I wish advertisements were something one could "opt in" or "opt out" of so we really could choose to ignore them but they work because they put them all around us so they can't be ignored.
You opt out by simply thinking that what you are looking at or listening to is an advertisement, and that is all it is. It's quite simple, actually.
Advertising exists because it pays for itself in measurable amounts. If advertising lost money for a company they wouldn't do it
That is correct, which means that advertising costs are built into the price of the product.
No, I'm saying that being convinced to buy something you wouldn't have, didn't need, and didn't research properly is a stupid activity. One act of stupidity doesn't make a person stupid, it makes them more stupid than they would be if they had thought through everything more rationally
Good thing one act of "stupidity" does not make one "stupid" on a permanent basis. But how many do? And is the "stupidness" enduring over time? As for rationality and shopping, let's face it, defining need is a question of individual prejudice (I was going to say judgement, but we are talking about shopping, after all).
Many people are willing to make distinctions between needs and wants, but are not necessarily willing to have one without the other.
It is far more than a way to get something that exists known. If it were only about getting a product known they could do that much more cheaply by simply showing the product and listing its features... usually ads go beyond that to imply lifestyles, coolness, success, etc. The audience doesn't really have much choice to live a life free of advertisements without moving into the wilderness without contact with the outside world. The advertisers are focused on getting you to look at their ad by capturing your attention in some way and then force their product in front of you. Everyone is influenced by media, just to varying degrees and in different ways.
Yes, but listing the product and its features can often be a part of advertising, can't they? Besides, it would be so boring. As for the lifestyles, coolness and so on, seriously, who cares about all that? Individuals who makes purchases to pursue coolness and so on do this by actually thinking about what they want. They are not walking mindlessly into a store with drool running down their chin with their minds taken over by an advertising virus. They want to be current, cool and what ever else makes them feel good. Subtracting excess, is this truly evil?
As for being influenced by the media in varying degrees and different ways, that is true. People are also influenced by their own thoughts; by their education; by the books, art and music they read and listen to; by the ideas they expose thmeselves to; by the religious ideas they may believe in; by friends and family; by their own questions about their lives. The mass media are hardly alone in the domain of influencing, and the influence gets severely reduced the moment you ask a question that does not have a good answer, such as "what is cool, and does it matter if I am cool or not?"
