What kind of company sells without advertising? Advertising can be in a trade journal, trade shows, magazines, newspapers, online, tv, billboards, etc...
Well, of course, in an economy driven by mass consumption, advertisements are certainly design to catch the consumer's attention and prompt the consumer to buy.
I attend technical meetings/conferences, but not tradeshows. I suppose if I'm interested in some technology, I'd contact people who likely use that technology and obtain information. With the internet, I can simply by-pass advertising and go directly to the technology of interest.
I generally ignore add in "magazines, newspapers, online, tv, billboards, . . ."
As for consumables, e.g. food, medicine, clothes, . . . I'd simply visit the appropriate store and buy whatever I needed. If I needed a car, I'd visit a preferred dealer and see what was available, or check a list online.
Actually, my wife does most of the purchasing of household needs.
We have used Consumer Reports in the past for some durable goods.
Otherwise, I prefer to see the product in person.
I generally avoid brand names. I prefer inexpensive stuff.
