There was a time when marketing was simpler. When advertising men wore sharp suits with ties and drank martinis. When a web site was the domain of a spider.And when media selection boiled down to a choice between TV and print. Things have changed a little. Ad men (and women) rarely wear ties these days. More importantly, there are so many media channels now – from email to Facebook to blogs to YouTube and eBooks – it’s often hard to know where to start communicating with potential customers.
