How Does Diversity Impact Your Marketing Plans?

Recently my employer, Eastman Kodak Company , hosted Luke Visconti, one of the founders of DiversityInc.  Quoting from the website, "DiversityInc's mission is to bring education and clarity to the business benefits of diversity."  Kodak has been active in their thinking about diversity for over ten years now, and for good reason.
As Luke presented, I made a few notes that you might find interesting as marketers.  One of his assertions is that "mainstream marketing" is dying.  Companies who are most successful today have adapted to understand the needs of diverse consumers, while other companies are stuck in the past, creating products that cater to the traditional "mainstream" market which are not of interest to the fastest growing ethnic groups in the U.S.

Did you know that children in our country are already five times more racially diverse than our population who is over 70 years of age?  Did you know that the incidence of families in the U.S. that are multi-racial have increased significantly over the past ten years?

I'm amazed at how quickly this transformation is taking place.  I had been sensitized to this transformation a few years ago, and this recent update by Luke showed I've been out of the loop and not paying enough attention to this.

What is your business doing to recognize and adjust as the U.S. becomes more diverse?
