It is believed by some that the main purpose of advertising is incresing the profit. I completely agree with this idea as it can bring opportunities to enhance their products and other aims are not beneficial.
It is obvious that when companies promote their products, they only aim at selling more products. By doing so, they can gain more revenue from those sold goods. If they have enough money, they can improve the quality of their product. As a result, enhanced products can attract a great number of customers. For instance, companies such as Samsung, Apple and Nike get most of their customers by their commercials.
Furthermore, advertising may have other purposes too. However, they might not be beneficial for the company. For example, if the publicity is only for entertainment, it may benefit watchers, but not manufacturers. That means, the money spend on making advertisements might be wasted. Once companies decide to promote themselves, their primary motive should be increasing the sales. Therefore, this is a primary goal in advertising.
To conclude, I strongly agree with the notion that companies should prioritize improving sales, because they can improve their products and other purposes are useless.
