In the modern era, there are different modern networks, especially trade is the most popular now. So some people believe that advertising is more important in society than their real needs.
To begin with, would like to talk about products that are more attractive to buyers due to ads such as smartphones, notebooks and other devices. For example, it is a fact that a total of individuals, especially young people.They are impatiently waiting for the release of their old gadgets and wants to exchange new models. This event gives an opportunity to make an impression among their peers. In reality, they do not need to change their previous devices but they do it. Another situation concerns a huge number of goods that are believed to treat or benefit certain health issues. For instance, a lot of women spend money on magic pills which are able to lose weight. Needless to say, generally they do not help them.
On the other hand, sometimes advertised goods are really useful and give a chance to be aware of them. For example, when I have heard about a new device that helps to install a smartphone in the car highly convenient and flexible. I did not know about it in past and now I found it quite useful not only me maybe all drivers.
In conclusion, although society often falls under the influence of advertising and does useless shopping wasting their money, yet, there are cases when it is possible to find needed products through in advirtesement.
