The essential difference between a current S-Curve and a new S-Curve is that:

A. Established companies with large market shares can never move their businesses into a new S-Curve because of organizational redundancies that are too difficult to get rid of.

B. The new S-Curve emerges based on a portfolio of business ideas that are new compared to what the company has been engaged in so far.

C. A new S-Curve emerges only for new, challenger firms but cannot arise for existing incumbent firms.

D. The new S-Curve is simply an extension of the current S-Curve.
