This is manifestly false. An efficient market based on rational consumers doesn't require advertising. Advertising serves to skew consumer opinion away from rational behavior (in the economic sense of maximizing utility divided by price), so in fact it can be argued that it will always make the market LESS efficient.
An ideal consumer would browse the market and read non-paid reviews, and choose the product they need. No use for advertising.
An ad-converted consumer will see advertising, and think that the advertised product is necessary even if it isn't, or think it's better than the competition even if isn't.
This is completely false and implies lack of understanding of market dynamics.
It's also insulting to the reality of any person or group who's actually created a business, and wants to get the word out about their product - as if the word magically just 'finds out' about it.
I'm shocked at the level of anti-knowledge and anti- rationalism on a forum of such intelligent people.
Of course advertising can 'skew' people's emotions, nobody doubts inefficiencies. If there were no ads, it would be tantamount to the banking disaster - it would go down like dominos.
Targeted ads are the only hope for a lot of small companies playing into long niches, as I say, without them, you get Nike, Apple and Ford for everything.
I'm not doubting the effectiveness of advertising, quite the opposite. Of course that if some players are advertising, anyone who isn't is at a major disadvantage.
But cigarettes were a very good study in what happens if you remove advertising from an industry - nothing much. They get to save a lot of advertising money, and the industry itself may shrink if there is no real need for it (for cigarettes, it reduces the rate at which people start smoking, even if it doesn't significantly reduce the rate at which smokers buy cigarettes).
Of course, people would still buy clothes and consumer electronics and cars if there were no advertising - these are all useful products. But most likely, the contrary of what you are claiming would actually happen: all these huge players would find themselves competing much more on price with small "no-name" producers if they couldn't sell an image of exclusivity, particularly in the case of Nike and Apple. Especially in fashion, most non-luxury brands are built entirely on advertising, as there is no real quality or style difference between them and by-the-pound clothing you get at thrift stores.
So yes, prices may fall like dominoes, but only because the market would become more efficient, bringing prices more in-line with costs, quality, and utility, rather than "prestige".
