Advertising is a super catalyst for sales, it makes good designs sell easier.
Onur Cobanli explains:
Good design should always benefit the society for which it is designed for. To create something beneficial to the society, you must think and reflect, you should study and analyze the deep needs of the society; you should know what makes the population happy, what motivates them. Good design is a lot about research, it is a lot about reflecting and it is also a lot about caring and loving; you cannot create universal good design if you do not care and love. Good design is love. Good design is loving people.
