Nowadays, advertisements are everywhere where people go: in shopping malls, supermarkets, subways and even inside laptops. There is a common belief that this influences people in a bad way, as they tend to change their opinion about their own values, paying for things that are unnecessary for them. While I believe that many marketers live from advertisements and without them we wouldn't know about new technologies, goods and industries, I tend to believe that ads can be harmful, especially for people who do not have critical thinking.
