Marketing's Next Big Thing

I write a summer camp marketing blog called Camp Marketing News. Read primarily by camp owners and directors, many small business owners from all kinds of companies read it too for marketing tips and advice. A guy who runs his own small toy store emailed me today asking what I thought the "next big thing" in marketing will be. I wish I had a crystal ball. But in my opinion the #1 overlooked aspect in marketing is social media marketing to/for seniors, and the next big THING in marketing will be mobile marketing to seniors as well. Only time will tell if I'm right or wrong.
