The main reason of advertising is to rise the sales of products which are useless to some people, extent do you agree or disagree.
Some people think, advertising is created to sell products, what people do not need in their life. I think their ideas are true because good products do not need to advertise. The companies which don’t earn enough money from their goods, they pay for advertising company for boost their income and also blogers advertise things on social media like instagram, youtube and so on.
But good product do not need to advertising, it has its own client, which are have their own consuming system, they choose product, which has good quality. For this reason old factories do not advertise their goods. New and amateur factories need this more compared to the old ones.
In another hand, companies must do this. Coin has two sides when they sell their product they have to pay taxes to the government and also they should pay the payment of their license. For this reason they need this. As I said it helps to boost their income and also workflow. If they earn more they can expand their business. If they do not do this they remain under shadow of older and famous ones.
In conclusion advertising have two sides, first one is good for businesses, it helps to increse workflow, second is bad, it may advertise wrong thing to wrong person, for this reason they have to put advertises on many groups. For example for adults they can show ad of tools they can use their daily life, for kids they should show toys and candies and also for alderly people, they have to show ad of medicine.
