⇒ marketing

First, how do you satisfy the core while still expanding appeal? And second, how do you leverage your strengths against entirely untapped audiences--to the so-called "blue oceans" in popular marketing speak? ... Provide a new product that actually underperforms on an established industry metric for "progress," and substitute an alternative that typically is smaller, less expensive and easier to use. Initially, the "core" of any industry will scoff. But if the product is right, enough new users will be attracted to form an alternative definition for progress.
