This post provides a good overview of three trends walking hand-in-hand to change the future of marketing.

I believe market segmentation walks slightly out front of the other two. It's market segmentation that provides us with the specific target market information that enables us as marketers to know which big truth best appeals to the people most likely to buy a product or service.

It's also market segmentation that makes it possible to communicate and build relationships with a target market through the media that its members use.

Of course I may be a little biased concerning market segmentation. The fact that I've developed an entire site and write a Monday - Friday blog on market segmentation testifies to that.
