In the beginning, there was only one form of marketing. This marketing focused on pushing out advertising that interrupted people (think TV commercials, radio/magazine ads). Called outbound marketing, it used interruption as the primary tool and placed a product or service in the way of the actual information or entertainment that people were consuming. This form of marketing began to shift with the introduction of the internet. In 1999, Seth Godin published a book called, "Permission Marketing," during the era in which search engine optimization (SEO) and inbound marketing began to take shape. But is inbound marketing alone, enough to create growth?
