Re: RE: I understand advertising is necessary.
"Advertising - by it's own definition - is unnecessary"
It's unnecessary for the consumer in the sense that if consumer wants something they go get it and if they don't want something they won't. If a consumer wants more specific information or wants to find out options etc, that's what trade magazines/websites and comparison sites are for.
On the other hand, advertising is absolutely necessary for businesses... not only giant businesses with multimillion-dollar ad budgets, but also for small businesses, tradesmen, startups etc. You can't always get by with word of mouth.
