertising has brought to people has far exceeded its cons.
In the first instance, advertising is the sales gimmick to Oligopolies. In such sort of market, firms complete with each other to gain the market shares. However, they will be reluctant to increase or lower their price because the information is interdependent and consumers have got tones of other substitutes. Therefore, the only way to promote their sales will be through advertising. Some consumers, on the other hands, do find such information useful while choosing what to buy. There is a common sense in it: hardly could an inefficient and stagnant firm invest a great deal of money on investment. In addition to that, big firms are able to lay the cornerstone to provide goods and services with better quality, which might benefit the consumers.
