The fact that so many magazines and other publications are
targeted at specific niche markets makes advertising in the right ones a very lucrative
opportunity.

Something I discovered in the mid-80's opened my mind to the
whole concept of target marketing. As a vice-president at BSA Advertising on
Madison Avenue, I learned a lot about the emergence and potential inherent in
"trade publications". When I discovered magazines like
"Waste Age" and "Personnel Management", I realized that if
these magazines were indeed reaching some very specific markets (and hard to
penetrate markets), then it would make sense to use them to advertise to those
specific target markets if the proper advertising vehicle existed.
Well that was then and this is now. Today there is hardly
a chance that just about any profession, interest or cause does not have a print
publication to support it. Just in the area of technology, I myself receive a
half dozen beautiful magazines every month. And I do respond to the ads that
interest me, so I myself serve as just another example of how effective trade
publications can be if you have a good product/service and a compelling story to
go with it.
And it goes beyond magazines. Webcentric publications, newsletters,
newspapers, even some aspects of television (especially cable) offer a variety
of highly targeted platforms by which to serve your message. But by far,
the most consistent vehicles for actively and successfully penetrating a
specific or even niche market is print. After that, I would have to say it
is the World Wide Web.
